摘要:

采用砂土管和滤纸片两种保藏方法,对分属31个亚种的61株有代表性的苏云金芽孢杆菌(Bacillus thuringiensis)经过1—23年保存后的菌体存活情况、形态特征及对林业主要害虫舞毒蛾(lymantria dispar)幼虫的杀虫活性进行了试验;并对苏云金芽孢杆菌5个亚种的标准菌株和保存不同年限后的11项生理生化特性及酯酶型进行了测定。

Abstract:

61 strains of Bacillus thuringiensis belonging to 31 subspecies, preserved by two methods of sterie sand and filter paper for 1 - 23 years were tested. Their survival, morphological characteristics, toxicity against insects (Lymantria dispar) were measured. Physiological and biochemical characteristics and estarases of 5 subspecies of Bacillus thuringiensis preserved from 1979 to 1992 were determined.

Key words: Bacillus thuringiensis, Conservation, Bioassay
