This could be the reason why there was an increase in microbial diversity in the cathodic biofilm. In another study, the use of two different electron acceptors in the cathodic compartment was reported for the very first time Zhang, B. Samples were collected from anodic and cathodic samples, and planktonic culture. This may be due to the presence of an evolving bacterial population in the anodic chamber that reached the equilibrium after weeks of operation.
It is clear from the figure that the nitrogen-doped graphene nanosheets show the best catalytic activity compared to other materials. Please select author name in each record!
