Description
Starter culture selection is the deliberate choice of microbial strains to initiate and control fermentation processes.
Technical
By selecting specific lactic acid bacteria, yeasts, or acetic acid bacteria, the fermentation pathway is directed toward desired acids, alcohols, and flavor compounds. Temperature, pH, and substrate composition steer microbial growth kinetics and metabolic fluxes, enabling precise control over acidification, flavor development, and safety.
Science
Primary Reaction
Fermentation of carbohydrates to lactic acid, ethanol, CO2, and other metabolites.
