Micrococcus antarcticus (lat.) Is a type of gram-positive cold - adapted aerobic spherical bacteria with a fairly low basic temperature of growth. They were found at the Chinese Great Wall Antarctic Station . Colonies are yellow, slimy and fluffy. The optimum growth temperature is +15 ... + 17 ° С. Comparison of 16S rRNA sequences indicated that it is a member of the genus Micrococcus . The phenotypic certainty of the species with respect to Micrococcus luteus and Micrococcus lylae strains was confirmed by 40% DNA similarity. It is precisely determined that the main diaminic acid of the peptidoglycan of the cell wall is lysine . The content of HZ in DNA is 66.4% typical for Micrococcus .
