Screening for Phenoloxidases from Edible Mushrooms

Abstract

A screening test for phenoloxidases from edible mushrooms was done on potato dextrose agar plates that contained phenolic chemicals. Many edible mushrooms showed positive reactions on the agar plates. Among them, Auricularia auricula-judae, Clitocybe nebularis, Lentinus edodes, Pholiota aurivella, and Pseudohiatula oshimae produced a considerable amount of phenoloxidases, and these enzymes showed maximum activities in the acidic pH region.
