Colonies are circular, convex, entire and cream colored after incubation for 3 days on anaerobe basal medium at 30℃. In the API 20A system, positive reaction for esculin hydrolysis, acid production from salicin (weak), glycerol, D­cellobiose, D­rhamnose and D­trehalose. In the API 20A system, negative reaction for oxidase activity, indole formation, urease activity, gelatin hydrolysis and acid production from D­glucose, D­mannitol, D­lactose, sucrose, D­maltose, D­xylose, L­arabinose, D-mannose, D-melezitose, D-raffinose and D-sorbitol. Strain LPB0331 ( = NIBRBAC000503355) was isolated from the intestine of a laboratory mouse in Daejeon , Korea ( 36°23′56.11″N 127°23′41.76″E ).
