培养白僵菌一级菌种,过去主要用琼脂、白糖、蛋白胨作培养基,其成本高,来源也比较困难,还有没有别的物质代替呢?我们曾经用松毛虫、全麦麸、面条、锯末、红薯、南瓜、松针、松枝、刺槐叶、榆树叶、蝗虫做原料,均能培养出白僵菌,经过对比最好的原料是松毛虫。用松毛虫培养出来的白僵菌,烘干后每克菌粉含孢量达五百六十亿。用松毛虫做一级菌种培养原料有以下几点好处:
Beauveria bassiana cultivated a strain of bacteria, the past mainly with agar, sugar, peptone as a medium, the high cost, the source is more difficult, there are other substances instead? We have used pine caterpillars, whole wheat bran, noodles , Sawdust, sweet potatoes, pumpkin, pine needles, pine branches, acacia leaves, elm leaves, grasshoppers as raw materials, can cultivate Beauveria bassiana, after comparison the best raw material is the pine caterpillar. Beauveria bassiana cultivated with pine caterpillars, dried gram per gram of bacteria content of 56 billion. Dendrolimus to do a strain of raw materials have the following advantages:
