Hi Muhammad, if you read up on syntrophy you can easily undersrand the concept behind Direct Interspecies Electeon Transfer (DIET). Classically, syntrophic electron carriers were though to be small molecules such as formate or hydrogen. Recent models of electron transport in AD systems have proposed a more direct means of electron transport such as direct cell-cell contact through conductive appendages and iron oxides have been suggested to play a role too. It' a pretty intereting process and as well as biogas production and AD, similar processes occur in microbial metal reduction.

Hi Jamie Hinks

Thanks for the explanation. But my query is how magnetite nanoparticles increase biogas production by playing a role as a carrier in interspecies electron transfer? Or simply, you can say that how magnetite naniparticles increase biogas production?

Hi Philip Antwi,

Thanks a lot for sharing such a useful article. I got all my queries answered in this article.
