Method & Evidence

AimTo identify and characterize acetic acid bacteria strains with optimal fermentation characteristics for commercial Kombucha production.

MethodExperimental screening and characterization

ProcedureAcetic acid bacteria were isolated from various sources using a calcium carbonate-supplemented medium. Promising colonies were identified through biological, morphological, and genetic analyses. Selected strains were then evaluated for their fermentation performance under different temperature and time conditions, measuring parameters such as titratable acidity, acetic acid bacteria count, glucuronic acid, and gluconate content.
