Shewanella spsand Geobacter sps are most important species in MFC but i guess the wont be able to utilize sucrose/glucose in wastewater. They mostly use acetate, pyruvate and lactate as carbon source. Are bacteria/concortia have been used but they are generally wireless and mediater less microbes giving less yield. You can try directly using wastewater as inoculum and geting your own consortia. Following two review might help

Hello Vignesh,

please have a look to our publication Hydrogen production in single chamber microbial electrolysis cells with different complex substrates, http://www.sciencedirect.com/science/article/pii/S0043135414007246

The first part deals about microbial consortia development for complex carbon sources treatment in MFC configuration. We used a mixture of anaerobic sludge and inoculum from a MFC to have a microbial community able to ferment different carbon sources to acetate/propionate that could be used by Geobacter.

We also applied this strategy for treating methanol in a previous paper http://www.sciencedirect.com/science/article/pii/S0360319913026669

I think that pure cultures for treating wastewater has very low interest due to its very low applicability in a real wastewater treatment.

Regards

Hello Vignesh,

Compared to pure cultures, it is beetr to use mixed consortia when you are considering wastewater as the substrate for the microbial fuels cells. collection of mixed culture from robust sources (treating high strength or high diverse waste/wastewater) will give you good performance. you can see the below that worked on the distillery based wastewater.

All the best

I would recommend Zymomonas culture.

Mixing culture is generally better than single strains. I would recommend an inoculum from a biogas plant. Regards

Methanogenesis is a microbial process, involving many complex, and differently interacting species, but most notably, the methane-producing bacteria. The extracellular enzymes of microbes, such as cellulase and amylase externally enzymolize organic material. Bacteria decompose the complex carbohydrates present in cellulosic sugarcane waste water. the facultatively anaerobic bacteria utilize oxygenand carbon, thereby creating the necessary anaerobic conditions necessary for methanogenesis.
