摘要

用各种方法从球形芽孢杆菌1593株孢子中分离出斯氏按蚊幼虫的致死部分，冷冻和解冻的效果最好，提取物主要由蛋白质组成，分子量高，24小时内死亡率100%。由于其易于提取且缺乏二氨基亚戊酸，有毒部分被认为位于孢子外壳外。

[Isolation of a spore fraction of Bacillus sphaericus toxic for larvae of Anopheles].

A lethal fraction for Anopheles stephensi larvae has been isolated from Bacillus sphaericus strain 1593 spores by various methods The best results have been obtained by freezing and thawing which give an extract made in majority of protein with high molecular weight and causing 100% of mortality in 24 hours. Because of its easy extracction and its lack of diaminopimelic acid, the toxic fraction is thought to be located outside the spore coats.
