Description:
Salt and alkaline-tolerant actinomycete strain, YIM 90018T, was isolated from a saline and alkaline soil sample collected from Qinghai, China, and was then subjected to polyphasic taxonomy. Aerial hyphae of strain YIM 90018T were not produced on almost tested media except YIM 82# agar. Vegetative hyphae were abundant, developed well, and not fragmented. Straight or flexuous (Rectiflexibiles) spore chains. The strain grew well at 25% of MgCl2.6H2O and pH 10. All of these characters consistently assign the strain YIM 90018T to known species of the genus Streptomyces. Based on phylogenetic analysis of 16S rDNA, DNA-DNA hybridization, phenotypic characters and comparison with known species of the genus, strain YIM 90018T can be differentiated from all the validly described Streptomyces species. A novel species, Streptomyces sparsus sp. nov. is proposed. The type strain of the new species is YIM 90018T (CCTCC AA204019= DSM 41858T).
