Abstract
A "repair-detection" procedure consisting of pour plating of food samples with Trypticase soy agar, followed by 1-h repair incubation at room temperature and subsequent overlay with violet red bile agar, was found to be an effective method for the detection of injuried and uninjuried coliforms from dairy products. This method was relatively less effective for the detection of coliforms in many semipreserved foods as compared with dairy products, but more effective than the most-probable-number method.
摘要
一种“修复检测”程序，包括用胰蛋白胨大豆琼脂对食品样品进行倾注平板培养，然后在室温下进行1小时的修复培养，随后覆盖紫红胆盐琼脂，被发现是检测乳制品中受伤和未受伤大肠菌群的有效方法。与乳制品相比，该方法在检测许多半保藏食品中的大肠菌群时效果相对较差，但比最大可能数法更有效。
