Micrococcus is a genus of bacteria in the Micrococcaceae family. ... and M. roseus (red) produce yellow or pink colonies when grown on mannitol salt agar.
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.
Brachybacterium conglomeratum is a species of Gram positive, facultatively anaerobic, whitish yellow to pale brown pigmented bacterium.The cells are coccoid during the stationary phase, and irregular rods during the exponential phase. [1]
An MSA plate with Micrococcus sp. (1), Staphylococcus epidermidis (2) and S. aureus colonies (3). Mannitol salt agar or MSA is a commonly used selective and differential growth medium in microbiology. It encourages the growth of a group of certain bacteria while inhibiting the growth of others. [1]
The Timpe and Runyon classification of nontuberculous mycobacteria is based on the rate of growth, production of yellow pigment and whether this pigment was produced in the dark or only after exposure to light. [1] It was introduced by Ernest Runyon in 1959. [2] On these bases, the nontuberculous mycobacteria are divided into four groups:
Micrococcus spp. are obligate aerobes that inhabit human skin. Staphylococcus spp. also inhabit human skin, but they are facultative anaerobes. They ferment sugars, producing lactic acid as an end product. Many of these species produce carotenoid pigments, which color their colonies yellow or orange. Staphylococcus aureus is a major human ...
Micrococcus lylae was also first isolated during the same study) [2] In 1995, the species was reclassified into the genus Kocuria as Kocuria kristinae. [3] In 2018, further studies reclassified the species into genus Rothia as Rothia kristinae .
Kocuria rosea is a gram-positive bacteria that is catalase-positive and oxidase-positive.It has a coccus shape that occurs in the tetrad arrangement and is a strict aerobe that grows best from 25 to 37 °C. [2]
