The searching of active catalase producers among the microscopic fungi

The screening among 158 fungal strains from different taxonomic groups - 128 new soil strains, from plant roots and 30 NCNM strains was carried out on the criterion of catalase synthesis. It was demonstrated that some new strains were more active than those from NCNM. All tested strains from the Penicillium and Aspergillus (108) genus had catalase activity and 26 representatives of other strains did not. Penicillium funiculosum strain, isolated from selected soils of Moldova, was selected as a potential catalase producer. This strain had a catalase activity of 244 units / ml. The optimal parameters for crop cultivation were: temperature of 28 gr.C, the cultivation period - 6 days, the pH value of the nutritional medium – 6.6.
