Buy 300ml each chamber big MFC, buy multimeter, stainless steel, enameled wire. Buy PEM(proton exchange membrane) membrane and use H2O2 and H2SO4 boiled solution handle the PEM.
first appliance, and it is the biggest one. We use it and incubate a PNP endurance bacteria named LZU-3.We hoped that LZU-3 could degrade potassium dichromate, but we failed.
April/June 2014
We prepared anode medium and cathode medium, incubate the Pseudomonas aeruginosa and Shewanella oneidensis and LZU-3. Testing the big MFC devices and collected the data.
July 2014
We tried to research how dose PNP influence the MFC power output. We buy 4 others MFC devices from internet, and prepare PEM carbon brush for it.
August 2014
We designed our own device and tried our best to manufacture the new MFC. We tested the performance of these 11 MFC devices. Different sizes(from 160*160*80 mm to 25*25*25 mm) were used in our experiment. At last we found that 50*50*50 mm is the best size of this battery.
In September and October, we run our MFCs and gain a lot of data, we tried to figure out, dose riboflavin can stimulate the MFC power output, and, how accuracy did the genetically engineered E.coli response to the PNP concentration. we worked out empirical curves about the relationship between PNP concentration and output voltage.
We also measured the riboflavin expression data of the genatically modified E.coli.
