Lmda Agar (Lees Multi-Differential Agar) 1084 Condalab

LMDA Agar is a nutrient medium that detects most organisms commonly found in the brewery. Using beer as a medium is often not useful due to the lack of development of bacteria as there are a low quantity of available nutrients, the presence of alcohol, carbon dioxide and sulphur dioxide, as well as low conservation temperatures. Beer filtration and pasteurization phases also contribute to the stabilization of the product against microorganisms.

The number of genera and species which usually contaminate it is limited. As is the case with wild yeasts, the contaminating bacteria cause turbidity and generate anomalous smells. Acid producing bacteria can be identified by the presence of a clear zone around the colonies. Further identification is facilitated by the characteristic colour reactions. cycloheximide can be added to the medium to inhibit the growth of culture yeast. If you wish to detect yeasts, don’t add cycloheximide and incubate under the same conditions (time and temp) in aerobic conditions.
