Abstract
A Gram-positive bacterium, designated strain XY18T, was isolated from a cured vanilla bean in Hainan province, China. Cells were rod-shaped, endospore producing, and peritrichous flagella. Strain XY18T grew at salinities of 0–8 % (w/v) NaCl (optimally 1–4 %), pH 4.0–8.0 (optimally 5.0–7.0 %) and temperature range 20–45 °C (optimally 28–35 °C). The predominant menaquinone was MK-7. The major cellular fatty acids were anteiso-C15:0, iso-C15:0, anteiso-C17:0, and iso-C17:0. Phylogenetic analysis based on 16S rRNA gene sequence indicated that strain XY18T was a member of the genus Bacillus, and closely related to B. amyloliquefaciens NBRC 15535T and B. siamensis PD-A10T, with 99.1 and 99.2 % sequence similarity, respectively. However, the DNA–DNA hybridization value between strain XY18T and B. amyloliquefaciens NBRC 15535T was 35.7 %. The genomic DNA G+C content of strain XY18T was 46.4 mol%, significantly differed from B. siamensis PD-A10T (41.4 %), which was higher than the range of 4 % indicative of species. On the basis of polyphasic taxonomic study, including phenotypic features, chemotaxonomy, and phylogenetic analyses, strain XY18T represents a novel species within the genus Bacillus, for which the name Bacillus vanillea sp. nov. is proposed. The type strain is XY18T (=CGMCC 8629 = NCCB 100507).
