Abstract

A novel themophilic bacterium, designated YIM 79486, was isolated from a sediment sample collected from Jinze hot spring in Tengchong county, Yunnan province, south-west China. Phylogenetic analysis based on 16S rRNA gene sequence analysis revealed that strain YIM 79486 should be assigned to the genus and formed a monophyletic clade with the type strain KCTC 3666 (98.7 % similarity). Strain YIM 79486 formed white aerial mycelium and brown substrate mycelium. Abundant endospores were produced on short sporophores. Cell-wall peptidoglycan contained -diaminopimelic acid. The predominant menaquinones were MK-9 and MK-8. The genomic DNA G+C content observed for strain YIM 79486 was 47.8 mol%. Based on low DNA–DNA hybridization data, chemotaxonomic characteristics and differential physiological properties, strain YIM 79486 is considered to represent a novel species within the genus , for which the name sp. nov. is proposed. The type strain is YIM 79486 (=CCTC AB 2015040=NBRC 110772).
