食物和动物饲料的微生物学用平行法计数B葡萄糖苷酸酶阳性埃希氏菌属大肠杆菌第2部分:在44度C时使用薄膜和5-溴4-氯3-吲哚基-B-D葡萄糖苷酸的菌落计数技术
摘要:This part of ISO 16649 specifies a horizontal method for the enumeration of β-glucuronidase-positive Escherichia coli in products intended for human consumption or for the feeding of animals. It uses a colony-count technique at 44 ℃ on a solid medium containing a chromogenic ingredient for detection of the enzyme p-glucuronidase. WARNING —Strains of Escherichia coli which do not grow at 44 ℃ and, in particular, those that are β-glucuronidase negative, such as Escherichia coli 0157, will not be detected.
