Abstract
An obligate anaerobic, Gram-stain-positive, non-spore forming, non-motile, catalase and oxidase-negative, coccoid-shaped bacterium designated AGMB00486T was isolated from swine faeces. The optimal growth of the isolate occurred at pH 8.0 and 37 ℃. Furthermore, the growth was observed in the presence of up to 4% (w/v) NaCl but not at salinity levels higher than 5%. The phylogenetic analysis based on the 16S rRNA gene sequences revealed that strain AGMB00486T was a member of the genus Anaerococcus and that the isolate was most closely related to Anaerococcus vaginalis KCTC 15028T (96.7% 16S rRNA gene sequence similarity) followed by Anaerococcus hydrogenalis KCTC 15014T (96.7%) and Anaerococcus senegalensis KCTC 15435T (96.3%). Whole-genome sequence analysis determined that the DNA G+C content of strain AGMB00486T was 30.1 mol%, and the genome size, numbers of tRNA and rRNA genes were 2,268,866 bp, 47 and 8, respectively. The average nucleotide identity values between strain AGMB00486T and the three related type strains were 77.0, 77.4 and 77.2%, respectively. The major cellular fatty acids (> 10%) of strain AGMB00486T were C14:0, C16:0 and C16:0 DMA. Accordingly, these distinct phenotypic and phylogenetic properties revealed that strain AGMB00486T represents a novel species, for which the name Anaerococcus faecalis sp. nov. is proposed. The type strain is AGMB00486T (= KCTC 15945T = CCTCC AB 202009T).
