sp. nov., isolated from the faecal material of a painted turtle.

A strict anaerobic, Gram-stain-positive rod-shaped bacterium, designated PT, was isolated from the faecal material of a painted turtle (). Based on a comparative 16S rRNA gene sequence analysis, the isolate was assigned to with the highest sequence similarities to (97.4 %), (97.2 %) and the misclassified organism (97.1 %). The predominant cellular fatty acids of strain PT were C, C and an unidentified product with an equivalent chain length of 14.969. The G+C content determined from the genome was 28.8 mol%. The fermentation end products from glucose were acetate and butyrate with no alcohols detected and trace amounts of CO and H also detected; no respiratory quinones were detected. Based on biochemical, phylogenetic, genotypic and chemotaxonomic criteria, the isolate represents a novel species of the genus for which the name sp. nov. is proposed. The type strain is strain PT (=CCUG 74180=ATCC TSD-219).
