Subject is focused on functional properties, metabolism and genetics of lactic acid bacteria (LAB), progress and trends in dairy starter cultures, new applications of LAB in food production, cosmetics and preventive medicine and on the methods of selective enumeration of LAB in mixtures.
Aim of the course -
Last update: Pátková Vlasta (15.11.2018)

Students will be able to use:

• new information concerning functional properties of LAB, their metabolites and their defense mechanisms against bacteriophages,

• possible food and non-food applications of LAB,

• control methods of LAB stability in products.

• Characteristics of particular species of LAB, actual taxonomy and safety.

• Metabolism of LAB and its regulation (saccharides, EPS, proteolysis and amino acid catabolism, citrates, antimicrobially and antivirally active metabolites).

• Bacteriphages of LAB, defense mechanisms of LAB.

• Genetics of LAB, properties of chosen genetically modified LAB strains.

• Functional properties of LAB - probiotics, prebiotics, synbiotics.

• New applications of LAB in food processing (production of biologically active compounds-vitamines, bioactive peptides).

• LAB applications for gut microbiota modulation (gut immune system modulation), cholesterol transformations, preventive treatment of urovaginal and respiratory infections.

• Plate count and molecular-biologic methods of LAB estimation in mixtures.
