N2 - A Gram-stain positive, endospore-forming, circular, convex, cream colored, designated strain 18JY8-7T, was isolated from soil collected in Jeju Island, South Korea. Phylogenetic analysis using 16S rRNA gene sequences showed that strain 18JY8-7T formed a distinct lineage within the family Paenibacillaceae (order Bacillales, class Bacilli), and is closely related to Cohnella rhizosphaerae (96.1%, sequence similarity) and Cohnella xylanilytica (96.0%). Optimal growth occurred at 30 °C, pH 6.5 and in the absence of NaCl. The predominant cellular fatty acids were anteiso-C15:0 and iso-C16:0. The major respiratory quinone was MK-7. The polar lipids profile comprised of diphosphatidylglycerol, phosphatidylglycerol, and phosphatidylethanolamine. The DNA G + C content was 57.0 mol %. The genotypic and phenotypic analyses revealed the differentiation of strain 18JY8-7T from all recognized Cohenella species. The strain 18JY8-7T, therefore represents a novel bacterial species within the family Paenibacillaceae, for which the name Cohnella candidum sp. nov. is proposed. The type strain is 18JY8-7T (= KCTC 33969T = JCM 33199T).
