Abstract:
Taking three Pholiota adipose strain as materials,the activity changes of several extracellular enzymes were determined at different stages of development from three Pholiota adipose strains cultivated on cotton seed hull in bottle to reveal the features of activity changes of the same extracellular enzymes from different strains of the same edible fungi.The results indicated that all of the three strains had complete set of extracellular cellulose；the activity peaks of extracellular carboxymenthel cellulase (CMCase)，filter paper cellulase (FPase)，hemicellulase (HCase)，amylase and pectase from the three strains all appeared in the period between primordial formation and fruit-body maturity；there were no great changes in β-glucosidase activity from the three strains throughout its growth；the activity peaks of extracellular laccase from the three strains appeared in the period when substrates were fully colonized and in the period between first and second flush but their activities were low in the fruit-body maturity of both the first and second flush；and the extracellular peroxidase activities from the three strains remained high in the period of mycelial growth and then declined rapidly at the beginning of fruiting.It could be concluded that the activity changes of the same extracellular enzymes from the three strains were roughly the same.
