title: Thermus rehai sp. nov., isolated from Rehai of Tengchong, Yunnan Province, China.
abstract: A yellow-pigmented strain of the genus Thermus, with optimum growth temperatures about 65 approximately 70 degrees C, was isolated from the hot springs in Rehai of Tengchong, Yunnan Province, China. Morphological, physiological and biochemical characteristics, pigment analysis of RH99-GF7504 strain and its phylogenetic analysis of 16S rDNA showed that this organism represented a new species of the genus Thermus. This strain had maximum temperatures for growth below 80 degrees C. The new isolate from Rehai of Tengchong could be distinguished from other strains of the genus Thermus by its special structure and by its inability to hydrolyze gelatin and starch. On the basis of phylogenetic analysis, morphological, physiological and biochemical characteristics, the name Thermus rehai sp nov is proposed for the species, represented by strain RH99-GF7504 (CCTCC-AB200292).
