Sep 28, 2023 · Here are the key aspects of the morphology of M. luteus: Fig. Micrococcus luteus colony morphology on Nutrient agar. Cell Shape: It is a spherical bacterium, which means it has a coccoid or cocci shape. Cocci are round or oval cells, and M. luteus cells typically appear as small, spherical entities.
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. The bacterium also colonizes the human mouth, mucosae, oropharynx and upper respiratory tract.
Sep 1, 2007 · Streak plate isolation of a mixed broth culture showing colonial morphology of Escherichia coli (white colonies) and Micrococcus luteus (yellow colonies). The culture was grown on trypticase soy agar (TSA) and incubated for 72 hours at 37oC.
