浅灰链霉菌230(Streptomyces griseolus230)是从土壤中分离出有杀钉螺作用的放线菌,属浅灰链霉菌的的一个新株。1982年从菌粉中分离获得杀螺有效组分230—2,杀螺单体230—2B,该化合物为浅黄色结晶,初步认为是吲哚骈咔唑母核结构的生物碱。对230—2及230—2B的杀螺、杀螺卵和对几种动、植物的毒性作了初步观察。 Streptomyces griseolus 230 is an actinomycete isolated from soil that acts as a snail-killing agent and a new strain of Streptomyces. In 1982, the active component of Spirulina maxima 230-2 and 230-2B were isolated from the bacterial strain. The compound was a light yellow crystal and was initially considered as the alkaloid of the indole carbazole core structure. On the 230-2 and 230-2B kill snail, kill spiro eggs and several animal and plant toxicity made a preliminary observation.
