Mycodraw simulates mycelium growth, using an image as food. We were inspired by the work we found on <html><a href="http://onecm.com/projects/mycelium/" target="_blank">this site</a></html>. Originally Rafael converted his mycodraw program from java to javascript (which took a VERY long time), but the script only worked on some browsers :( We had to settle for the gif instead. | ||

The concentration was extremely low, so an overnight culture was made from the glycerol stock to be miniprepped tomorrow. Another transformation was done using remaining previous minipreps of ''nptII BB''. Cultures were made of the third Gibson attempt, and a colony PCR performed. When run on a gel, the non-GC fragments were too small, but some GC colonies looked good. Finally, ''nptII BB'' was digested with XbaI and PstI, then column purified.

+ | |tech=Due to the contaminated EB found yesterday, our EB supplies were checked to ensure no further delays. To begin, the Gibson ''hph'' was submitted for sequencing, and pAK13AD and pC13Z were miniprepped. A PCR of pC13Z, pC13F, pCP13X, pC13M, and pC13E was then run with primers 31 and 32, the standard pSB1C3 primers. A gel was run to check the PCRs. All the PCRs looked successful except pC13M and pC13E, which had nonspecific bands around 1kb. A new technique was used on a few of the digests involving a restriction cocktail of enzymes to cut the DNA. Plasmid pAK13AD was digested with EcoRI, SpeI, SacI, and ClaI so that it could be placed in pSB1C3. We used SpeI instead of PstI due to the small distance between the PstI and the SacI cut sites. Plasmid pC13F was digested with EcoRI, SpeI, and KpnI so pAK13AD could be placed in it. Plasmid pAK13D was digested with SpeI and PstI so ''crtI'' and ''crtB'' could be placed in it. All the digests were then column purified rather than gel purified--a move which has improved our ligation efficiencies. The purifications were quantified. Cultures were made for pC13P and pC13K and, finally, pAK13AD was dephosphorylated then ligated into pC13F in order to make pC13AH. | ||

- | + | |tech=Sequencing results came back positive for the Gibson cloning of ''hph'', so a culture of the successful Gibson colony was made. pC13AH was transformed and plated, and pC13K were miniprepped. pC13X, pC13F, pC13Z were digested with SpeI and PstI along with pC13P (XbaI/PstI), and all were column purified. Reran a PCR of pC13M and pC13E, and one of pC13K with standard biobrick primers. All PCRs were cleaned, then run on a gel along with pBARGPE1 which had been digested with NotI. pC13E and pC13M looked good, but pC13K was too short. pBARGPE1 had a 4kb fragment (super-coiled) and pBARGPE1 with NotI had a 5-6kb fragment, meaning it has a NotI site. Ligations of pAK13D to inserts pC13Z, pC13X, and pC13F along with vector pC13P to inserts pC13Z, pC13X, and pC13F were performed. Also, overnight digestions of pC13M, pC13E, and pC13K with XbaI and PstI were set up. Transformation was attempted for pC13AI and pA13AJ, but the cuvettes weren't cleaned properly so it failed. Finally, our dwindling supplies prompted the ordering of more SpeI and membrane filters. | |

A band showed at exactly 1.8kb as expected. pC13M was ligated to pAK13D, placing ''crtB'' downstream of the T7 promoter. pC13E was ligated to pC13P, placing the ''T7'' polymerase gene downstream of ''PtrpC'' (a native fungal promoter) - this is the first part of our genetic circuit with the second being the ''T7'' promoter upstream of various genes (''GFP'' and ''RFP'' for diagnostic purposes - to quantify promoter functionality and the carotenoid genes for proof of concept). Plates of pC13AH (T7 + crtY) had many colonies, so they were restreaked, and colony PCRs were run while cultures were made of some of the colonies. A gel of the PCRs was run (image name was pC13AHcolonypcr7-17-13); gel was inconclusive (correct band was accompanied by strong incorrect band at 1kb).

