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 H 2 O 2 . Whilst keeping the same principle, the use of a novel growth medium and of the chromogen tetramethyl‐benzidine allows the detection of H 2 O 2 production by strains previously classified as non‐producers.
