[Microbiological aspects of fermenting chicken manure at various temperatures]. / Mikrobiologicheskie aspekty fermentatsii kurinogo pometa pri razlichnykh temperaturakh.

Mesophilic and thermophilic groups of methanogenic bacteria were found in untreated fowl manure. The thermophilic anaerobic fermentation of fowl manure leads to the development of both individual methanogens utilizing only some of the methane precursors, and syntrophic associations that are also able to utilize complex substrates. The selection of methanogenic bacteria during fowl manure anaerobic fermentation results in accumulation of thermophilic forms utilizing acetate and propionate.
