Abstract

Methanogens, reductive acetogens and sulfate-reducing bacteria play an important role in disposing of hydrogen in gut ecosystems. However, how they interact with each other remains largely unknown. This study cocultured (reductive acetogen), (sulfate reducer) and (methanogen). Results revealed that these three species coexisted and did not compete for hydrogen in the early phase of incubations. Sulfate reduction was not affected by and . inhibited the growth of and after 10 h incubations, and the inhibition on was associated with increased sulfide concentration. Remarkably, growth lag phase was shortened by coculturing with and . Formate was rapidly used by under high acetate concentration. Overall, these findings indicated that the interactions of the hydrogenotrophic microbes are condition-dependent, suggesting their interactions may vary in gut ecosystems.
