Strictly anaerobic, carbohydrate fermenters 8. Some species are H2/CO2 utilizing acetogens 9 10. Autotrophic and/or heterotrophic growth is possible by some species through the metabolism of H2/CO2, and a variety of organic substrates, respectively 9 10 8 11 2. Acetate, formate, succinate, lactate and ethanol are produced as by products of fermentation 8 11 9 10 2. Cellulose is degraded by some species 11 6. Cells of Ruminococcus are coccobacilli, occurring in pairs or short chains 8 9 10. No in situ information is available for the genus in wastewater treatment systems.
