Use for the selective isolation and enumeration of significant contaminating bacteria and yeasts encountered in wort and beer.
Universal Beer Agar is presented as a basal medium to
which beer alone or beer and cycloheximide may be added for the detection and
culture of microbial contaminants in beer. The medium is based on the formula
developed by Kozulis and Page, who recommended that beer must be incorporated
in the medium in order to increase selectivity by stimulating the growth of
beer spoilage organisms. The presence of hop constituents and alcohol
eliminates many airborne contaminants not originating in pitching yeasts, wort
or beer; thus minimizing false positive results.
Universal Beer Agar supports the growth of Lactobacilli, Pediococci, Acetobacter,
Zymomonas spp. and wild yeast strains which may be found infecting
the pitching yeast, the cooled wort, or during fermentation or storage of the
finished beer.
Also available as: UBA Agar with Cycloheximide
