The article presents data on accumulation of biomass productivity Chlorella sp. K-1 and Ch. pyrenoidosa C-2 mono- and mixed microalgae cultures. It is established that at cultivation of mixed cultures of microalgae, an increase in the biomass concentration of biologically active substances (protein, carotenoids, chlorophyll a and b) compared to mono culturally.
In the experiment, we studied the possibility of adding dry biomass of microalgae consortium as a biologically active additives in culture media of microorganisms. The results revealed that when added to the culture medium of dry biomass consortium of microalgae at a concentration of 2,0 g/l, an increase in the cell growth of Escherichia coli and Enterobacter aerogenes by 32,6 and 36,4%, whereas in strains of Proteus mirabilis and Shigella flexneri growth of cells is of 43,0% and 47,0% compared to control. Studying an influence of microalgae consortium (at a concentration of 2 g/l) on growth of different strains of bifidobacteria B. bifidum strain 6 and strain 4 by 2 and 3 times, B. longum K-1 и K-3 by 3,5 and 4 times respectively compared to control.
