Description
D/E Neutralizing Broth is a recovery and neutralising medium for evaluating antiseptics and disinfectants and for environmental sampling.
Its neutralising system counteracts several antimicrobial groups: thioglycollate acts on mercurials, thiosulfate on iodine and chlorine, bisulfite on aldehydes, lecithin on quaternary ammonium compounds and polysorbate 80 on phenolics.
The broth helps distinguish bacteriostatic from bactericidal effects by allowing surviving microorganisms to recover after antimicrobial exposure. No numbered formal method reference is stated in the PDF.
