sp. nov., isolated from a saline and alkaline soil Free

Abstract

A salt- and alkali-tolerant actinomycete strain, YIM 90018, was isolated from a saline and alkaline soil sample collected from Qinghai, China. Aerial hyphae of strain YIM 90018 were only produced on YIM 82 agar. Vegetative hyphae were well developed and did not fragment. Straight or flexuous () spore chains were produced. The isolate grew well with 25 % (w/v) MgCl . 6HO and at pH 10. All of these characters indicated that strain YIM 90018 belonged to the genus . On the basis of phylogenetic analysis of the 16S rRNA gene sequence, DNA–DNA hybridization and phenotypic characteristics, strain YIM 90018 could be differentiated from all recognized species of the genus . A novel species, sp. nov., is proposed, with strain YIM 90018 ( = CCTCC AA204019 = DSM 41858) as the type strain.
