🔬 Product Overview
Dextrose Casein Peptone Agar (DCPA) is a general-purpose medium designed for the growth, isolation, and enumeration of heterotrophic bacteria from food, water, environmental, and industrial samples. Casein peptone provides a rich source of amino acids and peptides, while dextrose serves as an easily utilizable carbohydrate.
The medium is suitable for total viable counts, colony morphology studies, and routine quality control in microbiology laboratories.

Solid surface for colony isolation
Casein enzymic hydrolysate supplies amino acids, peptides, and growth factors essential for bacterial proliferation. Dextrose provides a readily available energy source. Additional peptones or extracts (where present) enhance the nutrient profile. Agar solidifies the medium, allowing for isolation and morphological evaluation of colonies.
