Abstract
A Gram-stain-positive, facultatively anaerobic, endospore-forming, rod-shaped strain, AGMB 02131T, which grew at 20-40°C (optimum 30°C), pH 3.0-11.0 (optimum pH 4.0) and in the presence of 0-18% (w/v) NaCl (optimum 10%), was isolated from a cow faecal sample and identified as a novel strain using a polyphasic taxonomic approach. The phylogenetic analysis based on 16S rRNA gene sequences along with the whole genome (92 core gene sets) revealed that AGMB 02131T formed a group within the genus Peribacillus , and showed the highest sequence similarity with Peribacillus endoradicis DSM 28131T (96.9%), following by Peribacillus butanolivorans DSM 18926T (96.6%). The genome of AGMB 02131T comprised 70 contigs, the chromosome length was 4 038 965 bp and it had a 38.5% DNA G+C content. Digital DNA-DNA hybridization revealed that AGMB 02131T displayed 21.4% genomic DNA relatedness with the most closely related strain, P. butanolivorans DSM 18926T. AGMB 02131T contains all of the conserved signature indels that are specific for members of the genus Peribacillus . The major cellular fatty acids (>10%) of AGMB 02131T were C18:1 ω9c, C18:0 and C16:0. The major polar lipids present were diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine. On the basis of the phenotypic, phylogenetic, genomic and chemotaxonomic features, AGMB 02131T represents a novel species of the genus Peribacillus , for which the name Peribacillus faecalis sp. nov. is proposed. The type strain is AGMB 02131T (=KCTC 43221T=CCTCC AB 2020077T).
