One-Carbon Metabolism by the Rumen Acetogen Syntrophococcus Sucromutans
The rumen acetogen Syntrophococcus sucromutans has an absolute requirement for an electron acceptor system to catabolize a variety of carbohydrates as electron donors 1. It can use the O-demethylation of lignin-derived methoxybenzenoids as electron acceptor system, with the corresponding hydroxybenzenoid, acetate and CO2 as products. Formate or a methanogen in coculture can serve as electron acceptor system. Acetate and CO2 are the only products, with methane for the coculture.
