DNAse Test Agar (Deoxyribonuclease Activity) is used to differentiate microorganisms using correlation between coagulase positive and DNase activity. This differential medium is especially recommended for the identification of pathogenic staphylococci. Casein peptone and soy peptone provide nitrogen, vitamins, minerals and amino acids essential for growth. Sodium chloride supplies essential electrolytes for transport and osmotic balance. Deoxyribonucleic acid enables the detection of DNase that depolymerize DNA. Bacteriological agar is the solidifying agent.
