| Abstract |
A Gram-stain-positive, aerobic bacterial strain, designated SL15-1T, was isolated from desert soil which was sampled from the rhizosphere of Ammopiptanthus mongolicus, Hangjin Banner, Ordos, Inner Mongolia, northern China. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain SL15-1T was clustered with Kribbella strains, sharing the highest similarity of 16S rRNA gene sequence (96.97 %) with Kribbella sandramycini DSM 15626T. Strain SL15-1T contained diphosphatidylglycerol, phosphatidylglycerol, phosphatidylcholine, an unknown phospholipid, an unknown lipid and two unknown aminophospholipids as the major polar lipids. MK-9(H4) was the predominant menaquinone, while anteiso-C15 : 0, iso-C16 : 0, C17 : 1ω8c and iso-C14 : 0 were the major cellular fatty acids. Its genomic DNA G+C content was 65.3 mol%. The results of physiological and biochemical tests allowed the discrimination of strain SL15-1T from its phylogenetic relatives. Kribbella deserti sp. nov. is therefore proposed with strain SL15-1T (=CGMCC 1.15906T=KCTC 39825T) as the type strain.
