Abstract
Two novel bacteria, with an optimum growth temperature of approximately 60 °C, were isolated from Lu-shan hot springs in the central region of Taiwan. These isolates were aerobic, thermophilic, halotolerant, pink-pigmented, heterotrophic and resistant to gamma-radiation. Both pleomorphic, short, rod-shaped cells and coccoid cells were observed. Strains LS-286 (=ATCC BAA-452=BCRC 17198) and LS-293T(=ATCC BAA-406T=BCRC 17173T) represented a novel species of the genusRubrobacter, according to a phylogenetic analysis of the 16S rRNA gene, DNA–DNA hybridization, biochemical features and fatty acid composition. The nameRubrobacter taiwanensissp. nov. is proposed for this novel species, with LS-293Tas the type strain.Keywords
