Title: Compartmentation distribution and regulation of enzymicbrowning in Flammulina velutipes
Abstract: The compartmentation distribution of polyphenol oxidase (PPO), peroxidase(POD) and catalase (CAT) activities in Flammulina velutipes appeared. The activitylevels were the lowest at the cap, high at the top of stipe, higher at the middleof stipe, and the highest at the bottom of stipe. Flammulina velutipes were treatedwith thiourea, sodium sulfite, Ca2+, and at high CO2, low O2 and low temperature,the activities of PPO, POD and CAT were inhibited. High 02, H202 and high temperatureenhanced the activities of PPO, POD and CAT. High N2 could not inhibit the activitiesof them.
