They are generally strict aerobes and can generally reduce nitrate. M. luteus oxidizes carbohydrates to CO2 and water, and it does not produce acid from glucose as well as it does not make arginine dihydrolase or b-galactosidase. Some Micrococcus are pigmented bacteria; for example, M. luteus produces yellow colonies and M. roseus produces redish colonies. Micrococcus species are oxidase-positive, which can be used to distinguish them from other bacteria like most Staphylococcus species, which are generally oxidase-negative.Micrococcus species can also be differentiated from staphylococcus species by the Taxo A Bacitracin disk test M. luteus has been isolated from human skin, animal and dairy products, and beer. It can be found in many other places in the environment, as well, like water, dust, and soil. M. luteus on human skin breaks down compounds in sweat into compounds with bad odor. M. luteus can grow well in environments with little water or high salt concentrations. M. varians is the second most frequently isolated species of micrococcus after Micrococcus luteus M. luteus has one of the smallest genomes of all bacteria. Hybridization studies show no close genetic relationship among the species of Micrococcus. For example, M. luteus and M. lylae are 40-50% genetically different. M. luteus has a G-C content of 65-75 mol%. M. varians has a G-C content of 66-72mol%. About half of the strains of M. luteus were found to carry plasmids 1 to 100MDa in size. So far two genome sequences have been done, one on Micrococcus sp. 28 plasmid pSD10 and another on Micrococcus luteus plasmid pMLU1. M. luteus имеет один из самых маленьких геномов среди всех бактерий. Гибридизационные исследования показывают отсутствие тесной генетической связи между видами Micrococcus. Например, M. luteus и M. lylae генетически различаются на 40-50%. У M. luteus содержание G-C составляет 65-75 моль%. У M. varians содержание G-C составляет 66-72 моль%. Было обнаружено, что около половины штаммов M. luteus несут плазмиды размером от 1 до 100 МДа. К настоящему времени было проведено два геномных анализа: один - плазмиды pSD10 Micrococcus sp. 28, другой - плазмиды pMLU1 Micrococcus luteus.