However, sequencing of pC13BF was unsuccessful and we reran the PCR of pC13F in order to append BamHI and KpnI cut sites for ligation with pA13BE. We ran another digest screen for pC13AY but many lanes did not have bands so we will retry it tomorrow. We also amplified ''GFP'' from pC13Z and ''mRFP'' from pC13AK using primers 23 and 24 in a Q5 PCR. Afterwards, a gel screen on PCR products was run to verify that the correct genes were amplified. The gel image indicated consistent bands with lengths of 0.7 kb, thus the PCR to obtain ''GFP'' and ''mRFP'' inserts was successful! We made a rough draft of our protoplasting protocol to attempt in the near future, too. We then rummaged through previous notebook entries to figure out the problems with ''crtB'' and ''crtI''. | ||

|tech= We ran a PCR of pA13BW. The ''CRE'' gene amplified correctly and the sample was column purified, yielding 54.8ng/uL (with GC enhancer) and 49.9ng/uL (with non GC enhancer). We ran out of supplies to miniprep, so we pelleted pA13AM and pC13BG cultures and began to not so patiently await the arrival of a new miniprep kit. Our PCR of pC13F to append BamHI and KpnI cut sites yesterday failed completely, so we digested pC13F with KpnI to linearize it with an internal cut site in ''mRFP'' for another PCR to be run tomorrow. Another gel was run of the pC13AY digests and all lanes were blank. There may have been an issue in quantification by nanodrop that was reading over 1000 ng/μL that mislead us into using low volumes of DNA for digestions. We decided to electroporate with the remaining pC13AY to miniprep and redo gel screening. On a brighter note, our restriction cocktail digestion of pA13BE with BamHI, KpnI and SacI showed a band at 500bp, which is the approximate length of ''PpelA''. We also searched for a pAK13AN miniprep in the DNA storage box and for a glycerol stock of the same plasmid. We couldn’t find either. However, we did obtain a plate of colonies that had been transformed with pAK13AN. We picked colonies off this plate to miniprep and send off to sequencing. In addition, we column purified our inserts from the PCR run yesterday of pC13Z and pK13AL. We then quantified inserts after column purification. After, we digested backbones pAK13D and pC13P with SpeI and PstI and vector dephosphorylated both. The inserts, ''GFP'' in pC13Z and ''mRFP'' in pK13AL were then digested with XbaI and PstI. We ran a gel of backbones and inserts for confirmation of digests. Unfortunately, the results showed no bands from DNA. Perhaps there was not enough DNA from backbones for proper visualization. We also received materials for protoplasting today, and autoclaved or sterilized the supplies in whatever way we could. We made a filtration system such that all the filtering process during <i>G. lucidum</i> protoplasting will remain sterile. We made another stock of <i>G. lucidum</i> in CYM media, as well as 25 mL cultures of pC13F+pC13BK, pC13BL, pC13BJ, and pC13BM. We made glycerol stocks of pC13M and pC13K from glycerol stocks.

|tech= We still didn’t receive a miniprep kit so we pelleted the pC13AY cultures. The PCRs we ran on pC13F to append homologous regions and append cut sites may have been successful. DNA was present but in low concentrations that we could not check on a gel. We had transformants for pC13BX and pC13CJ so we ran a colony PCR and made cultures. The colony PCRs showed little to nothing on the gel, perhaps because Taq polymerase lost activity. We will miniprep the culture and use Q5. We also attempted a restriction cocktail digest today for both ''mRFP'' and ''GFP'' inserts. We cut pC13Z and pC13AK with Xba, PstI, SacI, and ApaLI. We also performed a colony PCR of pC13AT cultures and pC13AU cultures using primer 23 and 24 to verify length of inserts. The lengths should be around .7kb for each insert. When we ran a gel of the PCR products, the colony PCR showed a .7kb insert for pC13AT colony 1 and a .3kb insert for pC13AT colony 2. The bands for pC13AU were inconclusive. We will miniprep the potential pC13AT colony 1 and send for sequencing once the miniprep kit arrives. We digested our plasmid pAh13G with SphI in order to create linear DNA for fungal transformation. We attempted to transform this into what <i>G. lucidum</i> protoplasts we had generated, but the electroporation lead to arcing. Arching most likely resulted from the sodium citrate in the cell solution which we were instructed to use by the literature.

