说明

General description

The DNase Test Agar with Toluidine Blue is a specialized microbiological medium used to detect deoxyribonuclease (DNase) activity in bacteria and fungi. It incorporates toluidine blue as an indicator, which produces a distinct color change when DNase activity is present. This medium is particularly effective for differentiating and identifying nonpigmented Serratia species. Tryptose in the formulation provides essential nutrients, while DNase activity depolymerizes DNA, triggering a bright pink reaction due to the metachromatic properties of toluidine blue. However, some Staphylococcus strains may experience growth inhibition on this medium because of the toluidine blue. Additional confirmatory tests are recommended for accurate identification.
