从食品检样及食品工厂外环境采样中分离到十二株黄曲霉菌,并用大米粉产毒培养基对其进行了产毒培养及黄曲霉毒素B_1含量的测定,结果两株产生黄曲霉毒素B_1,其产毒量较低,用固定后中段再展薄层法测定的两株均含10μg/kg,产毒株比例为16.67％,对预防人畜的食物中毒和潜在慢性作用提供了一些数据和参考。现将实验结果总结如下。 十二株黄曲霉菌用大米粉培养基进行产毒培养,并用固定后中段再展薄层法对其产生黄 Twelve strains of Aspergillus flavus were isolated from the food sample and the sampling outside the food factory environment, and the toxin production and the determination of aflatoxin B 1 were carried out with the rice powder producing medium. As a result, the two strains produced aflatoxins B_1 had a low toxin production rate. Both strains contained 10μg / kg and 16.67% of toxigenic strains, as determined by the medium post-fixation thin layer method. Some data were provided to prevent food poisoning and potential chronic effects in humans and animals And reference. The experimental results are summarized below. Twelve strains of Aspergillus flavus were inoculated with rice flour medium for toxigenicity, and yellow
