Micrococcus
''Micrococcus'', from Ancient Greek μικρός (''mikrós''), meaning "small", and κόκκος (''kókkos''), meaning "sphere", is a genus of bacteria in the Micrococcaceae family (biology), family. ''Micrococcus'' occurs in a wide range of environments, including water, dust, and soil. Micrococci have Gram-positive spherical cells ranging from about 0.5 to 3 micrometers in diameter and typically appear in tetrads. They are catalase positive, oxidase positive, indole negative and citrate test, citrate negative. ''Micrococcus'' has a substantial cell wall, which may comprise as much as 50% of the cell mass. The genome of ''Micrococcus'' is rich in guanine and cytosine (GC), typically exhibiting 65 to 75% GC-content. Micrococci often carry plasmids (ranging from 1 to 100 MDa in size) that provide the organism with useful traits. Some species of ''Micrococcus'', such as ''M. luteus'' (yellow) and ''M. roseus'' (red) produce yellow or pink colonies when grown on mannitol salt agar ...

Micrococcus Luteus
''Micrococcus luteus'' is a Gram-positive to Gram-variable, nonmotile, tetrad-arranging, pigmented, saprotrophic coccus bacterium in the family Micrococcaceae. 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. ''Micrococcus luteus'' is generally harmless but can become an opportunistic pathogen in immunocompromised people or those with indwelling catheters. It resists antibiotic treatment by slowing of major metabolic processes and induction of unique genes. Its genome has a high G + C content. ''Micrococcus luteus'' is coagulase negative, bacitracin susceptible, and forms bright yellow colonies on nutrient agar (hence its scientific species name ''luteus'' which means "yellow" in Latin). ''Micrococcus luteus'' has been shown to survive in oligotrophic environment ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Micrococcus Lylae
''Micrococcus lylae'' is a gram positive bacterium. The normal habitat for this ''Micrococcus'' species is skin, dust, and water. Its type strain is ATCC 27566. It grows in tetrads, irregular clusters, and cubical packets of eight, and colonies are often brightly pigmented. They are strictly aerobic Aerobic means "requiring air," in which "air" usually means oxygen. Aerobic may also refer to * Aerobic exercise, prolonged exercise of moderate intensity * Aerobics, a form of aerobic exercise * Aerobic respiration, the aerobic process of cellu ....

Micrococcaceae
''Micrococcaceae'', from Ancient Greek μικρός (''mikrós''), meaning "small", and κόκκος (''kókkos''), meaning "sphere", includes bacterial genera of Gram positive cocci that inhabit the air and skin, such as '' Micrococcus luteus''.

Riboflavin
Riboflavin, also known as vitamin B2, is a vitamin found in food and sold as a dietary supplement. It is essential to the formation of two major coenzymes, flavin mononucleotide and flavin adenine dinucleotide. These coenzymes are involved in energy metabolism, cellular respiration, and antibody production, as well as normal growth and development. The coenzymes are also required for the metabolism of Niacin (nutrient), niacin, vitamin B6, vitamin B6, and folate. Riboflavin is prescription drug, prescribed to treat Corneal ectatic disorders, corneal thinning, and taken orally, may reduce the incidence of migraine headaches in adults. Riboflavin deficiency is rare and is usually accompanied by deficiencies of other vitamins and nutrients. It may be prevented or treated by oral supplements or by injections. As a water-soluble vitamin, any riboflavin consumed in excess of nutritional requirements is not stored; it is either not absorbed or is absorbed and quickly clearance (pharma ...
