Description

Hiveg is selective mediun recommended for the simultaneous detection of Escherichia coli and total coliforms in water and food samples. The medium composition helps even the sub lethally injured coliforms to grow rapidly. Sodium lauryl sulphate inhibits gram-positive organisms. To confirm Escherichia coli, add a drop of Kovacs reagent (R008) on the dark-blue to violet colony. Formation of cherry-red colour indicates positive reaction.
