Course Goal / Objective
The course handled and review the important metabolites in the expanded application of lactic acid bacteria from the perspective of bioengineering and biotechnology in terms of the food industry.
Course Content
Lactic acid bacteria (LAB) are a heterogeneous group of species, which synthesize lactic acid as the major product of sugar fermentation. LAB is an industrially important group of microorganisms used throughout the world for a large variety of food fermentations, such as those of dairy, wine, bread, seafood, and vegetables. In this course the adaptability of LAB to fermentation processes, their biosynthetic capacity, and metabolic versatility are some of the principal features that facilitate the application of LAB as microbial starters for producing, releasing, and/or increasing specific beneficial compounds in a fermented food will be explained. Moreover, the characterization and usage of new bacteriocins for food preservation and the detection, understanding, and control of the biogenic amine production by LAB will be handled.
