在高温季节生产白僵菌,尤其是在南方地区,在开放性扩大发酵的时候,常因杂菌的大量污染而招致失败。不少生产白僵菌的单位都反映,认为在高温季节杂菌污染现象严重,难以生产。因此,如何克服在高温季节生产白僵菌时出现的杂菌污染,是一个重要的问题。据观察,在高温季节所出现的杂菌以霉菌类为主。在气温超过30℃,空气相对湿
Beauveria bassiana is produced during the hot season, especially in the South, where it often fails due to extensive contamination of bacteria. Beauveria bassiana production of many units are reflected that in the hot season, serious bacterial contamination, difficult to produce. Therefore, how to overcome the bacterial contamination in the production of Beauveria in the hot season is an important issue. It is observed that in the hot season there are mold-based bacteria. At temperatures above 30 ° C, the air is relatively wet
