A Gram-stain-positive, aerobic, short rod-shaped bacterium, strain ZD1-4(T), 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 MB1-14(T). The major fatty acids of strain ZD1-4(T) were anteiso-C(15 : 0), C(16 : 0), C(18 : 0) and anteiso-C(17:0). 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 ZD1-4(T) was 63.8 ± 0.2 mol% (T(m)). 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 MB1-14(T). According to these genotypic and phenotypic data, it is evident that strain ZD1-4(T) represents a novel species of the genus Mycetocola, for which the name Mycetocola zhadangensis sp. nov. is proposed. The type strain is ZD1-4(T) ( =KACC 16570(T) =CGMCC 1.12042(T)).
