Abstract: | The published plate methods for the detection of hydrogen peroxide-producing lactic acid bacteria, which employ horseradish peroxidase and a chromogen, clearly fail to detect all the organisms that produce H2O2. Whilst keeping the same principle, the use of a novel growth medium and of the chromogen tetramethyl-benzidine allows the detection of H2O2 production by strains previously classified as non-producers. |
