摘要： A Gram-stain-positive, facultatively anaerobic, endospore-forming, irregular rod-shaped bacterium, designated DB13260(T), was isolated from tropical rainforest soil in Jianfengling Nature Reserve in Hainan, China. The isolate was found to grow with 0-4% (w/v) NaCl, at 5-40 degrees C and pH 6.0-10.5, with an optimum of 0% NaCl, 30-37 degrees C and pH 8.5-9.0, respectively. The predominant isoprenoid quinone was menaquinone 7 (MK-7), and the major fatty acids were anteiso-C-15 (:) (0), iso-C-16 : 0 and C-16 : 0. The G+C content of the genomic DNA was 53.7 mol%. Analysis of the 16S rRNA gene sequence of strain DB13260(T) showed an affiliation of the strain with the genus Paenibacillus, sharing 98.3% and 97.8% 16S rRNA gene sequence similarities with the closest relatives Paenibacillus anaericanus MH21(T) and Paenibacillus selenii W126(T), respectively. The DNA-DNA hybridization values between strain DB13260(T) and the two type strains were 60.4% and 42.6 %, respectively. The combined phenotypic and DNA-DNA hybridization data supported the conclusion that strain DB13260(T) represents a novel species of the genus Paenibacillus, for which the name Paenibacillus segetis sp. nov. is proposed. The type strain is DB13260(T) (=CGMCC 1.12769(T) =DSM 28014(T)).
