夏、秋两季的高温,是造成菌株变异退化的主要原因。在电力不足和没有冰箱的情况下,为了使菌株的繁育保纯与扩大培养协调起来,我们因地制宜地采用了几种降温的土办法,能在短期内较好的保藏“白僵菌208”菌种。 1.冷泉水保藏 将斜面菌种试管用牛皮纸包好,外面再包塑料纸,然后插入冷泉口或流动冷泉沟内,试管上部三分之一露出水面,可保藏一个月左右。 2.井水保藏 将斜面菌种试管用蜡封口,装入塑料袋或瓶子内,外捆重物沉入井底,可保藏半个月左
The high temperature in summer and autumn is the main reason for the variation and degeneration of the strains. In the case of lack of electricity and no refrigerator, in order to reconcile the breeding and expansion of the strains, we have adopted several methods of cooling soil in order to better preserve the “Beauveria bassiana 208” bacteria in a short period of time Species. 1. Cold Spring Water Storage Bevel bacteria test tube wrapped with kraft paper, and then outside the plastic wrap, and then insert the cold spring mouth or mobile cold spring ditch, the upper third of the test tube to reveal the water, can be stored for about a month. 2. Well water preservation Bevel bacteria tube sealed with wax, into plastic bags or bottles, the outer bundle of heavy objects sink into the bottom, can be preserved for half a month left
