Abstract

A Gram-stain-positive, aerobic, short rod-shaped bacterium, strain ZD1-4, was isolated from the Zhadang Glacier snow pit. The 16S rRNA gene sequence of the isolate showed highest similarity (98.8 %) to that of MB1-14. The major fatty acids of strain ZD1-4 were anteiso-C, C, C and anteiso-C. It possessed diphosphatidylglycerol as one of the major polar lipids, and MK-10 and MK-11 as the predominant isoprenoid quinones. The DNA G+C content of strain ZD1-4 was 63.8±0.2 mol% ( ). A number of phenotypic characteristics distinguished this bacterium from the type strains of other species of the genus . Moreover, the novel isolate showed only approximately 50 % DNA–DNA relatedness with MB1-14. According to these genotypic and phenotypic data, it is evident that strain ZD1-4 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is ZD1-4 ( = KACC 16570 = CGMCC 1.12042).
