With their special growth promotion components and nutrients optimised for beer spoiling microorganisms, NBB^® culture media offer fast detection, reliable results – even for a very low level of contamination in a large sample volume – and easy handling for efficient laboratory work. The colour change from red to yellow of an indicator added to almost any NBB^® culture media allows simple and reliable visual inspection. This makes both quantitative and qualitative analysis easier.

NBB^® is available in various product configurations:

• NBB-A – a solid agar medium for pouring plates after a simple melting process
• NBB-B – a liquid medium for detection of yeast samples
• NBB-C – a concentrated liquid medium in which the required selectivity is adjusted through the addition of yeast-cloudy beer samples
• NBB-B-BAM – a liquid medium for the detection of indicator microorganisms from biofilms during hygiene monitoring
