Modified Nocive Brewers Bacteria Agar Base is a medium used for the detection of beer spoilage bacteria. This medium contains a wide variety of nutrients including pancreatic digest of casein, yeast extract, beef extract, dextrose and maltose. These nutrients favour the growth of spoilage microorganisms in beer and other samples. Potassium acetate (instead of sodium acetate) makes the medium less inhibitory for the growth of spoilage bacteria that deteriorate beer and other samples. Polysorbate 80 is incorporated to neutralize phenols, hexachlorophene and formalin. L-Cysteine hydrochloride is the reducing agent. Disodium phosphate act as a buffer system. Bacteriological agar is the solidifying agent.
