基本信息
| General description【一般描述】 |
Coliforms 100 is a chromogenic medium that provides easy-to-read, definitive positive results. It has a high nutritional quality of the peptones along with incorporated phosphate buffer that guarantees rapid growth of coliforms, while lauryl sulfate largely inhibits the accompanying flora (especially the Gram-positive). The chromogenic substrates X-GAL (cleaved by coliforms) and the fluorogenic substrate MUG (highly specific for
E. coli) allow for the simultaneous detection of total coliforms and
E. coli. The presence of total coliforms is indicated by a blue-green color of the broth and
E. coliby a blue fluorescence under UV-light. The optional 30-second indole reaction helps to accurately confirm the presence of
E. coli. ReadyCult
?tests are convenient, rapid and economical.
|
| Application【应用】 |
Coliforms 100 is a rapid
E. coli/Coliform test for drinking water. It is a selective enrichment broth used for the simultaneous presence / absence detection of total coliforms and
E. coliwithin the bacteriological water examination.
