It is quite possible to have a positive reaction in a glucose carbohydrate broth and yet a negative reaction in a glucose use methyl red test. This is due to: O If amino acids are metabolized this will interfere with the methyl red reaction glucose makes acid in a Phenol red test but neutral products in a methyl red test phenol red can detect single acid production but methyl red requires more than one acid produced. methyl red cannot detect the types of acid produced from glucose
