A note on catalase enhanced recovery of acid injured cells of Gram negative bacteria and its consequences for the assessment of the lethality of L‐lactic acid decontamination of raw meat surfaces

Abstract
Addition of catalase (150 units/ml) to a rich infusion agar used for solid medium repair of acid injured pathogenic Enterobacteriaceae increased the recovery of such populations by 1–2 log cycles entailing an equal size reduction in the true lethality of this mode of processing for safety.
