Discuss, in terms of energy yields of the appropriate reactions, the importance of the syn-trophic relationship between acetogens and methanogens, specifically the interspecies hydrogen transfer. If, in the absence of other electron acceptors, methanogenesis is inhibited, what impact would this have on the carbon cycle ...

Protozoa hydrolysed carbohydrate to produce hydrogai which then be used directly by associated methanogens to produce methane. Ushida et al. (1997) showed the occurrence of interspecies hydrogen transfer between the rumen ciUate Polyplastron multivesiculatum and the methanogenic archebacterium, Methanosarcina barkeri. Therefore, reducing protozoa will also reduce ruminal methanogens, thus reducing methane production. Tables 11.1 and 11.2 show that the studies mostly reported the...

Other self-produced compounds for exocellular electron transfer. In addition to electron transfer by nanowires and endogenous mediators like pyocyanin, electron transfer can also occur through interspecies hydrogen transfer, the production of intermediate metabolites such as formate and acetate and other chemicals. An overall review of this subject is provided by Stams et al. (2006). However, here the focus is on direct electron transfer and thus these other routes of interspecies chemical transfer will not be addressed.
