浙江省粮食中黄曲霉菌的产毒性能研究(Ⅰ) 黄曲霉产毒株比率及不同测定方法的比较

在我国的广西省孟昭赫等发现肝癌发生率与食品中的黄曲霉素含量高低有密切的关系,在国外的肯尼亚和泰国,其他学者调查发现肝癌发生率与随食品摄入的黄曲霉素含量呈线性相关。1978年,刘兴玠等调查了我国17个省的黄曲霉产毒株比率,发现浙江省的产毒株比率较低(7.4%)。测定10年后浙江省黄曲霉产毒性能的变化,对估计和监测及管理食品中黄曲霉毒素污染情况具有实际的指导意义。     

食物中毒汽水产毒霉菌的鉴定

In a soft drink caused food poisoning, white floccus was found and mould count was 6.0 x 10(2) CFU/ml. The Mycoflora was made of only one kind of mould which was identified as Penicillium janthinellum Biourge. This isolate can grow under anaerobic condition. The culture liquid of the isolate was fed to mice orally for toxicity test, which made the mice lose weight. An extract of the culture liquid was tested in weaned mice inaberitoneally for toxicity and all mice died in 24h. The toxic symptoms were tic, sway and paralysis of right rear-leg. Gross anatomy changes were gastrectosis, flatulence and intestinal edema. The conclusion is: the P. janthinellum isolate from the soft drink was the toxigenic mould.
