Beauveria bassiana Konidilerinin Katı Faz Fermantasyonu ile Kitlesel Üretimi için Bazı Tahılların İncelenmesi

This study was conducted to test five substrates (whole rice, broken dovme, wheat and burghul) for the mass production of Beauveria bassiana isolate 5-4, known be affective against stored-cereal pests. A solid-state fermentation technique used, amount product, number conidia, germination, hydrophobicity thermotolerance their virulence on Rhyzopertha dominica adults were used evaluate success substrates. For production, 100 g a substrate in polypropylene bag. After sterilization inoculation, bags sealed incubated 14 days at 25ºC. Hydrophobicity assessed using aqueous-solvent partitioning method with PM buffer, liquid paraffin as two phases. Thermotolerance tests by exposing conidia 35, 40 45°C 15, 30 60 minutes. In test, released into gr mixed kept 25oC 65% relative humidity darkness days. The highest product obtained whole rice (4.10g/bag), followed wheat, dövme burghul. achieved (10.24x1010conidia/g) (9.62x1010conidia/g). germination rates did not vary significantly. Significantly higher rate (88.73%). from burghul showed than those other caused 80.3% 72.0% mortalities, respectively, significantly others. Rice found better choice this ultimate purpose is suppress pest populations, awareness its shortcomings. It crucial all important characteristics produced together assessment
