The Laboratory specializes in the making of molecular biological analyses in order to characterize the bacterial cultures used in dairy starter cultures. This allows for adding to the quality control of our company products monitoring of the type and strain of the microorganism cultures used. And since the technological and health qualities are most often individual for each starter culture, the production characteristics of the starter cultures and the functionality of the products are guaranteed in this way. The methods used allow evaluating the great variety of lactic acid bacteria isolated from the territory of Bulgaria and stored in our collection of microorganisms. The Laboratory has as its priority also to work on the early detection and fight against bacteriophage infections which threaten the production process of dairy products with the possibility to provide support to dairy processors in Bulgaria.
