A Gram-stain-positive, aerobic, short rod-shaped bacterium, strain ZD1-4T, was isolated from the Zhadang Glacier snow pit. The 16S rRNA gene sequence of the isolate showed highest similarity (98.8 %) to that of Mycetocola manganoxydans MB1-14T. The major fatty acids of strain ZD1-4T were anteiso-C15 : 0, C16 : 0, C18 : 0 and anteiso-C17 : 0. 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 ZD1-4T was 63.8±0.2 mol% (Tm). A number of phenotypic characteristics distinguished this bacterium from the type strains of other species of the genus Mycetocola. Moreover, the novel isolate showed only approximately 50 % DNA–DNA relatedness with M. manganoxydans MB1-14T. According to these genotypic and phenotypic data, it is evident that strain ZD1-4T represents a novel species of the genus Mycetocola, for which the name Mycetocola zhadangensis sp. nov. is proposed. The type strain is ZD1-4T ( = KACC 16570T = CGMCC 1.12042T).
