Pleurotus albidus: A new source of milk-clotting proteases

Researches have been done to discover new sources of microbial proteases with milk-clotting activity to replace the traditional rennet from calves. The aim of this study was to select a species of edible mushroom as milk-clotting enzymes producer using the submerged fermentation technology. From the six species evaluated, Pleurotus albidus was the one that expressed the highest value of coagulant ratio (21.60). The...
