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

A strict anaerobic, Gram-stain-positive rod-shaped bacterium, designated PT T , was isolated from the faecal material of a painted turtle ( Chrysemys picta ). Based on a comparative 16S rRNA gene sequence analysis, the isolate was assigned to Clostridium sensu stricto with the highest sequence simil...

Zusammenfassung:A strict anaerobic, Gram-stain-positive rod-shaped bacterium, designated PT T , was isolated from the faecal material of a painted turtle ( Chrysemys picta ). Based on a comparative 16S rRNA gene sequence analysis, the isolate was assigned to Clostridium sensu stricto with the highest sequence similarities to Clostridium moniliforme (97.4 %), Clostridium sardiniense (97.2 %) and the misclassified organism Eubacterium multiforme (97.1 %). The predominant cellular fatty acids of strain PT T were C 14 : 0 , C 16 : 0 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 2 and H 2 also detected; no respiratory quinones were detected. Based on biochemical, phylogenetic, genotypic and chemotaxonomic criteria, the isolate represents a novel species of the genus Clostridium for which the name Clostridium chrysemydis sp. nov. is proposed. The type strain is strain PT T (=CCUG 74180 T =ATCC TSD-219 T ).
