A Gram-stain-variable, motile, aerobic, spore-forming, rod-shaped bacterium, designated as strain LOB 377T, was isolated from soil sampled in Koka County (now Konan City), in Shiga Prefecture, Japan. To determine its taxonomic position, the bacterium was evaluated by a polyphasic approach based on genomic, phenotypic and chemotaxonomic tests. From phylogenetic analysis based on 16S rRNA gene sequences, strain LOB 377T (LC570960) was revealed to have the highest similarity to the type strain of Neobacillus mesonae FJAT-13985T (9.1 %). The average nucleotide identity and digital DNA–DNA hybridization values between both strains based on whole genome sequences were 84.1 and 42.8 %, respectively, which were below the recommended thresholds. The strain grew at 15–45 °C (optimum, 25–37 °C), at pH 5.5–9.5 (optimum, pH 6.5–8.5) and with 1.0–2.0 % (w/v) NaCl. Cell-wall peptidoglycan of the strain contained meso-diaminopimelic acid. The major menaquinone was menaquinone-7. Predominant fatty acids were iso-C15 : 0, anteiso-C15 : 0, iso-C14 : 0 and C16 : 1 ω11c. The polar lipids were phosphatidylglycerol, unidentified phospholipid and unidentified aminophospholipid. The DNA G+C content was 40.5 mol%. According to the genomic, phenotypic and chemotaxonomic results, strain LOB 377T represents a novel species in the genus Neobacillus , for which the name Neobacillus kokaensis sp. nov. is proposed. The type strain is LOB 377T (=ATCC 31382T=NBRC 114637T=DSM 113418T).
