Kocuria rosea explained

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.[1] K. rosea has also been found to cause urinary tract infections in people with weakened immune systems.[2]

The normal habitat for this Kocuria species is skin, soil, and water.[3] It derives its name from the carotenoid pigment that it secretes.[4] Isolated colonies on a TSA plate are circular, 1.0–1.5 mm in size, slightly convex, smooth, and pink in color.[5]

Metabolism

K. rosea has been found to be able to biodegrade malachite green, azo dyes, triphenylmethane, as well as some other industrial dyes.[6] Due to its ability to biodegrade these dyes, it has become of interest as a potential means to biodegrade dyes that would otherwise take a long time to naturally break down. It also has been found to have the ability to perform keratin hydrolysis through the production of keratinases.[7]
