Abstract:
Strain NRRL B-23883 T was isolated from retail ground beef as part of a study on the genetic diversity of Clostridium perfringens . 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 Peptoniphilus and Anaerosphaera , 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 T shared the peptidoglycan type A4β, l -Orn– d -Glu with members of the genus Peptoniphilus . Further phenotypic analysis revealed that strain NRRL B-23883 T was able to utilize glycyl l -methionine as a sole carbon source, in contrast to other species of the genus Peptoniphilus . Therefore, it is proposed that the isolate represents a novel species, Peptoniphilus methioninivorax sp. nov.; the type strain is NRRL B-23883 T ( = DSM 22461 T ).
