DEXTROSE TRYPTONE BROTH, MODIFIED

Canned foods are most often prone to flat-sour spoilage due to contamination by either mesophilic or thermophilic aerobic spore-formers. Williams evolved Dextrose Tryptone Agar, a suitable medium for cultivation and enumeration of the thermophilic bacteria. It is also recommended for general cultural studies by Cameron and other associations. Dextrose Tryptone Broth, Modified is more nutritious and well buffered than Dextrose Tryptone Broth due to inclusion of yeast extract and dipotassium phosphate. Dextrose Tryptone Broth, Modified is similar in composition to Dextrose Tryptone Agar, Modified, except agar. This medium is useful for enumeration of mesophilic organisms, thermophiles in cereals and cereal products, dehydrated fruits and vegetables and spices.
