Description

一般描述

mTSB Broth with Novobiocin is suitable for the selective enrichment of enterohemorrhagic Escherichia coli (EHEC) in foods intended for human and animal consumption. The peptone provides amino acids and other complex nitrogenous substances. Glucose is a fermentable carbohydrate. Sodium chloride delivers osmotic balance. Bile salts inhibit the growth of Gram-positive accompanying bacterial flora. Di-potassium hydrogen phosphate is the buffering agent to stabilize the pH.mTSB is made selective for E. coli O157:H7 by adding bile salts in the media along with Novobiocin supplementation.

应用

用于食品中肠出血性大肠杆菌 (EHEC) 的选择性增菌。根据 USDA-FSIS 方法用于分离和鉴别肉类中的大肠杆菌 0157:H7。
