摘要
球形芽孢杆菌(Baci Llus Sphaericus)在蚊幼孳生地能自然繁殖,我们从盐城郊区的污水塘中分离获得BS—1012,通过对库蚊、伊蚊及按蚊的生物学测定而知,其毒性高于标准株BS—1593,通过血清学试验证明其血清型为H_(5a5b)。本文主要研究氮源,碳源,无机盐,pH,温度、培养方法对BS—1012生长发育及产毒能力的影响。寻找最适合其生长发育的培养基,便于生产及大面积推广应用。
A new strain of Bacillus Sphaericus has been isolated from a filthy puddle in the suburbs of Yan Cheng.Its seroval belongs to serogroup H_(5a5b).It is numbered BS—1012.The biological testshows that its toxicity to Cx pipienspallens,An sincnsis and An aegypli Surpasses BS—1593.This paper has studied the effects of carbon sources,nitrogen sources,complements of medium,temperature and pH on BS—1012 growth and toxicity production conditions.
