Different temperature optima for methane formation when enrichments from Acid peat are supplemented with acetate or hydrogen



Different temperature optima for methane formation when enrichments from Acid peat are supplemented with acetate or hydrogen



Applied and Environmental Microbiology 48(2): 389-394



Laboratory studies of methane formation in peat samples from an acid subarctic mire in Sweden indicated the presence of a low-temperature-adapted methanogenic flora. Enrichment culture studies with ethanol, acetate, hydrogen, or a combination of these as substrate for methane formation provided evidence for the existence of two different methanogenic populations in the peat: one, unaffected by hydrogen and using acetate, with a temperature optimum at 20 degrees C; the other, oxidizing hydrogen, with a temperature optimum at ca. 28 degrees C.
