Abstract:

Twelve strains of meat lactic starter cultures (Pediococcus spp. and Lactobacillus plantarum) were found to produce hydrogen peroxide in vitro. The (cumulative) amounts of H2O2 produced were measured through the peroxidative action of catalase on H2O2 and oxidation of added formate to CO2 by the H2O2‐catalase complex formed. There was a problem in building a calibration curve for converting values of formate oxidation into amounts of H2O2, either by adding H2O2 directly to the assay mixture or having it produced via a glucose‐glucose oxidase system.
