Abstract

A facultatively anaerobic, endospore-forming bacterium, designated strain P11-6, was isolated from soil of a ginseng field located in Geumsan County, Republic of Korea. Cells of strain P11-6 were Gram-stain-negative, catalase-negative, motile rods and produced semi-translucent, circular, white colonies on tryptic soy agar. The isolate contained MK-7 as the only menaquinone and anteiso-C as the major fatty acid. Diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, an unknown aminophosphoglycolipid, an unknown aminophospholipid, two unknown phospholipids, three unknown glycolipids and three unknown lipids were detected in the polar lipid profile. The DNA G+C content of strain P11-6 was 41.9 mol%. Phylogenetic analysis based on 16S rRNA gene sequencing showed that strain P11-6 was most closely related to GPTSA 19 (97.2 % sequence similarity) and that it formed a separate lineage with in the family . Combined phenotypic and DNA–DNA hybridization data supported the conclusion that strain P11-6 represents a novel species in the genus , for which the name sp. nov. is proposed; the type strain is P11-6 (=KCTC 13564 =CECT 7605).
