Course Goal / Objective
This course is to provide a brief overview of the potential of lactic acid bacteria as biological catalysts for the production of different organic compounds for food and non-food sectors based on their diversity, metabolic- and stress tolerance features, as well as the use of genetic/metabolic engineering tools for enhancing their capabilities.
Course Content
This course has summarized the classification of LAB strains, and their metabolic pathways for the biosynthesis of lactic acid, ethanol, and acetic acid. It has also demonstrated its application in various food industries for making fermented milk (yogurt), cheese, beverages, bread, and animal foods. Besides, the wide spectrum of LAB-based probiotics, bacteriocins, exopolysaccharides, biopreservatives, and their relevant benefits to human health will also be discussed.
