What does Micrococcus luteus do?
What does Micrococcus luteus do?
Micrococcus luteus degrades the compounds in sweat into ones producing unpleasant odors. It also has the ability to degrade pollutants such as petrol. Pathogenicity: Although generally a harmless saprophyte, Micrococcus luteus can act as an opportunistic pathogen.
Is Micrococcus luteus harmful to humans?
In the case of Micrococcus luteus strain ATCC 4698, the organism is not hazardous to human health or the environment; and exposure to Canadians and the environment and Canadians is low. Therefore, it is concluded that Micrococcus luteus strain ATCC 4698 is not harmful to human health or to the environment.
What diseases are caused by Micrococcus luteus?
luteus. Micrococci have occasionally been reported as the cause of pneumonia, meningitis associated with ventricular shunts, septic arthritis, bacteremia, peritonitis, endophthalmitis, CR-BSI and endocarditis.
How do you get Micrococcus luteus?
luteus is considered an opportunistic pathogen that can be responsible for nosocomial infections. M. luteus can cause skin infections and is sometimes clinically mistaken for Staphylococcus aureus. This bacterium can be transmitted due to poor hand-washing practices.
Is Micrococcus luteus a Halophile?
This is in agreement with the reports of Ventosa et al., (1988) on the Biology of moderately halophilic bacteria [20]. The results from this research revealed that Micrococcus luteus, Staphylococcus aureus, and Staphylococcus lentus are halotolerant organisms.
What is the size of Micrococcus luteus?
KEY MICROSCOPIC APPEARANCE

Is Micrococcus luteus a lactose fermenter?
As the microbe is gram positive this means that it has a large peptidoglycan layer and lacks a lipopolysaccharide layer. The MacConkey agar is selective for gram-negative which is why my microbe didn’t show much growth on it, and because it didn’t change colors it means it didn’t ferment the lactose.
What size is Micrococcus luteus?
about 0.5-3.5 micrometer
A gram-positive aerobic harmless bacterium involved in the conversion of nitrate to nitrite. Micrococcus luteus has a size of about 0.5-3.5 micrometer in diameter arranged usually in irregular clusters and generally reduced nitrate.
What does Micrococcus mean?
Micrococcus(noun) a genus of Spherobacteria, in the form of very small globular or oval cells, forming, by transverse division, filaments, or chains of cells, or in some cases single organisms shaped like dumb-bells (Diplococcus), all without the power of motion. See Illust. of Ascoccus.
Does Micrococcus produce a yellow pigment?
a yellow pigment produced by a novel bacterium , Micrococcus luteus strain BAA2. The growth conditions of M. luteus strain BAA2 were optimized. It showed the optimum growth (OD: 0.55 at λ 660) at 28ºC (pH 7, 24 h), while the maximum pigment (OD: 0.50 at λ 466) production was at 36 h (pH 7). The yellow pigment
What is Micrococcus species?
Micrococcus Species. Micrococcus is defined as a Gram-positive aerobic bacterium that is 0.5 to 3.5 micrometers in diameter. Micrococcus cells can be observed under the microscope as spherical cells forming pairs or clusters. It belongs to the member of the Micrococcaceae family.
