title: Streptomyces fuscichromogenes sp. nov., an actinomycete from soil.
abstract: A novel actinomycete, designated strain m16T, was isolated from a soil sample collected from the tropical rain forest of Xishuangbanna, a prefecture in Yunnan Province, south-west China, and characterized by using polyphasic taxomomy. Cells were aerobic and Gram-reaction-positive, and spore chains were observed to be of the helical type, with elliptical spores and smooth spore surfaces. The novel strain grew over a temperature range of 15-35 °C, at pH 5.0-11.0 and in the presence of 0-3 % (w/v) NaCl. The DNA G+C content of strain m16T was 70.0 mol%. The main fatty acids were iso-C16 : 0 (29.3 %), iso-C15: 0 (15.4 %) and anteiso-C15:0 (14.6 %), and the predominant menaquinones were MK-9(H6), MK-9(H8) and MK-9(H4). Comparative 16S rRNA gene sequence analysis showed that strain m16T was most closely related to Streptomyces jiujiangensis KCTC 29262T (98.7 %), Streptomyces panaciradicis KACC 17632T (98.7 %), Streptomyces rhizophilus NBRC 108885T (98.5 %), Streptomyces shenzhenensis DSM 42034T (98.4 %), Streptomyces graminisoli JR-19T (98.4 %) and Streptomyces gramineus JR-43T (98.3 %). Phylogenetic, chemotaxonomic and phenotypic analyses indicated that strain m16T represents a novel species within the genus Streptomyces, for which the name Streptomyces fuscichromogenes is proposed. The type strain is m16T (=CGMCC 4.7110T=KCTC 29195T).
