Definition

Noun: * Family Micrococcaceae: A taxonomic family of bacteria. These are typically spherical or elliptical, usually aerobic, eubacteria. A distinguishing characteristic is their production of yellow, orange, or red pigments. The family includes some toxin-producing forms, as well as harmless commensals (organisms living in/on another without harming it) and saprophytes (organisms living on decaying organic matter).

Usage Notes
  • This is a highly specialized, scientific term used in microbiology and taxonomy.
  • It is always treated as a singular noun when referring to the taxonomic group itself (e.g., "The family Micrococcaceae is...").
  • In formal scientific writing, the name is often italicized: .
Examples
  • Scientific Context:
    • Staphylococcus and Micrococcus are two well-known genera within the family Micrococcaceae.
    • The study focused on the pigment production capabilities of various members of the family Micrococcaceae.
    • According to the latest phylogenetic analysis, this bacterium belongs to the family Micrococcaceae.
Advanced Usage
  • Taxonomic Hierarchy: The term is used within the standard biological classification system (Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species). For example: Order → Family → Genus .
  • Clinical Context: In medical microbiology, identifying an organism as part of the family Micrococcaceae can be an initial step in diagnosing an infection, as it includes both pathogenic and non-pathogenic species.
Variants and Related Words
  • Micrococcaceae: The core family name, often used interchangeably with "the family Micrococcaceae."
  • Micrococcal (adj): Of or relating to the Micrococcaceae. (e.g., micrococcal nuclease).
  • Genus Micrococcus: The type genus of this family.
  • Genus Staphylococcus: A medically significant genus within this family.
Synonyms
  • Taxonomic Synonyms: There are no true common-language synonyms. In outdated taxonomic schemes, the classification may have differed, but in current standard taxonomy, "family Micrococcaceae" is the accepted term.
Related Phrases / Terms
  • Gram-positive cocci: A descriptive term based on staining and shape that includes many members of the family Micrococcaceae.
  • Coagulase-positive/negative: A key test used to differentiate pathogenic (a member of this family) from other, less harmful staphylococci and micrococci.
  • Commensal flora: Refers to the harmless or beneficial bacteria, including some from the family Micrococcaceae, that normally live on the skin or mucous membranes.
Noun
  1. spherical or elliptical usually aerobic eubacteria that produce yellow or orange or red pigment; includes toxin-producing forms as well as harmless commensals and saprophytes
