Bromocresol Purple Dextros Broth , 250g

Description: 

The coliform group of bacteria is the principal indicator of suitability of water for domestic, industrial or other uses. The coliform group density has been established as a criterion of the degree of pollu tion and thus of sanitary quality. Faecal Streptococci and Enterococci are also indicators of faecal pollution (1). Where it is claimed that drinking water has been processed for safety, the finding of such organism demonstrates a failure of the process. I t is a valuable bacterial indicator for determining the extent of fecal contamination of recreational surface waters or drinking water (2).

Bromo Cresol Purple Broth with Dextrose is used for the identification of Escherichia coli and coliforms from water. It is used for enrichment and determining the titre of coliforms in the bacteriological analysis of drinking water (3, 4). The medium contains peptic digest of animal tissue and meat extract, which supplies the essential nutrients for E. coli and other coliforms. Sodium chloride maintains the osmotic equilibrium of the medium. Dextrose upon fermentation by coliforms produce acid and is indicated by the pH indicator bromo cresol purple. It turns yellow at acidic pH
