NEOGEN Dextrose Tryptone Agar, 5 kg
Supplier: NEOGEN 700003337
Dextrose Tryptone Agar is used for isolation of mesophilic or thermophilic spoilage microorganisms from food and is not intended for use in the diagnosis of disease or other conditions in humans.Dextrose Tryptone Agar evolved from research by Williams, while studying the cultivation and enumeration of thermophilic bacteria caused by “flat-sour” spoilage of canned foods. In the 1930’s, the National Canners Association specified the use of Dextrose Tryptone Agar for isolating “flat sour” organisms from food products. “Flat sour” spoilage of canned foods is caused by Bacillus coagulans (Bacillus thermoacidurans). Bacterial growth results in a 0.3 – 0.5 drop in pH, while ends of the can remain flat. B. coagulans is a soil microorganism, found in canned tomato products and dairy products. Conditions favorable for organism growth can result in spoilage of food products.For more information visit https://www.neogen.com/solutions/Microbiology/dextrose-tryptone-agar
