the unculturable microorganisms did not have a significant effect on the catalase activity determination.
Moreover, compared with the conventional agar plate method, the proposed catalase activity-based method is more rapid in detecting the microbial spoilage of stored grains
From the catalase activities of pure mold and agro-product samples containing the same number of molds, we found that the catalase activities in grain samples were all higher than those from pure molds, probably because of the catalase activities from unculturable microorganisms in the modified Czapek's medium