|tech= We transformed and plated the pA13AW ligation from yesterday. We also retried the PCR to append KpnI and BamHI cut sites to pC13F again, using the newly received Q5 mastermix and higher annealing temperatures. We ran a massive gel screen and found that the cut site PCR and Gibson assembly may have been successful, but that the construction pC13AY most likely failed. We then digested pC13F with cut sites appended with BamHI and KpnI for ligation with pC13BE to make pC13BF. We digested pA13CZ with SpeI and PstI, which is to be ligated with ''GFP'' from pC13Z and ''mRFP'' from pC13AK. We ligated the Xpa1, Pst1, Spe1, Apa digested pC13AK and Spe1 and Pst1 digested and dephosphorylated pC13BG to make pC13CG, which we transformed into BL21-A1 cells to check transformation efficiency. We also tranformed into DH5α and plated both for comparison. The sequencing results of pC13BJ 7, pC13BK 6, pC13BL 7, and pC13BM 6 confirmed that we were successful, so we made new cultures to create glycerol stocks from, but the initial cultures were thrown out and the plates were difficult to re-pick from, so we hope that cells made it into the culture and have the correct plasmid. We did a PCR clean-up for pAK13AB, pAK13AC, pC13A, pC13A, pC13N, pC13L. We digested pC13I, pC13J, pC13N, pC13L with XbaI & PstI, pAK13AB & pAK13AC with EcoRI & PstI.

The <i>G. lucidum</i> ''PgpdA'' and pC13F parts with homologous regions needed for Gibson assembly and found them successful. We then ligated and transformed pC13BF although it sparked during electroporation, so we will most likely have to retransform. A sequence confirmation came back for pC13AQ! pC13AT turned out to be ''PtrpC'' and ''mRFP''.Thus, we redigested ''PtrpC'' in pC13P and pCg13Y with SpeI and Pst1-HF. pCg13Y will be used to create pC13CB. We also redigested pC13Z, pC13AK, and pC13AQ with Xba, Pst1-HF, ApaI and Sac1-HF in order to get necessary inserts. We threw away the cultures of ''pC13BJ" 7, ''pC13BK" 6, ''pC13BL" 7, and ''pC13BM" 6 from yesterday and didn’t make glycerol stocks because we were not sure if we got the correct colonies. We will transform the sequence confirmed minipreps when more DNA is needed. We attempted site directed mutagenesis of ''PtrpC'' + ''hph'' + ''TtrpC'' in pAh13G. The extension time was a little short for pAh13G so it might not work. We ran gel a gel, which had a band at 100 base pairs, meaning it didn’t work. We will attempt this again tomorrow with a longer extension time. Colonies of BL21-A1 and DH5α with pC13CG grew. BL21-A1 seems to have a higher transformation efficiency.We started cultures and performed a colony PCR from the DH5α plate. We ran a gel of the colony PCR and pC13CG 1, 3, and 4 had the correct band at about 1.8 kb. pC13A and pC13F (XbaI,PstI) did not have enough DNA. As a result, ligations for creating pC13I and pC13J are on hold. We ligated and electroporated pC13AF, pC13AG, pAK13CR, pAK13CS from other digestions, and plated them overnight. We found the the transformations of pC13BR and pC13BQ were too efficient and had to restreak the plates in order to isolate single colonies. We ran colony PCRs of pC13BU, pC13CC, and pC13CD, and at least two copies of each construct seem to be successful! | |

