[Growth peculiarities of probiotic strains of Bacillus subtilis at their joint cultivation in deep conditions].

Growth peculiarities of probiotic strains B. subtilis UKM 5139 and B. subtilis UKM 5140 have been studied at their joint cultivation in deep conditions. It has been shown that in such conditions of cultivation the growth of bacilli and the accumulation of biomass of the cells that possessed high antagonist properties have been intensified. The mixed culture grown when the medium was inoculated by the strains B. subtilis UKM 5139 and B. subtilis UKM 5140 with the ratio of 1:2 was distinguished by the highest specific growth rate. Applicability of synthetic and complex media both for separate and joint cultivation of bacilli has been shown.
