Dyadobacter alkalitolerans sp. nov., isolated from desert sand

College of Life Sciences, Wuhan University, Wuhan 430072, PR China Correspondence Chengxiang Fang cxfang{at}whu.edu.cn A polyphasic taxonomic approach was used to study strain 12116 T , which was isolated from desert sand in Xinjiang, China. Cells of the isolate were Gram-negative, non-motile, rod-shaped and aerobic. MK-7 was the predominant respiratory menaquinone. The DNA G+C content was 46.3 mol%. A phylogenetic analysis based on 16S rRNA gene sequences showed that the isolate was most closely related to the members of the genus Dyadobacter , with similarities ranging from 94.7 to 96.6 %. Therefore, on the basis of genotypic and phenotypic data, strain 12116 T represents a novel species of the genus Dyadobacter , for which the name Dyadobacter alkalitolerans sp. nov. is proposed. The type strain is 12116 T (=CCTCC AB 207176 T =NRRL B-51268 T ). The GenBank/EMBL/DDBJ accession number for the 16S rRNA gene sequence of strain 12116 T is EU360597 .
