English abstract Air conidia production of Beauveria bassiana, strain CA-603 was studied based on modified diphasic system. The biomass yield obtained in the first phase based on submerged cultivation of fungus was processed using methodology providing different contact with air space. Our study indicated that productivity of the second stage of diphasic system is had inversely proportional dependence on depth of liquid fungal biomass. Increase of biomass depth is significantly decreased production of air conidia. Two methodology of biomass processing extending contact biomass with air space including distribution of fungal material on surface of hygroscopic paper and starch packaging peanuts were investigated. The novel substrates provided optimal contact between the submerged fungal biomass and the air, and overall, conidial production was directly proportional to the total area of air-to-fungal surface. Technologies based on the starch peanuts and hygroscopic paper were the most productive in comparison to the common technology where the submerged culture was transferred to flat containers. The advantages and disadvantages of these different production methods are discussed
