![]() The data on the GC content of the DNA, chemical cell wall analysis, and a comparative analysis of the 16S rRNA sequences. There are around nine species that are recognized in the genus. The GC content of the DNA ranges from about 65 to 75 mol%. Most of the species produce carotenoid pigments. They are catalase-positive and usually aerobic with strictly respiratory metabolism. The genus Micrococcus consists of Gram-positive spheres occurring in tetrads and in irregular clusters that are usually non-motile and non-spore-forming. ![]() Micrococcus Luteus Gram Stain Characteristics This suggests that some of the Micrococcus species on the basis of ribosomal RNA analysis eventually can be re-classified into other microbial genera. Hybridization studies indicate that species within the genus Micrococcus are not closely related, showing as little as 50% sequence similarity. luteus have been found to overproduce the riboflavin virus when they are grown on toxic organic pollutants like pyridine. They also produce yellow or pink colonies when they are grown on the mannitol salt agar, micrococcus flavus, M. Some of the species of Micrococcus, such as M. Micrococci can often carry plasmids that provide the organism with useful traits. The genome of the Micrococcus is rich in guanine and cytosine, they typically exhibit about 65 to 75% GC-content. Micrococcus has a substantial cell wall in which it may comprise as much as 50% of the cell mass. They are indole negative, oxidase-positive, catalase-positive, and citrate negative. Micrococci have Gram-positive types of spherical cells that are ranging from about 0.5 to three micrometres in diameter and typically they appear in tetrads. Micrococcus species occur in a wide range of environments, including dust, water, and soil. Micrococcus is a genus of bacteria that is present in the Micrococcaceae family.
