sp. nov., an actinomycete from soil Free

Abstract

A novel actinomycete, designated strain m16, 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 m16 was 70.0 mol%. The main fatty acids were iso-C (29.3 %), iso-C (15.4 %) and anteiso-C (14.6 %), and the predominant menaquinones were MK-9(H), MK-9(H) and MK-9(H). Comparative 16S rRNA gene sequence analysis showed that strain m16 was most closely related to KCTC 29262 (98.7 %), KACC 17632 (98.7 %), NBRC 108885 (98.5 %), DSM 42034 (98.4 %), JR-19 (98.4 %) and JR-43 (98.3 %). Phylogenetic, chemotaxonomic and phenotypic analyses indicated that strain m16 represents a novel species within the genus , for which the name is proposed. The type strain is m16 (=CGMCC 4.7110=KCTC 29195).
