The ability of joint cultivation of Bacillus subtilis UCM B-5007 and Escherichia coli M-17 in subsurface conditions has been studied. These strains are available for creation of a new complex probiotic. Symbiotic relationships between these microorganisms were proved. Bacillus subtilis and Escherichia coli strains use different growth "strategy". The most optimum ratio of cultures (1:1) for growth, biomass accumulation, and for antagonism to test-cultures has been chosen.
