Abstract

Medicinal probiotic Sporobacterin is based on the Bacillus subtilis 534 strain, which has been shown to have antimicrobial activity against many bacteria, both the collection strains and the antibiotic-resistant forms of clinical isolates of pathogenic bacteria and fungi. Considering this strain as an antibiotic producer, a step-by-step mutagenic treatment was carried out in order to obtain a variant that consistently exhibits a certain high-level antibiotic activity. A mutant variant was obtained during the three stages of mutagenic treatment and selection; it effectively suppresses the growth of pathogenic staphylococci, including methicillin-resistant staphylococcus (MRSA).
