Abstract: In order to improve the existing method of Beauveria bassiana Prodution, We made many-sided and explorative experimental researches on the relevant technical problems in the technology of brick type semi-solid fermentation culture method to mechanizedly produce Beauveria bassiana spore powder and deep-level liquid fermentation by means of carrier and achieved some success. The experimental results suggested:FL-85055 and FL-86004 were ideal prescriptions of liquid culture medium and the average spore output was 9.16 hundred million/ml and 8.15 hundred million/ml respectively,which was 1.85 times more than the production by the indigenous method with common 5% wheat skin soak; screened out Number C prescription of semi-solid fermentation culture medium and the average spore output attained 890.7 hundred million/g,which was 7.91 times more than the fungicide by the regular indigenous method with spore output 100 hundred million/g; selected out the ideal carrier FLT-8504 cultured by the semi-solid fermentation; the ratio of optimization combination of the culture medium, carrier and inoculation quantity was 1:3:6.
