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.
M. luteus on human skin transforms compounds in sweat into compounds with an unpleasant odor. Micrococci can grow well in environments with little water or high salt concentrations, including sportswear made with synthetic fabrics. [4] Most are mesophiles; some, like Micrococcus antarcticus (found in Antarctica) are psychrophiles.
Human microbiota are microorganisms (bacteria, viruses, fungi and archaea) found in a specific environment. They can be found in the stomach, intestines, skin, genitals and other parts of the body. [1] Various body parts have diverse microorganisms. Some microbes are specific to certain body parts and others are associated with many microbiomes.
The family Micrococcaceae includes bacterial genera of Gram positive cocci that inhabit the air and skin, such as Micrococcus luteus. ... Micrococcus Cohn 1872 ...
Micrococcus luteus: bacterium: cheese [2] Micrococcus lylae: bacterium: meat sausage [2] [5] Mucor hiemalis: fungus: soy bean curd [2] Mucor plumbeus: fungus: cheese ...
The survival of some microorganisms exposed to outer space has been studied using both simulated facilities and low Earth orbit exposures. Bacteria were some of the first organisms investigated, when in 1960 a Russian satellite carried Escherichia coli, Staphylococcus, and Enterobacter aerogenes into orbit. [1]
Colonies of Micrococcus luteus on Tryptic Soy Agar. Cultivation 48 hours, 37°C. Trypticase soy agar or Tryptic soy agar (TSA) is a growth media for the culturing of moderately to non fastidious bacteria. It is a general-purpose, non-selective media providing enough nutrients to allow for a wide variety of microorganisms to grow.
Sarcina is a genus of gram-positive cocci bacteria in the family Clostridiaceae. [2] [3] [4] A synthesizer of microbial cellulose, [5] various members of the genus are human flora and may be found in the skin [6] and large intestine. [7]
