Abstract
A method for preparing of microbial starter cultures of lactic acid bacteria, fermented at aeration under conditions of high optical density, at that method comprises stages of cultivation of lactic acid bacteria in cultural medium, containing at least one yield enhancing agent, selected from the group consisting of a purine base, pyrimidine base, nucleoside, nucleotide, and theirs derivatives in concentration, providing for content in cultural medium of at least one 1 μM of the mentioned at least one yield enhancing agent, at finishing of fermentation; and at least one porphyrinic compound, and collection of lactic acid bacteria for production of culture of lactic acid bacteria, where the yield enhancing agent leads to increased yield of collected lactic acid bacteria in comparison with cultivation of microorganism at identical conditions and in similar medium, containing less than 1 μM of each yield enhancing agent, at finishing of fermentation.
