說明
一般描述
GranuCult® plus Universal beer agar is a basal, non-selective agar rich in nutrients that support the growth ａnd recovery of microorganisms. The incorporation of beer in the medium adds hop constituents ａnd alcohol, which eliminate many airborne contaminants not originating from pitching yeasts, wort, or beer, thus minimizing false positive results. Also, it stimulates the growth of beer spoilage organisms, such as Lactobacilli, Pediococci, Acetobacter, Zymomonas spp., ａnd wild yeast strains, which may be found infecting the pitching yeasts, the cooled wort or during fermentation or storage of the finished beer.

Cycloheximide (1 mg/L) may be added to detect bacterial contaminants in pitching yeasts.
應(yīng)用
GranuCult® plus Universal beer agar is suitable for the detection of beer spoilage microorganisms.
