Binomial name
Micrococcus roseus

Micrococcus roseus is a gram positive bacterial cell that grows in the tetrad arrangement.[1] The normal habitat for this Micrococcus species is skin, soil, and water.[2] It derives its name from the carotenoid pigment that it secretes.[3] 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.[4]
