Among eight isolates, two strains (Mt1B3 and Mt1B8 T ) belonged to bacterial groups not yet cultured from the mouse intestine. Whereas strain Mt1B3 was identified as a member of the family Planococcaceae and is closely related to Sporosarcina species and Filibacter limicola DSM 13886 T , strain Mt1B8 T was a novel bacterium. Based on phylogenetic analysis, strain Mt1B8 T is a member of the family Coriobacteriaceae . The closest relatives with validly published names were Asaccharobacter celatus , Adlercreutzia equolifaciens (
