PRACTICAL WALKTHROUGH · PARAMETERS · COMMON MISTAKES
Bacterial fermentation converts sugars into acids, gases, or alcohols using specific microbes under controlled temperature and oxygen conditions.
Origin: Various ancient cultures (~8000 BCE to 4th‑century CE) — Mesopotamia, Korea, Middle East, China
See full technique reference →During fermentation, bacteria such as Lactobacillus, Acetobacter, and Propionibacterium metabolize carbohydrates via glycolysis and subsequent pathways, producing lactic acid, acetic acid, propionic acid, CO₂, and ethanol. The accumulation of these metabolites lowers pH, inhibits spoilage organisms, and generates characteristic flavors and textures.
