摘要： A Gram-stain-variable, facultatively anaerobic, endospore-forming, rod-shaped bacterium, designated HB172198(T), was isolated from brown alga collected at Qishui Bay, Hainan, PR China. Phylogenetic analysis of 16S rRNA gene sequences indicated that strain HB172198(T) belonged to the genus Paenibacillus, and the closest phylogenetically related species was Paenibacillus lemnae NBRC 109972(T) (97.6% similarity). The other 16S rRNA gene sequence similarities were under 97.0%. The whole genome average nucleotide identity value between strain H6172198(T) and the closest type strain was 75.3% and the in silico DNA DNA hybridization value was 20.2%. The predominant isoprenoid quinone was menaquinone 7 and the major fatty acids were anteiso-C-15:0, C-16:0, anteiso-C-17:0, iso C-16:0 and C-16:1 omega 11C. The combined phylogenetic relatedness, phenotypic and genotypic features supported the conclusion that strain HB172198(T) represents a novel species of the genus Paenibacillus, for which the name Paenibacillus algicola sp. nov. is proposed. The type strain is H6172198(T) (=CGMCC 1.13583(T) =JCM 32683(T)).
