M-DEXTROSE TRYPTONE BROTH

Bacillus species includes many thermophilic bacteria which can enter milk from various sources like farm or from poorly cleaned equipments in the processing plant. These bacteria grow rapidly in milk or other dairy products that are held at high temperature for long periods. Flat-sour spoilage is sour spoilage of food products without formation of gas. Dextrose Tryptone Agar can be modified into M-Dextrose Tryptone Broth. It is used for cultivation of variety of microorganisms and thus called non-selective medium used M-Dextrose Tryptone Broth is used by Olson et al for determining total counts on samples of milk passed through welded milk lines.
