Inhibitory Effects of Beauveria bassiana Strain S1-7 on Lasiodiplodia theobromae under Different Fermentation Conditions
摘要
Abstract
Inhibitory effects of Beauveria bassiana strain S1-7 on pathogens Lasiodiplodia theobromae causing die back of Eucalyptus spp.were determined under different conditions by mycelium growth rate method.Re-sults showed that the inhibition rate was the highest when culture temperature was 28℃,the incubation time was 20 d,the pH value was from 7.0 to 8.0,and medium glucose,protein peptone and yeast powder content were 40 g/L,20 g/L and 20 g/L,respectively.In addition,the fermentation broth had little influence on in-hibitory effect when the high temperature was under 60℃for 4 hours,but inhibition rate decreased signifi-cantly when the temperature was higher than 60 ℃. The UV irradiation had little influence on the inhibition rate of the fermentation broth.关键词
