Characteristics of Bacillus subtilis metabolites contained in supernatants of its broth cultures are described. Metabolites contained bacterium-produced biologically active components ensuring cells growth and propagation. These components had bacteriostatic and bactericidal effect on gram-positive and gram-negative pathogenic and conditionally pathogenic microflora of gastrointestinal tract of human and animals. Enzymes produced by the bacterium (amylase, protease, cellulose-decomposing enzyme, lipase, pectinase) increased antagonistic properties of preparation and promote its probiotic effect.
