Abstract:
A Gram-positive, non-motile actinobacterium, designated strain YIM 70177 T , was isolated from a saline soil sample from Qinghai Province, north-west China. Phylogenetic analysis of this organism based on 16S rRNA gene sequences revealed 98·3 % similarity to Isoptericola variabilis DSM 10177 T . Chemotaxonomic data determined for the isolate, such as the peptidoglycan type A4 α , variation l -lys– d -Asp, supported the placement of strain YIM 70177 T within the genus Isoptericola . Galactose was detected as cell wall sugar. Phospholipids identified were phosphatidylinositol, phosphatidylglycerol and diphosphatidylglycerol, and the predominant menaquinones were MK-9(H 4 ) and MK-9(H 2 ). The major fatty acids were ai-C 15 : 0 , C 16 : 0 , ai-C 17 : 0 and i-C 15 : 0 . The DNA G+C content was 72·8 mol%. The low level of DNA–DNA relatedness (27·4 %) to I. variabilis DSM 10177 T in combination with differentiating chemotaxonomic and physiological data demonstrated that the isolate YIM 70177 T should be classified as representing a novel species of the genus Isoptericola . The name Isoptericola halotolerans sp. nov. is proposed, with strain YIM 70177 T (=DSM 16376 T =KCTC 19046 T ) as the type strain.
