Brochothrix, a New Genus Tentatively Placed in the Family Lactobacillaceae

Abstract
Microbacterium thermosphactum McLean and Sulzbacher differs to such an extent from the type species of Microbacterium, M. lacticum Orla-Jensen, that it cannot be retained in this genus. Recent studies have shown that M. thermosphactum strains form a distinct taxon worthy of genus status. A new genus, Brochothrix, is established for the species B. thermosphacta (McLean and Sulzbacher) comb. nov. This genus is tentatively placed in the family Lactobacillaceae. B. thermosphacta is the type species of the genus, and ATCC 11509 is designated to be the type strain of B. thermosphacta.
