Title Bacillus pinisoli sp. nov., Isolated from Soil of a Decayed Pine Tree.
Journal Curr Microbiol
Abstract A Gram-stain-positive, rod-shaped, facultatively anaerobic, motile and spore-forming bacterium with multiple flagella designated GXH0341T was isolated from the soil associated with decayed pine tree samples collected from Weizhou Island, Beihai, Guangxi, China. Growth occurred at 4-37 °C (optimum 30 °C), at pH 5.0-11.0 (optimum 8.0) and in the presence of 0-7% (w/v) NaCl (optimum 2%). Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain GXH0341T was most closely related to Bacillus mesophilus DSM 101000 T (98.9%), followed by Bacillus salitolerans KC1T (96.95%) and Margalitia shackletonii DSM 18435 T (96.67%). Phylogenetic analysis revealed that strain GXH0341T represented a separate lineage within the genus Bacillus. Peroxidase is positive. The predominant quinone was MK-7 and the cell-wall diagnostic diamino acid was meso-diaminopimelic acid. The predominant polar lipids are diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylcholine, and two unidentified phospholipids. The major fatty acids are iso-C14:0, iso-C15:0, anteiso-C15:0 and iso-C16:0. The genome of GXH0341T comprises the biosynthetic gene cluster for T3PKS, terpene, lassopeptide and RRE-containing element as secondary metabolites. The average nucleotide identity values and the digital DNA-DNA hybridization values between GXH0341T and B. mesophilus DSM 101000 T were 78.22% and 21.00%, respectively, which were in the range of the recommended level for interspecies identity. The results of phenotypic, chemotaxonomic and genotypic analyses clearly indicated strain GXH0341T represents a novel species of the genus Bacillus, for which the name Bacillus pinisoli sp. nov. is proposed. The type strain is GXH0341T (= MCCC 1K07157T = JCM 35212 T).
