一般描述

Universal Beer Agar is a base medium supplemented with beer. Its characteristics are closer to natural environmental conditions found in a typical brewery. Thus, it supports the growth of more lactic acid bacteria and yields larger colonies in a shorter time than other brewer’s media. The addition of beer gives the medium some selectivity to the organisms adapted to existing conditions in the brewery. Hop and alcohol inhibit the growth of many other microorganisms, which are not adapted to the beer matrix.

应用

Universal Beer Agar is suitable for culturing spoilage microorganisms of significance in the brewing industry (bacteria like Lactobacillus, Pediococcus, Acetobacter, and yeasts).

制备说明

Suspend 62.16 g in 750 ml of distilled water. Heat to boiling to dissolve the medium completely. Add 250 ml beer, without degassing, to the hot medium and mix gently. Dispense as desired and sterilize by autoclaving at 121°C for 10 minutes. If required, add 1 ug/ml (Cat. No. 01810) of Cycloheximide to sterile medium prior to dispensing.

附注

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.
