Bacillus niabensis sp. nov., isolated from cotton-waste composts for mushroom cultivation.
A group of five bacilli, designated strains 4T12, 4T19(T), 5M45, 5M53 and 5T52, isolated from cotton-waste composts for mushroom cultivation, were examined. These strains were Gram-positive, aerobic, motile, spore-forming rods. 16S rRNA gene sequence analyses revealed that the isolates belonged to the genus Bacillus, showing the highest levels of similarity (approx. 96.6-96.9 %) with respect to Bacillus herbersteinensis DSM 16534(T). The values for DNA-DNA hybridization (approx. 85-96 %) among these five strains revealed that they belong to the same species. The major menaquinone present was MK-7 and the predominant cellular fatty acids were anteiso-C(15 : 0) (approx. 24.5-33.9 %) and C(16 : 0) (approx. 15.1-34.1 %). The DNA G+C contents were 37.7-40.9 mol%. On the basis of physiological, biochemical, chemotaxonomic and comparative genomic analyses, the five isolates represent a novel species of the genus Bacillus, for which the name Bacillus niabensis sp. nov. is proposed. The type strain is 4T19(T) (=KACC 11279(T) =DSM 17723(T)).
