Oscillibacter valericigenes Sjm18-20T (= NBRC 101213T)
Oscillibacter valericigenes Sjm18-20T (= NBRC 101213T) is a mesophilic, strictly anaerobic bacterium isolated from the alimentary canal of a Japanese corbicula clam (Corbicula japonica) in Shimane Prefecture. Based on 16S rRNA gene sequences, the strain was revealed belonging to the clostridial cluster IV, one of the 19 clusters of clostridial bacteria. Clostridial cluster IV is known to contain phenotypically heterogeneous bacteria. O. valericigenes was shown to be distant from any other species of clostridial cluster IV in 16S rRNA sequence analysis. Instead, it was most similar to the large cells mechanically enriched from sheep rumen contents and thought to represent "Oscillospira guilliermondii", which was originally reported in as early as 1913.
The genome sequence of strain Sjm18-20 revealed one circular chromosome (4,410,036 bp, 53.32 % G+C, 4,656 ORFs, 3 rRNA operons, 58 tRNA genes) and one circular plasmid (60,586 bp, 43.33% G+C, 67 ORFs). The genome sequence of the strain would provide clues about the lifecstyle and the isolation of related and uncultivated bacteria.
