The starter cultures at LB Bulgaricum are marketed under the brand name LBB. These cultures are among the most important ingredients in the production of Bulgarian dairy products, which is why specialists at LB Bulgaricum give them special attention. In the company's Research Centre, a unique collection of over 1,000 species of lactic acid and bifidobacteria is stored, enriched, and studied. Some of these species are included in more than 100 different starter combinations.
