Paenibacillus albus sp. nov., a UV radiation-resistant bacterium isolated from soil in Korea

A novel Gram-stain-positive, motile, white color and endospore-forming bacterium, designated 18JY67-1^T, was isolated from soil in Jeju Island, Korea. The strain grow at 15–42 °C (optimum 30 °C) in R2A medium at pH (6.0–9.5) (optimum 7.5). Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain 18JY67-1^T formed a distinct lineage within the family Paenibacillaceae (order Bacillales, class Bacilli), and was closely related to Paenibacillus rhizoryzae (KP675984; 96.9% 16S rRNA gene sequence similarity). The major cellular fatty acids of the strain 18JY67-1^T were C_16:0 and anteiso-C_15:0. The predominant respiratory quinones were MK-7. The major polar lipid was identified as diphosphatidylglycerol. On the basis of phenotypic, chemotaxonomic and genotypic properties clearly indicated that isolate 18JY67-1^T represents a novel species within the genus Paenibacillus, for which the name Paenibacillus flavus sp. nov. is proposed. The type strain of Paenibacillus flavus is 18JY67-1^T (= KCTC 33959^T = JCM 33184^T).
