Micrococcus luteus

Structure and Physiology

This bacteria is Gram-positive, spherical, and an obligate aerobe. M. luteus is part of the normal flora of the human skin.

Transmission and Disease

M. luteus is rarely found to be responsible for infections. Only those with compromised immune systems are thought to be susceptible to an infection.


M. luteus is capable of surviving in environments of low nuturients and can tolertate drying and high salt environments, and because of this and its ability to form biofilms, it is relevant when considering disinfection of food contact surfaces.
