sp. nov., isolated from soil from an arid area, and emended descriptions of the genus and Free

Abstract

A Gram-reaction-negative, rod-shaped, gliding and brightyellow-pigmented bacterial strain, designated JCN-23, was isolated from a soil sample collected from an arid area in Gansu Province in north-west China, and characterized by using a polyphasic taxonomic approach. This isolate grew optimally at 30 °C and in the absence of NaCl. The only respiratory quinone was menaquinone-7 and the major cellular fatty acids were iso-C, iso-C 3-OH, summed feature 9 (iso-Cω9 and/or C 10-methyl) and summed feature 3 (Cω7 and/or Cω6). The only polyamine was homospermidine and the major polar lipid was phosphatidylethanolamine. The DNA GC content was 47.1 mol%. Comparative 16S rRNA gene sequence analysis showed that strain JCN-23 was a member of the phylum , exhibiting the highest 16S rRNA gene sequence similarity to CCTCC AB 208255 (97.6 %). No other recognized bacterial species showed more than 93.4 % 16S rRNA gene sequence similarity to the novel isolate. DNA–DNA hybridization experiments showed a low level (26 %) of DNA–DNA relatedness between strain JCN-23 and CCTCC AB 208255. On the basis of the phenotypic and genotypic data and phylogenetic inference, strain JCN-23 is considered to represent a novel species of the genus , for which the name sp. nov. is proposed. The type strain is JCN-23 ( = ACCC 05418 = KCTC 23071). Emended descriptions of the genus and are also proposed.
