Hi, I'm a student, very new in this field and I need some clarification.
From the literature that I have read:
(i) it states that single chambered MFC produces higher power density than a dual-chambered MFC. However, there are still lots of study/research conducted using a dual-chambered MFC. What are the advantages and disadvantages of each type of design? (ii) most of the studies used PEM Nafion 117 type of membrane. Why is it so? Thank you.

Lets assume we are taking LB broth for medium. Will this affect the transfer of electrons?

Hi,
I have read that, a bacteria in its natural conditions, when it transfer electrons to the external acceptors, energy is produced in the form of ATP, due to the inward flow of protons. But, in a BES, when the anode accept the electons from the bacteria:
- does any proton flow occur into the bacterial cell?
- Is ATP produced? if yes, how are they produced?

I am a student of biotechnology doing my final year project on microbial fuel cells.
Can I use Agar Salt Bridge (Sodium nitrate, agar, water (15g:3g:150mL)) instead of proton exchange membrane?

Good Afternoon Madams and Sir's. I'm John, an undergraduate student. I have red the study on Microbial Fuel Cells and I used it as one of my References for my undergrad Thesis.
I have constructed a two chambered MFC and tried to run it and record the voltage. Unfortunately, the digital multi meter gave me a negative reading w/c means that the phosphate buffer in the cathode chamber was the one that produced the electricity instead of the waste water in the anode.
I have constructed it properly and used the multi meter properly also as stated in the procedure that I got from the internet w/c I have attached with this massege . Please help advise me what to do for I need to finish it before the end of february.
Thank you!
