A Win-Loss Interaction on Fe⁰ Between Methanogens and Acetogens From a Climate Lake.

ABSTRACT: Diverse physiological groups congregate into environmental corrosive biofilms, yet the interspecies interactions between these corrosive physiological groups are seldom examined. We, therefore, explored Fe⁰-dependent cross-group interactions between acetogens and methanogens from lake sediments. On Fe⁰, acetogens were more corrosive and metabolically active when decoupled from methanogens, whereas methanogens were more metabolically active when coupled with acetogens. This suggests an opportunistic (win-loss) interaction on Fe⁰ between acetogens (loss) and methanogens (win). Clostridia and Methanobacterium were the major candidates doing acetogenesis and methanogenesis after four transfers (metagenome sequencing) and the only groups detected a
