General description

Lactose TTC Agar with Tergitol-7 is recommended as a selective and differential medium for the recovery of injured coliform organisms from chlorinated water by membrane filter technique.

Application

for detection and enumeration of coliform organisms from chlorinated water by membrane filter technique

Preparation Note

Suspend 53.85 g in 1000 ml distilled water. Heat to boiling to dissolve the medium completely. Sterilize by autoclaving at 121°C for 15 minutes. Cool to 45-50°C. Aseptically add 2.5 ml of 1% 2,3,5 Triphenyl Tetrazolium chloride (TTC) solution (Cat. No. 17779).

Footnote

We offer two media types: the superior granulated GranuCult® and the cost-efficient powdered NutriSelect® culture media, depending on your needs.
The designations basic, plus, or prime are added to indicate the quality control level, from basic quality control to standard QC plus to prime for full regulatory compliance.
