Micrococcus luteus is a Gram-positive to Gram-variable, nonmotile, tetrad-arranging, pigmented, saprotrophic coccus bacterium in the family Micrococcaceae. [1] It is urease and catalase positive. An obligate aerobe , M. luteus is found in soil, dust, water and air, and as part of the normal microbiota of the mammalian skin.
