Lab work

A - Aerobic/Anaerobic regulation system

((((((((((((((((((((====1 - Obtaining Δ fnr E. coli strain by transduction to test our biobricks====

Abdou, Anais, Damir, Nadia, XiaoJing

We do the exprience again because the lysis made on wensday didn't happen. It's probably because the phage strain was too old ( 2001)

Protocol : transduction

Picture: lysed cells comparison.

0µl phage(control): the petri dish is cloudy, bacteria are not lysed.
50µl phage: the petri dish is clear, bacteria are lysed by phages.
We used a wild type strain to keep a stock and a Δ fnr E. coli strain to obtain phages that might have encapsidated a Δfnr::Km fragment.

10µl,50µl and 100µl petri dishes are clear so phages are multiplied.

We let the antibiotic over night to select the right strain. ))))))))))))))))))))))

Objective : obtaining Bba_K1155007

1 - Extraction of Bba_K115007 from DH5α

Abdou

Protocol : Hight copy plamid extraction

We used colonies number 10, 14 and 15.

Nanodrop

Bba_K1155007 in clone 10 : 38ng/µl
Bba_K1155007 in clone 14 : 48.5ng/µl
Bba_K1155007 in clone 15 : 52 ng/µl

CONCLUSION !!!!!!!! We will sequence our plasmid.

A - Aerobic/Anaerobic regulation system / B - PCB sensing system

Objective : Obtaining FNR and BphR2 proteins

1 - Electrophoresis of the PCR of BphR2 Part I, BphR2 Part II, RBS_BphR2 Part I, FNR Part I, FNR Part II, RBS_FNR Part I to check the gel purification
