說明
一般描述
Escherichia coli broth is suitable for the selective enrichment, enumeration, ａnd confirmation of coliform bacteria. The lactose content of this medium favors the growth of lactose-positive bacteria, especially coliform bacteria, ａnd E. coli. The bile salts inhibit the growth of Gram-positive bacteria or microorganisms that are not adapted to the intestinal environment. Lactose-positive bacteria metabolize lactose with gas formation.
應用
Escherichia coli broth is suitable for the selective enrichment, enumeration, ａnd confirmation of coliform bacteria from food ａnd animal feed, ａnd other materials.
