Thermo Scientific™ DNase Test Agar

Description

• Detect the deoxyribonuclease (DNase) activity in microorganisms with Thermo Scientific™ Remel™ DNase Test Agar
• In 1957, Jeffries et al
• developed a medium for demonstrating deoxyribonuclease (DNase) activity of microorganisms possessing this extracellular enzyme
• 1 Such microorganisms depolymerize DNA in the medium resulting in a clear zone around the colonies when the plate is flooded with 1N hydrochloric acid (HCl)
• DNase Test Agar has been recommended for identification of a variety of bacteria including staphylococci, enteric gram-negative bacilli, and pseudomonads
• 2-5 This is a solid medium used to detect the deoxyribonuclease (DNase) activity in microorganisms
• Easy- to-interpret: Positive test – after 1N HCl is added, a clear zone is formed around the growth line and the rest of the plate remain opaque
• Negative test – after 1N HCl is added, no clear zone is formed around the growth line and the entire plate is opaque
• Ready- to-use: convenience of prepared media
• DNase Test Agar contain casein and soy peptone that supply nitrogen, amino acids and peptides necessary for bacterial growth
• Sodium chloride provide essential electrolytes which maintain osmotic equilibrium

• Remel™ and Oxoid™ products are now part of the Thermo Scientific brand.
