苏芸金杆菌经过七十年的研究才引起人们的重视;在农业上现在成为世界公认的安全的细菌杀虫剂之一。各国科学家继续挖掘它的潜力,寻找它的新用途。在我国,苏芸金杆菌也是研究和应用比较广泛的微生物杀虫剂之一。本文着重阐述近年来的进展情况和过去评述中未提及的部分。一、苏芸金杆菌分类学的研究 1.分类地位问题的争议 Berliner 1911年报道苏芸金杆菌时,它的分类地位是明确的,它属于Bacillus属中的一个种,种名为Bacillus thuringiensis Berliner。可是由于当时分类鉴定的主要依据是形态学和生理生化特征,而在Bacillus属中的杆菌,无论其形态学特征或生理生化特 Bacillus thuringiensis has attracted people’s attention after seventy years of research and is now one of the most recognized and safe bactericide in agriculture in the world. National scientists continue to tap its potential to find new uses. In our country, Bacillus thuringiensis is also one of the most widely used microbial insecticides. This article focuses on recent developments and parts that were not mentioned in past commentary. First, Bacillus thuringiensis taxonomy 1. Disagreement status issues Berliner Bacillus thuringiensis Berliner reported in 1911, its taxonomic status is clear, it belongs to a species of Bacillus genus, named Bacillus thuringiensis Berliner . However, because the main basis for the identification of the time was morphological and physiological and biochemical characteristics, and in Bacillus genera, regardless of their morphological characteristics or physiological and biochemical
