Noun: 1. A family of bacteria: Micrococcaceae is the scientific name for a family of typically spherical, Gram-positive bacteria. They are often aerobic (requiring oxygen) and are known for producing pigments in yellow, orange, or red colors. This family includes some forms that can produce toxins, as well as many harmless bacteria that live on the skin or in the environment as commensals or saprophytes.
