Gram-stain-negative rods. Growth of the strains was inhibited on medium containing 20 % bile. The two strains produced butyric and isobutyric acids as the end products from glucose, as has been observed in the other two species of the genus Butyricimonas. The major cellular fatty acid of strains 180-3(T) and 214-4(T) was iso-C15 : 0. The major menaquinone of the isolates was MK-10 (>50 %). Strains 180-3(T) and 214-4(T) have DNA G+C contents of 45 mol%. On the basis of these data, strains 180-3(T) and 214-4(T) represent two novel species of the genus Butyricimonas, for which the names Butyricimonas faecihominis sp. nov. and Butyricimonas paravirosa sp. nov., respectively, are proposed. The type strains of B. faecihominis and B. paravirosa are 180-3(T) ( = JCM 18676(T) = CCUG 65562(T)) and 214-4(T) ( = JCM 18677(T) = CCUG 65563(T)), respectively.
