Micrococcus roseus

Micrococcus roseus is a gram positive bacterial cell that grows in the tetrad arrangement. The normal habitat for this Micrococcus species is skin, soil, and water. It derives its name from the carotenoid pigment that it secretes. Isolated colonies on a TSA plate are circular, 1.0–1.5 mm in size, slightly convex, smooth, and pink in color. Optimal growth temperatures range from 25 to 35 degrees Celsius. Micrococcus roseus is a strictly aerobic organism.
