Definition

Noun: * A family of bacteria, specifically the family Lactobacillaceae, characterized as Gram-positive, non-spore-forming, and typically rod-shaped or spherical. They are primarily known for fermenting carbohydrates, especially sugars, to produce lactic acid as a major metabolic end product. This group includes many species important in food production (e.g., yogurt, cheese, sauerkraut) as well as some that are part of the normal human microbiota or can act as opportunistic pathogens.

Usage
  • The term is used in scientific and microbiological contexts to classify and discuss this specific taxonomic family of bacteria.
  • It is often used when describing the microbial composition of fermented foods, probiotics, or certain infections.
Examples
  • Scientific Classification: "The genus , commonly used in yogurt starters, belongs to the family ."
  • Food Science: "The fermentation process in sauerkraut is driven primarily by members of the ."
  • Microbiology: "Researchers studied the gut microbiome, noting a high prevalence of in healthy subjects."
Advanced Usage
  • The family name is often used interchangeably with in many texts, though taxonomic revisions may specify differences. In current precise taxonomy, is the more formally accepted name for this group.
Variants and Related Words
  • Lactobacillaceae (n): The modern, more formally accepted taxonomic name for this family of bacteria.
  • Lactic acid bacteria (n, plural): A common descriptive term for bacteria, including those in this family, that produce lactic acid as a primary fermentation product. This is a functional grouping, not a strict taxonomic one.
  • Lactobacillus (n): A historically significant genus within this family, though recent taxonomic changes have reclassified many species into new genera.
Synonyms
  • Lactic acid bacteria (in a broad, functional sense)
  • Lactobacillaceae (the modern taxonomic synonym)
Notes on Different Meanings
  • The term Lactobacteriaceae has a single, specific meaning in microbiology: it refers to the taxonomic family. It does not have general or idiomatic meanings outside this scientific context.
