说明
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.
应用
GranuCult® plus Universal beer agar is suitable for the detection of beer spoilage microorganisms.
特点和优势
GranuCult® offers superior granulated culture media
Safe and sustainable due to reduced risks associated with fine dust and toxic substance inhalation, resulting in a safer work environment
Excellent wettability, solubility, and free-flowing properties
Convenient, with minimal component separation and clumping, even under warm or humid conditions
High batch-to-batch reproducibility
Prolonged shelf life of up to five years
High number of test strains exceeding all regulatory demands
Granulation technology allows many supplements to be included, with no need to add these separately

其他说明
The color of the prepared basal medium is clear and slightly brown and that of the medium with added beer is determined by the color of the beer.
Do not use clumped or discolored medium.
Store plates in the refrigerator and protect them from daylight.
The shelf-life of prepared plates is approx. 1 week and 2 months for the medium dispensed into bottles when stored at 2-8°C.
