Symbols denote the presence (+) or absence (–) of all enzymes needed for hydrolysis to pyruvate or whether the substrate has been reported to be used (+) or not used (−) in the literature. NR denotes substrate utilization has not yet been reported for a particular strain.

¹Cellulose hydrolysis products have been limited to glucose and cellobiose and not higher order cellodextrins.

²Physiological data has not yet been reported for this strain.