Digested ''T7 polymerase'' PCR with XbaI and PstI and pC13F with BamHI and KpnI (sites were appended via PCR). pC13F that was digested with XbaI and PstI as well as with BamHI and KpnI were dephosphorylated for ligation. After confirming ''T7 polymerase'' PCR on a gel, it was ligated into pA13AM and pC13P. Additionally, ''Pc + T7 polymerase'' was ligated into pC13F and ''PpelA'' was ligated into pC13F. We ran those PCR's for the Gibson of pC13BN on a gel. ''lox'' 2 worked, but ''lox'' 1 did not, so I purified ''lox'' 2 and reran the PCR of ''lox'' 1 (it is in the small fridge labeled ''lox'' 1). I also made glycerol stocks of pC13BX and pC13CJ so that we have those in case we need to do more minipreps on them. We also had transformants for pC13CN so I made cultures with spectinomycin for all of them and ran a colony PCR on them. The colony PCR did not work due to incorrect protocol. We do not have the correct primers to do a PCR on this plasmid because its in Bbb format, so we just have to assume the plasmid is present because the cultures are growing in Spec. Tomorrow we need to miniprep those cultures that are in the incubator. We blended <i>G. lucidum</i> and made two 100mL cultures with 75mL cells and 25 mL cells. We will now let these grow for 2 days before attempting protoplasting once more. We created large batches of vectors (pC13F (XbaI,PstI) and (EcoRI-HF,PstI), pC13D (XbaI,PstI)). pC13AG sequence is sequence confirmed! We tried to dephosphorylate, but mistakenly used DNA Ligase on pC13F and pC13Q instead, so we’ll have to redo that tomorrow. | |tech= One colony of pC13BH had a good banding pattern and was submitted for sequencing.

We ran a Gibson of pSB1C3 with both pC13CL and pC13BA. Both of these were transformed, ''Cht1_2'' into DH5a (time constant 4.82) and ''afp1'' into BL21 (time constant 4.84). We made glycerol stock of pC13BN. We ran a gel of pSB1C3 PCR from yesterday, which was successful, and performed a PCR clean up. We digested pSB1C3 and pC13CN with HindIII and BglII. We ligated these together to create pC13CO and transformed it into DH5a (time constant 4.82). We miniprepped pC13BN culture and did a double digest on pC13BN culture with KpnI and HindIII to see if internal cut sites were present. There was some digestion that occurred when it was run on a gel, so we are confident the sequence is correct. We double digested pC13BN again with KpnI and HindIII.

We got transformants for pC13CO, pC13BN + pC13CD, pC13BN + pC13Y, pC13BN + pC13BQ, and pC13BN + pC13BR. A colony PCR was performed, and a gel of the PCR products looked good for only pC13CO colony 2. No positive inserts were present, so maybe the ''lox'' construct is not correct. To check, we will sequence it tomorrow. Afterwards, we miniprepped pC13BF, pC13P, and pC13Q and digested pC13BF. We ran the gel for pC13A and did a PCR clean up for it, as well as for pC13J and pC13L. We also digested pSB1C3 with XbaI and PstI, and miniprepped pC13CV, pC13I, pC13AH and pC13AG. We attempted to run another gel of our PCR product to create Gibson assembly parts, which looked even worse than yesterday. We also did a PCR cleanup of pC13BJ, pC13BK, pC13BL, and pC13BM. | ||

+ | |text= After picking up our pieces from the Clark Hall machine shop, we focused on cutting our insulation to the proper dimensions. Initially, we tried cutting it with a razor blade, but after some rather sloppy results, we decided we needed a more efficient cutting method. Our next attempt involved heating a thin wire and melting through the insulation. This produced better results than the razor blade, but was way too slow. Finally, we decided it would be best if we just resorted to power tools. We bought a jigsaw from Home Depot and cut the insulation like it was cheese. After, we gazed fondly upon the jigsaw and reminisced about high school woodshop. | ||

|tech= We submitted pC13BC, pC13BV, and pC13CE for sequencing. We reinoculated cultures of pC13BN, pC13CL, pC13CO. Then, we conducted a preliminary test on activity of ''afp1''. We cut circles of various sizes from dialyzing membranes and dipped in grown ''afp1'' in BL21 culture. The membrane pieces were then placed on the fully grown <i>Aspergillus</i> plate. This preliminary test will see whether or not there is activity of ''afp1'' on the <i>Aspergillus</i>. We are hoping for a ring of death on the <i>Aspergillus</i> plate. Unfortunately, there were no colonies for the ''PgpdA'' assembly. We then ran a gel for some of the remaining assembled DNA and no bands appeared. We also digested pC13AU with Xba and PstI to ligate downstream of pC13BR and pC13BQ. We then column purified pC13BQ, pC13BR, pC13AT, pAK13AO, pC13AU, pC13F.

