A total of 33 isolates of Fusarium moniliforme from several food or feed crops were grown on sterile cracked corn, and chloroform-isopropanol extracts were assayed for mutagenic activity in the Salmonella typhimurium-microsome system by using tester strain TA98 or TA100 or both. Extracts of 21 (64%) of the isolates assayed against TA100 were mutagenic. Activities of seven of these extracts were increased markedly with incorporation of the liver homogenate (S-9) into the assay. Seven (33%) of the isolates assayed against TA98 were weakly active, with the liver homogenate having little effect on reversion rates.
从几种粮食或饲料作物中总共分离出33株串珠镰刀菌,将其接种在无菌碎玉米上培养,然后用氯仿 - 异丙醇提取物,通过使用测试菌株TA98或TA100或两者,在鼠伤寒沙门氏菌 - 微粒体系统中测定其致突变活性。针对TA100检测的分离物提取物中,有21株(64%)具有致突变性。其中七种提取物的活性在测定中加入肝脏匀浆(S - 9)后显著增加。针对TA98检测的分离物中有七株(33%)活性较弱,肝脏匀浆对回复突变率影响很小。
