Definition
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.
Usage Examples
- Noun:
- The laboratory identified the isolate as a member of the Micrococcaceae family.
- Some bacteria within the Micrococcaceae are common components of human skin flora.
- The study focused on the pigment-producing capabilities of various Micrococcaceae.*
Advanced Usage
- In taxonomic classification: The term is used precisely in microbiology and taxonomy to categorize a specific group of related bacterial genera.
- The genus Micrococcus is the type genus for the family Micrococcaceae.*
Variants and Related Words
- Micrococcus (n): A genus of bacteria within the family Micrococcaceae.
- Micrococcus luteus is a commonly studied species.
- Staphylococcus (n): A historically related but now distinct genus; some classification systems previously placed it within Micrococcaceae.
- Staphylococcus aureus is a significant human pathogen.
Synonyms
- Family Micrococcaceae: The full taxonomic designation.
- Micrococci (n, plural): A common, informal term for bacteria belonging to this family, though it can sometimes refer more narrowly to the genus .
Notes on Meaning
- Scientific vs. General Use: This word is almost exclusively used in scientific, medical, and microbiological contexts. It is not used in everyday conversation.
- Historical Context: The classification of bacterial families evolves. Some genera once included in Micrococcaceae (like ) are now placed in separate families based on genetic analysis.
