acumedia* D/E Neutralizing Agar

• Intended Use: D/E Neutralizing Agar is used for the isolation of microorganisms from sanitized environmental surfaces.
• Product Summary: D/E Neutralizing Agar was developed by Dey and Engley to neutralize a broad spectrum of disinfectants and
preservative antimicrobial chemicals, including quaternary ammonium compounds, phenolics, iodine, chlorine preparations,
mercurials, formaldehyde, and glutaraldehyde. D/E Neutralizing media neutralize higher concentrations of residual antimicrobials
when compared with other standard neutralizing formulations, such as Letheen media, Thioglycollate media, and Neutralizing
Buffer.

Total neutralization of disinfectants is critical. Disinfectant residues can result in a false negative (no-growth) test. D/E Neutralizing Agar effectively neutralize the inhibitory action of disinfectant carryover, allowing differentiation between bacteriostasis and true bactericidal action of disinfectant chemicals. This is a critical characteristic to consider when evaluating a disinfectant. D/E Neutralizing Agar is recommended for use in disinfectant evaluations, environmental sampling (swab and contact plate methods), and testing of water-miscible cosmetics
