Definition

1. Noun:
   • A taxonomic family of bacteria: "Thiobacteriaceae" is the scientific name for a family of free-living bacteria. These bacteria are typically shaped like cocci (spheres) or rods.
   • Characterized by metabolic activity: The defining characteristic of this family is that its members obtain energy by oxidizing sulfur or various sulfur compounds.

Usage Examples

• Noun:
  • The genus Thiobacillus is classified within the family Thiobacteriaceae.
  • Researchers are studying the ecological role of the Thiobacteriaceae in sulfur cycles.

Advanced Usage

• In taxonomic hierarchy: The name is used in formal biological classification, following the binomial nomenclature system where "Thiobacteriaceae" denotes the family rank.
  • The order includes several families, most notably the Thiobacteriaceae.

Variants and Related Words

• Thiobacillus (n): A prominent genus within the family Thiobacteriaceae.
• Chemolithotroph (n): A broader nutritional category describing organisms, like those in Thiobacteriaceae, that derive energy from oxidizing inorganic compounds.

Synonyms

• Sulfur-oxidizing bacteria family: A descriptive synonym highlighting the key metabolic trait.
• Thiobacteria: An informal, shorter reference sometimes used for members of this family.

Related Terms

• Sulfur cycle: The biogeochemical cycle in which Thiobacteriaceae play a crucial role.
• Oxidation: The chemical process these bacteria use to generate energy.

Noun

1. free-living coccoid to rod-shaped bacteria that derive energy from oxidizing sulfur or sulfur compounds
