Fourteen strains of Pleurotus ostreatus (Jacq.: Fr.) Kumm. (Agaricales s.l.) were investigated as possible producers of biologically active substances. After submerged cultivation, biologically active materials were isolated as extracts from cultural liquids and mycelia. Extracts were evaporated and dry residue dissolved. Antimicrobial activity was tested by the method of diffusion in agar medium inoculated with microorganisms. Disks saturated with solution were used. All strains manifest antimicrobial activity during submerged cultivation in experiments with extracts; cultural liquids demonstrated only minimal activity, so these strains have low levels of biosynthesis. Extracts of fruit bodies grown on corn were inactive. For the next investigation, one strain of P. ostreatus with the highest levels of biosynthesis was chosen. During submerged cultivation this strain produced two different substances with antibiotic activity, one with high activity against Aspergillus niger INA 00760 and the other with activity against Gram-positive as well as Gram-negative bacteria. Antifungal activity against Aspergillus niger/i> INA 00760, Saccharomyces cerevisiae RIA 259, and Candida albicans INA 00763 in mycelium extracts was not found. Mycelial extract was fractionated and it was shown that antimicrobial substance (or substances) in mycelial extract makes up not more than 1% of dry weight. Investigation of mycelial extract as anticancer and antitoxic drugs was studied in CBA mice. Anticancer action was tested in mice transplanted with Ehrlich’s ascites tumor. Toxic effect (decreasing of body weight and leucopenia) was noted in animals after cyclophosphamide (CP) administration in doses of 100 mg/kg. Extract was administrated daily. The first extract injection was given 2 h after CP administration. A number of leucocytes in peripheral blood were studied after CP treatment, producing a decrease of leucopenia level during this period. According to our data, P. ostreatus extracts produce a decrease of CP hematotoxicity.
