Paenibacillus algicola sp. nov., a novel alginate lyase-producing marine bacterium

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 HB172198 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 ω11 c . 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 HB172198 T (=CGMCC 1.13583 T =JCM 32683 T ).
