Objectives of the Course

The aim of this course is to allow graduate students to learn about lactic acid bacteria in the dairy industry.

Course Content

Morphological, physiological, biochemical and immunological characteristics, phylogenic origins, taxonomies and classifications, genetic structures and industrially important lactic acid bacteria of the genus Lactobacillus, Streptococcus, Enterococcus, Lactococcus, Pediococcus, Leuconostoc, Bifidobacterium, Carnobacterium, Propionibacterium, which constitute the basis of biotechnology in the industrial processing of milk. genes and gene systems, metabolism and factors affecting metabolic rate, technological functions, bacteriophage mechanism, transport of carbohydrates, amino acids and peptides, minerals, cations and anions in lactic acid bacteria, flow of lactic acid and other end products, probiotic lactic acid used in milk technology. It includes topics such as bacteria and their benefits for human nutrition and their effects on human health, genetically modified lactic acid bacteria and their potential use in milk technology, the importance and necessity of knowing the safety issues regarding lactic acid bacteria used in milk technology.
