Interspecies hydrogen transfer between the rumen ciliate Polyplastron multivesiculatum and Methanosarcina barkeri (original) (raw)

This study investigates the interspecies hydrogen transfer between the rumen ciliate Polyplastron multivesiculatum and the methanogen Methanosarcina barkeri. Using long-term co-culturing, the researchers explore the effects of this interaction on feed degradation and metabolic activity in vitro. The findings demonstrate a significant reduction in hydrogen and formate production by P. multivesiculatum in the presence of M. barkeri, leading to increased methane, acetate, and propionate production, along with enhanced apparent dry matter disappearance.
