Abstract

A Gram-stain-negative, yellow, motile by gliding, filamentous bacterium, designated SR 2-06, was isolated from surface-sterilized root of garden cosmos. 16S rRNA gene sequence analysis indicated that SR 2-06 was related most closely to YT21 of the family at a sequence similarity of 96.90 %, while levels of similarity to other related taxa were less than 93.08 %. Strain SR 2-06 exhibited similar features to in that it contained MK-7 as the major respiratory quinone, and iso-C G, iso-C and a summed feature consisting of Cω6 and/or Cω7 as the major fatty acids. However, strain SR 2-06 was distinguished from using a combination of physiological and biochemical properties. The cellular polar lipids were phosphatidylethanolamine, unknown aminophospholipids, unknown aminolipids, an unknown phospholipid and unidentified polar lipids. The DNA G+C content was 46.0 mol%. The phenotypic and phylogenetic evidence clearly indicates that strain SR 2-06 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is SR 2-06 ( = KCTC 42060 = JCM 19844).
