sp. nov., isolated from rhizosphere soil of Free

Abstract

A Gram-stain-negative, oval-shaped and light pink pigmented bacterium, designated XAAS-2, was isolated from rhizosphere soil of . The sole respiratory quinone of the type strain XAAS-2 was MK-7, and the principal cellular fatty acids were summed feature 4 (iso-C I and/or anteiso-C B) and iso-C. The major polar lipids were phosphatidylethanolamine and two unidentified lipids. 16S rRNA gene sequence analysis indicated that strain XAAS-2 belonged to the genus within the family with sequence similarities of 93.9–97.1 % to other type species of the genus and to CCTCC AB 207200 as the closest neighbour. The DNA G+C content of strain XAAS-2 was 50.6 mol%. The level of DNA–DNA relatedness of XAAS-2 and CCTCC AB 207200 was 47.5 % (=3.27). Phenotypic and genotypic data suggested that strain XAAS-2 represents a novel species of the genus , for which the name sp. nov. is proposed, with the type strain XAAS-2 (=CCTCC AB 2016135=JCM 31443).