Initial tests with the temperature sensor yielded very positive results. We were able to successfully set and reach a target temperature with our sensor/feedback system. Unfortunately, our humidity sensor malfunctioned while we were running tests, however, we were still able to gather some data. Initial humidity tests indicate that our misting apparatus is able to produce a 12% increase in humidity over a time span of 8 minutes. Using a hotter water supply, as well as allowing the misting apparatus to run for longer would certainly allow us to increase humidity even more. | ||

+ | |tech= Today, parts for pC13BN were DpnI digested, purified and Gibson assembled. We also performed a PCR of pC13F to append BamHI and KpnI restriction sites to the pSB1C3 backbone. The goal was to digest pC13F with BamHI and KpnI and ligate <i>PpelA</i> in place of ‘’mRFP’’ using BamHI/KpnI digested pA13BE (part pHNU3pelA). pA13BE is a plasmid generously given to us by the Turgeon lab at Cornell and contains the ‘’PpelA’’ flanked by BamHI and KpnI restriction sites. Thus, transferring ‘’PpelA’’ to the pSB1C3 backbone (creating the part pC13BF) would allow constructs made with ‘’PpelA’’ to be BioBrick submissible. All 4 of the PCRs (in addition to the BamHI/KpnI digestion of pA13BE) seemed successful upon gel electrophoresis. We also received the <i>A. nigers</i> <i>pkiA</i> promoter (‘’PpkiA’’) and <i>xlnD</i> terminator (‘’TxlnD’’) from the Wageningen team, which we plan on characterizing by cloning ‘’GFP’’ and ‘’mRFP’’ (in separate constructs) between the two. | ||

Then we digested the newest PCRs with each of those sets of restriction enzymes, and dephosphorylated the vectors. We ligated pC13AT, pC13AU, and pC13AV into both pAg13H and pAh13EA, as well as pC13CE into pAg13H, and pC13CC in pAh13EA. Gibson assemblies of pC13DU, pC13DV and pC13DW were plated with Spectinomycin. Made 1 L of minimal media and 1 L of induction media. We also transformed pC13P + pC13BA which resulted in very dense colony growth. Attempted to pick 5 colonies and culture them. Also column purified pC13CY. Carotenoids received the right forward primer for amplifying ‘’crtE+crtB+crtI’’ in pC13A, and we ran a long, two-step PCR with an extended annealing time and 40 cycles. | ||

Any bacteria containing the new vectors have been growing very slowly under selective pressures, since they might be low-copy compared to our usual plasmids. We ran a PCR of pS13EB to prepare for Gibson assembly. Ran a gel of pS13EB, bands at 10,000 and 2,000 indicating probable correct product. Also, pC13DU, pC13DV, and pC13DW were miniprepped. We also digested pC13AI with SpeI and PstI. We then dephosphorylated, purified, and ligated pC13CY into pC13AI. We then miniprepped 5 colonies of pC13P+pC13BA, column purified the Psal, and quantified each. We column purified the SpeI/PstII digested ‘’PpkiA’’, the XbaI/PstII digested ‘’TxlnD’’, the XbaI/PstII digested pC13Z, and the XbaI/PstII digested pC13F. Next, we vector dephosphorylated ‘’PpkiA’’ and subsequently ligated ‘’mRFP’’ (from pC13F) and ‘’GFP’’ (from pC13Z) downstream of ‘’PpkiA’’. The carotenoids team ran a gel for the PCR products of pC13A and observed 2~3kb bands for all the lanes. | ||

I'm really excited about having these new members on the team. There were many awesome interviews, but now we have to sit down and make hard decisions on who to take, as most of last year's members are graduating, so there's a limit to how many new members we can train. This is going to be a tough weekend.

