DEXTROSE TRYPTONE AGAR, 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 Agar, Modified is more nutritious and well buffered than Dextrose Tryptone Agar due to inclusion of yeast extract and dipotassium phosphate. Dextrose Tryptone Agar, Modified is used for the examination of canned food, sugar and starch for thermophilic bacteria such as Bacillus stearothermophillus (flat sourspoilage bacteria) and also for plate count of mesophilic or thermophilic aerobes in sweetening agents used in frozen desserts and for counts of aerobic microorganisms in liquid sugar.
