To determine a favorable medium for detecting fungal extracellular protease, a plate method was examined. In this study, 12 fungal strains were tested with 4 different types of Czapek Dox agar medium containing skim milk, and the clear zones around the colonies were compared on the different types of medium. Among them, 9 strains produced extracellular proteases. Triton X-100 was required to detect an extracellular protease fromAlternaria alternata, while in case of Peniciliium frequentans, saccharose was required. It was found that the media supplemented with both Triton X-100 and saccharose gave acceptable results in terms of extracellular protease detection.
