The lactic acid bacteria: a literature survey

Area of Science:

• Microbiology
• Food Science
• Fermentation Technology

Background:

• Lactic acid bacteria (LAB) are crucial in food fermentation, notably in dairy and alcoholic beverages.
• They offer significant contributions to human health, including potential probiotic effects.

Purpose of the Study:

• To provide a comprehensive overview of lactic acid bacteria (LAB).
• To elucidate the diverse functions of LAB as starter cultures and their health benefits.
• To simplify the acquisition of information on various LAB species and their characteristics.

Main Methods:

• Literature review synthesizing existing research on lactic acid bacteria (LAB).
• Detailed examination of LAB species including Lactobacillus, Lactococcus, Leuconostoc, Pediococcus, Carnobacterium, and Enterococcus.
• Analysis of LAB habitats, food associations, physiological and biochemical characteristics, and taxonomy.

Main Results:

• Information presented covers species identification, habitat, food sources, and culture media.
• Key trends discussed include the use of nisin for food preservation and the role of probiotics in modulating gut health.
• The review details classic descriptions and taxonomic classifications of various LAB.

Conclusions:

• Lactic acid bacteria (LAB) are versatile microorganisms with significant industrial and health implications.
• Understanding LAB characteristics is vital for optimizing fermentation processes and exploring probiotic applications.
• Further research into probiotic strains holds promise for preventing pathogen-induced intestinal issues.
