157:7 Plating medium for the isolation and detection of E. coli O157:H7

摘要

The present invention sample E. coli O157: relates to a solid plate medium for detection and isolation of the H7, E. coli of the present invention in detail O157: H7 for the component for the detection medium is (1) growth of the microorganisms; (2) agar; (3) sorbitol; (4) beta-galactosidase chromogenic substrate for the second; (5) Beta - The first chromogenic substrate for a glucuronidase; 6-beta-glucuronidase as a glue to promote the color reaction is the Pico arsenide component; And (7) containing erythritol and the like Other E. coli O157: H7 components which inhibit the growth of other bacteria; a pH indicator; And Escherichia coli O157: may contain a carbon source, such as that is not used by H7. E. coli of the present invention O157: H7 for the detection medium is E. coli O157: H7, as well as the selectivity for the solid, it is economical to use the expensive color-developing substrate in a minimum amount.
