不同碳、氮营养对球孢白僵菌生物学特性和抑菌活性的影响
Effects of Carbon Sources and Nitrogen Sources on the Biological Characteristics and Antifungal Activity of Beauveria bassiana
摘要
Abstract
The biological characteristics of Beauveria bassiana were compared in the effects of different carbon sources and nitrogen sources on the mycelium growth, mycelium biomass and conidia production.The results showed that Beauveria bassiana could use many carbohydrates and nitrogen sources for the mycelia growth, but the most suitable carbon source and nitrogen source was white granulated sugar and peptone, respectively.The effects of carbon and nitrogen sources on the conidial production of Beauveria bassiana were significant.The conidial production cultured with white granulated sugar and potassium nitrate was the largest, but mannitol and ammonium sulfate was the smallest.Mycelium biomass cultured with white granulated sugar and peptone was the best, glycerol and urea was the poorest.By means of mycelium growth rate, the inhibitory rates of metabolic liquid cultured with different carbon sources and nitrogen sources were tested.The inhibitory rates showed that the metabolic liquid eulturcd with different carbon sourees and nitrogen sources had significant difference on the 5 tested Fusarium SPP.Among the metabolic liquid, the inhibitory rates of glycerol and ammonium sulfate were the best; lactose and urea were the lowest.关键词
