Characterization of pectolytic enzymes From several fungi causing post‐harvest decay of citrus fruits From culture filtrates of Penicillium digitatum Sacc., Trichoderma viride Penz., Phomopsis citri (Faw.) cf. Diaporthe citri (Faw.) Wolf, and Colletotrichum gloeosporioides Penz. endo‐polygalacturonase and endo‐polymethylgalacturonase have been isolated. Both enzymes were active under acid conditions only. The last named fungus additionally produced pectic acid‐transeliminase, the activity was found under alkaline conditions.
