NBB® Prepared Culture Media for Beer (Döhler)

Ready-to-use agar or broth

• Excellent identification of beer spoilage organisms
• Use with filtered or unfiltered beer and yeast culture
• Fast results – optimized nutrient combinations for fast growth of spoiling micro-organisms
• Simple screening – Simple and reliable visual control through a clear change in the indicator color from red to yellow, for easy quantitative and qualitative analysis in almost any NBB® culture media
• Increased selectivity – Inhibition of the harmless accompanying flora and culture yeast necessary for the brewing process for optimized detection of beverage-spoiling micro-organisms

Suitable for detection in:

• unfiltered beers containing yeast
• filtered beers
• yeast samples
• water and rinsing water
• airborne bacteria collection samples
• swab samples for hygiene monitoring

Detection of spoiling micro-organisms in all types of beer samples, such as Lactobacilli, Pectinatus and Megasphaera. Get clear, fast and reliable detection, even for a very low level of contamination in a large sample volume.

NBB uses special growth promotion components and nutrients optimally tailored to beer spoiling micro-organisms. Döhler exclusively uses raw materials of non-animal origin, thus eliminating the risk of animal materials entering the beer quality control process. A series of comprehensive functional tests examine the quality of the NBB culture media with a special panel of test strains, which were all isolated in breweries.

NBB-A, Agar

Solid agar medium for pouring agar plate after simple liquefaction.

• Can be used for membrane filtration, swab and pour plate method as well as for airborne microorganism collection
• Simple, visual screening by means of an indicator change from red to yellow

NBB-B, Broth

Liquid culture media with indicator dye for detection of beer spoiling microorganisms in yeast samples or as an enrichment medium.

• Direct use of liquid medium
• Simple, visual screening by an indicator change from red to yellow

NBB-C, Concentrated Broth

Liquid culture medium with enhanced selectivity through the addition of yeast-cloudy beer samples.

• Simply added to the beer sample for analysis
• Final microscopic inspection, no indicator verification

NBB-B-AM, Broth

Liquid culture medium for detection of indicator bacteria from biofilms.

• Simple hygiene monitoring for weak point analyses and trending
• Sampling by means of smear swabs at critical points throughout the production process
• Direct use of liquid medium - ready-to-use in sterile tubes or sterile bottle for individual portioning
• Simple, visual screening by means of an indicator change from red to yellow
