Clostridium phytofermentans [1] (also called Lachnoclostridium phytofermentans) is an obligately anaerobic rod-shaped spore-forming, Gram-positive bacterium in the family Lachnospiraceae. It is a model organism of interest for its ability to ferment diverse plant polysaccharides [2] including cellulose, hemicellulose, and pectin to ethanol, acetate, and hydrogen. The C. phytofermentans 4.8 Mb genome has been fully sequenced,[3] revealing it contains over 170 enzymes in the CAZy database, though one hydrolase appears to be essential for degrading cellulose.[4]

This species is one of the many phylogenetically-problematic members of Clostridium. Yutin and Galperin proposed in 2013 to move it to its own genus Lachnoclostridium under Lachnospiraceae, but the publication was not validated under the Prokaryotic Code.[5] GTDB concurs with the assignment.[6]
