Micrococcus

 

a genus of spherical (diameter, 1–2 μ), nonmotile, nonsporiferous, gram-positive bacteria that reproduce by division in two or three planes and are found singly or in irregular masses.

On solid nutrient media, micrococci form smooth, round colonies of white, yellow, or red. Certain species (for example, M. pyogenes) cause purulent diseases. Micrococci inhabit soil, fresh and salt waters, and food products. Some species develop in brines and cause the appearance of red spots on pickled fish.
