Abstract:
:An alkalitolerant actinomycete strain, designated EGI 80674T, was isolated from a rhizosphere soil of Halocnermumstrobilaceum (Pall.) Bieb in Xinjiang, north-west China and subjected to a taxonomic characterization using a polyphasic approach. Strain EGI 80674T formed white aerial hyphae with long spore chains. Whole-cell hydrolysates of the isolate contained meso-diaminopimelic acid as the diagnostic diamino acid with no diagnostic sugars. The major fatty acids identified were iso-C16 : 0, anteiso-C17 : 0 and 10-methyl-C18 : 0TBSA. The predominant menaquinones detected were MK-10(H8) and MK-10(H6). The G+C content of the genomic DNA of strain EGI 80674T was 70.9 mol%. Strain EGI 80674T showed the highest 16S rRNA gene sequence similarity (97.24 %) to Nocardiopsis nikkonensis NBRC 102170T. The DNA-DNA relatedness value of strain EGI 80674T and N. nikkonensis NBRC 102170T was 18.4±1.3 %. Phenotypical, chemotaxonomic and phylogenetic characteristics and DNA-DNA hybridization data suggest that strain EGI 80674T represents a novel species of the genus Nocardiopsis, for which the name Nocardiopsis rhizosphaerae sp. nov. is proposed. The type strain is EGI 80674T (=CGMCC 4.7228T=KCTC 39673T).
