Rye is a nutritionally and healthy valuable cereal. It is a significant substrate for biotechnological processing. This review presents the basic procedures for rye sourdough refreshing, the characteristics of used LAB and yeast, the types of sourdough use in the Czech Republic and in global perspective. The fermentation process leads to the activation and accessibility of a number of healthy bioactive components of rye flour. Compounds with antifungal activity formed during fermentation can effectively enhance the microbial stability of bread.