We met with Professor Gillian Turgeon, who does fungal transformation with Cochliobolus heterostrophus, an ascomycotic corn pathogen. We can get a few of the genes we've been looking for from her, yay! We also met with Professor Teresa Pawlowska, who directed us towards some other fungi and resources for fungi, as well as provided some background on fungal biology. As for the rest of the semester, we're letting everyone off the hook-- we don't want anyone to fail their exams because of iGEM!

show technical details
The drylab team met briefly on June 17 to begin discussing some ideas. We went over some of the growing methods for Ganoderma lucidum, brainstormed some non-packaging related ideas for a fungal biomaterial, and discussed how we could test some of the physical characteristics of the final product. We thought it might be a good idea to test the thermal conductivity if it were to be used as a drinking cup. We also determined that people probably do not want to drink out of a fungus cup.

The drylab team met to update each other on some of the preliminary research. The main focus of this meeting was the development of a growing protocol. Sara found a professor that we could contact in the material science department for help regarding the testing of material properties. Rebecca and Manny looked into what different aspects of the fungi we could model, such as growth, decay, etc. Ritvik brainstormed some more ideas regarding the potential uses of this material, and came up with the idea of using it as insulation.

We started cloning crt genes downsteam of the T7 promoter. Because the T7 promoter is too small to extract as a fragment, we're placing crt genes downstream, then transferring the promoter+gene fragments back to pSB1C3. Today we digested crtY and the T7 promoter plasmid, but the digestion of crtY failed.
-Rafael

We redid the digestion of crtY and the T7 promoter plasmid from yesterday, apparently successfully this time. We also started liquid cultures of pBARGPE1, a plasmid we got from the Fungal Genetics Stock Center.
-Rafael

Crossing our fingers, we gel extracted and ligated the ostensibly successful digests of crtY and the T7 promoter plasmid, and then transformed. We also digested crtI and crtB, other carotenoid genes that we will also be putting under the T7 promoter, and miniprepped the pBARGPE1 that had been grown up last night.
-Rafael
June 30th
show technical details
Unfortunately, there were no colonies on the transformation plate for T7 + crtY, so we redid the digestions for those. We also digested TtrpC and nptII for the eventual cloning of a PtrpC+nptII+TtrpC construct (we have to put the parts together in reverse because nptII contains a PstI site, which we will be trying to remove as well). Gel extractions of digested crtI and crtB were also empty (insignificant concentrations), so these digestions were also redone, and all were run on a gel, which looked mostly okay.

There were no transformants, again :(. On the other hand, we received our tube of Ganoderma Lucidum from Dr. David Hibbett today! Once more with feeling, we redid the four digestion-ligations for crtI, crtB, crtY, and nptII. We also amplified hph, the hygromycin resistance gene, from one of the plasmids we got from Dr. Turgeon's lab, as well as pSB1C3 backbone, and we will use Gibson assembly to put them together (as hph has both EcoRI and PstI sites)-- the gels looked good for both of these. Finally, we submitted pAb13T (pBARGPE1) for sequencing to determine the sequences of the Aspergillus nidulans gpdA promoter and the bar gene, which confers phosphonothricin resistance.

All transformations failed yet again, and were repeated once more. Four tears shed for the lost. hph was Gibson-assembled, and we ran a Q5 PCR of the bar gene, under the assumption it matches other published bar sequences, and the product digested and ligated with pSB1C3. We also ran site-directed mutagenesis on nptII (pCg13R) to remove its internal PstI site.

Several constructs were ligated. The mutated nptII (pCg13S) was ligated with TtrpC. Assembled bar in pSB1C3 and submitted for sequencing. The Gibson of hph into pSB1C3 was rerun. An experimental method of ligating crtY into pAK13D upstream of the T7 promoter was tried as an alternative to gel purification and PCR purification, since we lack the primers to PCR and gel purification interferes with ligation.

