General description

This MRS Agar is free of animal derived material. It is recommended for the isolation and cultivation of Lactobacillus species.

Application

MRS Agar, Vegitone has been used for culturing yogurt to analyze lactic acid bacteria (LAB). It has also been used in culturing of Lactobacillus reuteri colonies.

Preparation Note

Suspend 62.2 g in 1000 ml distilled water containing 1 ml polysorbate 80 (TWEEN® 80; Cat. No. P8074). Boil to dissolve the medium completely and mix thoroughly. Sterilize by autoclaving at 15 lbs pressure (121°C) for 15 minutes. If necessary adjust the pH with glacial acetic acid after sterilization.

Other Notes

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.
