Abstract

Strain NRRL B-23883 was isolated from retail ground beef as part of a study on the genetic diversity of . The strain was found to be a strictly anaerobic, Gram-positive coccus that was able to utilize peptone as a sole carbon source. Analysis of the 16S rRNA gene sequence revealed that the strain was closely related to species within the genera and , but it was substantially different from the closest recognized species by nearly 10 % sequence divergence. The strain was also found to be closely related (>99 % sequence similarity) to an uncultured bacterial strain that was sequenced from a 16S rRNA gene clone library constructed to characterize the bacterial community of faeces from a captive spotted hyena. Strain NRRL B-23883 shared the peptidoglycan type A4β, -Orn–-Glu with members of the genus . Further phenotypic analysis revealed that strain NRRL B-23883 was able to utilize glycyl -methionine as a sole carbon source, in contrast to other species of the genus . Therefore, it is proposed that the isolate represents a novel species, sp. nov.; the type strain is NRRL B-23883 ( = DSM 22461).
