All of the strains grew on d-glucose as a sole carbon source (1 %, w/v) but were unable to degrade adenine, hypoxanthine, tyrosine or xanthine or to grow on d-cellobiose, d-sucrose (each at 1 %, w/v) or sodium acetate (0.1 %, w/v) as sole carbon sources
Data on the type strains were taken from Goodfellow and Maldonado (2012)
