The foodproof Beer Screening 1 LyoKit is a real-time PCR test for detecting beer spoilage bacteria DNA from Lactobacillus, Pediococcus, Pectinatus, and Megasphaera genera in beer samples, enrichment broth, and pitching yeast. This multiplex PCR assay specifically identifies Lactobacillus brevis and detects hop-tolerance genes horA and horC, enabling comprehensive screening of potential beer spoilers. The lyophilized format ensures stability and convenient handling while delivering results for up to 94 samples per run.
