Method for the separation of extracellular amylase and protease produced during the fermentation of enzyme producing microorganisms

摘要

Extracellular protease and amylase coproduced during the fermentation of a microorganism capable of producing them are separated by the addition of polyethyleneglycol and a cationic epihalohydrin/polyamine copolymer or dextran polymer to the fermentation medium and allowing the polymers to phase separate to form a protease rich phase and an amylase rich phase.
