title: Saccharopolyspora qijiaojingensis sp. nov., a halophilic actinomycete isolated from a salt lake.
abstract: A halophilic actinomycete strain, designated YIM 91168T, was isolated from a salt lake in Xinjiang province, north-west China. The isolate grew at 20-40 degrees C, pH 5-8 and 6-22% (w/v) NaCl; there was no growth in the absence of NaCl. The whole-cell hydrolysate contained meso-diaminopimelic acid, galactose and arabinose. The major fatty acids were iso-C15:0, iso-C16:0 and iso-C17:0. MK-9(H4) was the predominant menaquinone and the genomic DNA G+C content was 70.1 mol%. These chemotaxonomic data, together with its morphological properties, were consistent with the assignment of strain YIM 91168T to the genus Saccharopolyspora. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain YIM 91168T had highest sequence similarity (95.4%) with Saccharopolyspora gregorii NCIB 12823T, and showed lower 16S rRNA gene sequence similarity (93.0-95.1%) with the other species of the genus Saccharopolyspora. On the basis of evidence from this polyphasic study, the novel species Saccharopolyspora qijiaojingensis sp. nov. is proposed. The type strain is YIM 91168T (=DSM 45088T=KCTC 19235T).
