Halorubrum xinjiangense sp. nov., a novel halophile isolated from saline lakes in China

Int J Syst Evol Microbiol. 2004 Sep;54(Pt 5):1789-1791. doi: 10.1099/ijs.0.63209-0.

Abstract

A novel halophilic archaeon, strain BD-1T, was isolated from Xiao-Er-Kule Lake in Xinjiang, China. The taxonomy of strain BD-1T was studied by polyphasic methods. According to 16S rRNA gene sequence similarity, strain BD-1T was phylogenetically related to Halorubrum trapanicum (98.4 %), Halorubrum sodomense (98.0 %), Halorubrum distributum (97.8 %) and Halorubrum coriense (97.3 %). Strain BD-1T is able to grow at 10 degrees C and further differs physiologically from the above species in the assimilation of sugars. The G + C content of DNA is 68.0 % (Tm). The DNA-DNA relatedness values to Hrr. trapanicum and Hrr. distributum are 47 and 24 %, respectively. It is concluded that strain BD-1T represents a novel species of the genus Halorubrum, for which the name Halorubrum xinjiangense sp. nov. is proposed. The type strain is BD-1T (= AS 1.3527T = JCM 12388T).
