Beer spoilage by Lactobacillus brevis and / or Lactobacillus lindneri: Molecular diagnosis (PCR); Molecular identification (sequencing); Quantitative culture.

Tests in IVAMI:

  • Detection of Lactobacillus brevis and Lactobacillus lindneri of samples for specific for each species PCR.
  • If it is positive for Lactobacillus brevis, detecting the presence of Lactobacillus brevis of beer degrader.
  • Should be positive for Lactobacillus brevis degrader beer and / or Lactobaillus lindneri, proceed with quantitative culture if desired.

Cost of testing

  • Identification of Lactobacillus brevis by PCR and verification by sequencing.
  • Identification of Lactobacillus lindneri by PCR and sequencing verification by
  • Identification of strains of Lactobacillus brevis, causing degradation by detecting the corresponding gene by PCR (only if positive for Lactobacillus brevis).
  • Quantitative plating specific means for Lactobacillus spp., Incubated in anaerobiosis (only if positive for Lactobacillus brevis and / or Lactobacillus lindneri).
