Summary of "Peptostreptococcus russellii sp. nov., isolated from a swine-manure storage pit."

A polyphasic taxonomic study was performed on seven strains of an unknown Gram-positive, nonspore-forming, obligately anaerobic coccus-shaped bacterium isolated from a swine-manure storage pit. Comparative 16S rRNA gene sequencing confirmed that all these isolates were highly related to each other and formed a hitherto unknown linage within the clostridial rRNA XI cluster of organisms. Pairwise analysis demonstrated that the novel organism to be most closely related to Peptostreptococcus anaerobius and Peptostreptococcus stomatis with 16S rDNA gene sequence similarity values of 95.5% and 93.0%, respectively. The peptidoglycan type of the cell wall was determined to be A4α L-Lys-D-Asp with glucose, xylose and traces of mannose as the cell wall sugars. Based on biochemical, chemotaxomonic, and phylogenetic evidence it is proposed that the unknown bacterium be classified as a new species, Peptostreptococcus russellii sp. nov. The type strain is RT-10BT (=CCUG 58235T = NRRL B-59380T= DSM 23041T).
