Abstract
ABSTRACT
The oxidation of acetate to hydrogen, and the subsequent conversion of hydrogen and carbon dioxide to methane, has been regarded largely as a niche mechanism occurring at high temperatures or under inhibitory conditions. In this study, 13 anaerobic reactors and sediment from a temperate anaerobic lake were surveyed for their dominant methanogenic population by using fluorescent in situ hybridization and for the degree of acetate oxidation relative to aceticlastic conversion by using radiolabeled [2-
14
C]acetate in batch incubations. When
Methanosaetaceae
were not present, acetate oxidation was the dominant methanogenic pathway. Aceticlastic conversion was observed only in the presence of
Methanosaetaceae
.