This week, drylab split up so members could focus on their strengths. Rebecca and Sara began designing our feedback controller, with some much appreciated advice from the previous drylab team leader, Dan Levine. Ritvik, Manny, and Mac began coming up with design considerations for the incubation chamber. We were most concerned with size; too small and it wouldn't be useful, too big and it would be difficult to control any variables. We eventually decided that a 1'x1'x2' chamber would probably be a good compromise. Rebecca, Sara, Ritvik, and Mac also attended machine shop training this week. In order to complete our training, we each had to construct a small aluminum lamp using a milling machine and a lathe. Fortunately, everyone emerged from the training session one lamp richer, and with a full set of fingers on each hand.

The Gibson sequencing came back positive! We then digested pC13X, pC13F, pC13Z and pC13P, and ligated pAK13D to inserts pC13Z, pC13X and pC13F, and pC13P to inserts to inserts pC13Z, pC13X and pC13F. We ran a PCR for pC13M, pC13E and pC13K. Sadly pC13K did not work… Transformation was attempted for pC13AI and pA13AJ but they both failed--we suspected that the cuvettes weren't cleaned properly.

Our materials are here and everyone in the fabrication group has returned to Ithaca! This week, Manny and Mac focused their efforts on getting the plastic cut to the proper dimensions. Unfortunately, this proved more to be more difficult than anyone could have imagined. After transporting a rather hefty 48"x48" piece of plastic across campus from Weill Hall to the Emerson Lab machine shop, we were told that we would have to take it elsewhere to have it cut (plastic is bad for blades). Disappointed, but never defeated, we decided to try our luck with another machine shop. Also, carrying plastic around campus isn't much fun, so we held it on the roof of a car instead (not recommended). Fortunately, no traffic violations were received, and the Clark hall machine shop was more than happy to cut up our plastic for us.

This week, the incubator box was completed. The fabrication and electrical groups came together to begin combining and testing. Initial tests with the temperature sensor yielded very positive results. We were able to successfully set and reach a target temperature with our sensor/feedback system. Unfortunately, our humidity sensor malfunctioned while we were running tests, however, we were still able to gather some data. Initial humidity tests indicate that our misting apparatus is able to produce a 12% increase in humidity over a time span of 8 minutes. Using a hotter water supply, as well as allowing the misting apparatus to run for longer would certainly allow us to increase humidity even more.

We made a lot of changes to the presentation tonight, and it is an almost polished form now. Arun switched to his next color scheme: a deep Cornell red with baby blue banners. Eric has gotten his part of the script memorized. He will be speaking about the three components of our project. The fungal toolkit, and its implementation through the carotenoid pathway and antifungals expression. Hannah has also prepared her part on human practices. In addition she has prepared an analysis on the market trends towards bioplastics.

Today we met again with Oat to make some changes to our images. Arun moved onto his next color scheme: the same deep maroon with elephant grey banners. In addition, the data, and ending slides will follow a baby blue and off white color scheme. We also made a few of our slides (our styrofoam map, standoff figure, and toolkit image) fancier and more attractive. Arun also experimented with backgrounds of clouds, dirt, and toolkit to make the introduction slides very sharp. It look like we now have a solid design for our presentation.

Today a meeting was held to determine the timeline of events up until the world competition. The temperature and humidity circuits were set as high priority, particularly the integration of electronics with the incubator. Low priority were setting up a wireless connection, implementing a power switch, performing a cost analysis, and adding ventilation to the incubator.

The heating pad which was ordered arrived, but integrating it with the arduino circuit did not seem to be a realistic goal within the time frame before competition. Instead, multiple resistors were connected to the circuit, and it was found that a greater power supply was needed, along with more resistors of lower resistance. Transistors, resistors, and breadboard adapter plugs were ordered.

Characterization of pC13BC and pC13BV was unsuccessful. We began cloning of completed constructs into new vectors for C. heterosporus transformation, as well as cloning of Psal, and grew cultures of PtrpC with ‘’afp1’’. Gel electrophoresis showed that none of the components of the carotenoid pathway yesterday work. We realized that the forward primer we used is wrong and designed a new one.
