When you examine a sample for the presence of anaerobic beer spoilers, all working steps during the whole analysis must be focused on avoiding any contact of oxygen with the sample. Ideally, the sample is put into the incubation vessel direct at the place of sampling, followed by immediate incubation in a non-oxygen atmosphere.
FastOrange® B Ready-to-Use Tubes are ideal for simple sampling.
FastOrange® B Bouillon is the liquid medium for the detection of anaerobic beer spoilers. Besides turbidity, they often produce their characteristic bad smell and a color change, too.
Membrane filtration for the detection of anaerobic microorganisms is only possible with special equipment and therefore not recommended for a standard lab. If equipment for anaerobic membrane filtration is available, filtered samples are enriched on FastOrange® B Agar plates.
