Milestones

  • Initiating lab work on the sub-project endogenous mediator Glycerol dehydrogenase.
  • Starting lab work with the first successful PCR: gldA with pre- and suffix overlaps could be amplified from Escherichia coli genome.
  • The main work however is still planning of our sub-projects, designing experiments and a lot of research.
  • Finding sponsors goes ahead. Many companies like our project and want to support us.
  • MFC: We built a first prototype of a microbial fuel cell and tested it with different chemicals, baker’s yeast and the E. coli KRX wild type strain. Tested if methylene blue and neutral red are suitable as redox mediators for our system.




Week 1

Organization

  • We were already able to find sponsors for our team: IIT BIEKUBA, IIT Biotech, Evonik, PlasmidFactory and FisherScientific will support us.


MFC

  • Borrowed 2 multimeters from the faculty of physics.

Mediators

  • Glycerol dehydrogenase
    • Primerdesign for isolation of gldA gene from Escherichia coli KRX strain, with overlaps for BioBrick prefix and suffix:
    • Forward primer gldA (43 bp): GAATTCGCGGCCGCTTCTAGATGGACCGCATTATTCAATCACC
    • Reverse primer gldA (45 bp): CTGCAGCGGCCGCTACTAGTATTATTCCCACTCTTGCAGGAAACG





Week 2

Organization

  • Distribution of our team in various subgroups for best work efficiency.
  • We’ve organized a barbecue to thank the working group of Dr. Jörn Kalinowski in the CeBiTec for the appropriation of space and support in the laboratory.


MFC

  • Constructed a first prototype of a fuel cell out of two film canisters connected with a fragment of a centrifugation tube.




Week 3

Organization

  • Planning the trip to the European jamboree in Lyon from October 11th to 13th, 2013.


MFC

  • Experimented with with the film canister fuel cell using yeast as a biocatalyst.

Mediators

  • Glycerol dehydrogenase


Table 1: Standard phusion PCR master mix.

Table 2: Two step standard phusion PCR program for gldA amplification.


    • The gldA PCR product was isolated by agarose gel electrophoresis and purified.
    • Bands are on at the expected size of 1050 bp.

As a ladder we used [http://www.thermoscientificbio.com/nucleic-acid-electrophoresis/generuler-1-kb-dna-ladder-ready-to-use-250-to-10000-bp GeneRuler™ 1 kb DNA Ladder from Thermo Scientific].




Week 4

Organization

  • We will also take part at the congress ‘‘Next generation of biotechnological processes 2020+‘‘ in Berlin on June 27th, 2013.
  • Having a second presentation at Merck KGaA head office in Darmstadt for explaining our project in detail. We are happy that Merck will be our next supporter in 2013.

MFC

  • Tested if methylene blue and neutral red can work as redox mediators in our system.
