In case the item is thought to have antimicrobial action, an inactivating agent could possibly be added on the diluents.

VALIDATION OF NEUTRALIZATION METHODS—RECOVERY COMPARISONS A validated method for neutralizing the antimicrobial Houses of a product ought to meet two standards: neutralizer efficacy and neutralizer toxicity. The validation analyze paperwork which the neutralization method employed is efficient in inhibiting the antimicrobial properties of the merchandise (neutralizer efficacy) with no impairing the Restoration of feasible microorganisms (neutralizer toxicity). Validation protocols could meet these two criteria by comparing recovery final results for therapy teams.

Duration and temperature of incubation may also be important components of a microbiological test method. Classical methodologies employing large nutrient media are generally incubated at 30
