Five cultures isolated from soil samples collected in Schirmacher oasis, Antarctica, have been identified as members of the family Micrococcaceae, with 3 belonging to the genus Micrococcus and two to Planococcus. The 3 Micrococcus isolates (37R, 45R and 49R) were red-pigmented and h a d ~ 75 mol% G + C in their DNA; they were identified as Micrococcus roseus. The two Planococcus isolates (30Y and Lz3OR) were yellow and orange in colour, and had 43·5 and 40·9 mol % G + C in their DNA respectively; they were identified as Planococcus sp.
