Je. Schmidt et Bk. Ahring, INTERSPECIES ELECTRON-TRANSFER DURING PROPIONATE AND BUTYRATE DEGRADATION IN MESOPHILIC, GRANULAR SLUDGE, Applied and environmental microbiology, 61(7), 1995, pp. 2765-2767
Granules from a mesophilic upflow anaerobic sludge blanket reactor wer
e disintegrated, and bacteria utilizing only hydrogen or formate or bo
th hydrogen and formate were added to investigate the role of interspe
cies electron transfer during degradation of propionate and butyrate.
The data indicate that the major electron transfer occurred via inters
pecies hydrogen transfer, while interspecies formate transfer may not
be essential for interspecies electron transfer in this system during
degradation of propionate and butyrate.
