Isolation and purification of a hydrolyzed milk allergy source beta-lactoglobulin protease

TL;DR: In this article, an isolation and purification of a hydrolyzed milk allergy source beta-lactoglobulin protease and an application thereof was described, and a Bacillus subtilis S7 was used to produce the protease.

Abstract: The invention discloses an isolation and purification of a hydrolyzed milk allergy source beta-lactoglobulin protease and an application thereof, and provides a Bacillus subtilis S7 producing a hydrolyzed milk allergen source beta-lactoglobulin protease. The protease produced by the fermentation and purifying of the Bacillus subtilis S7 can effectively degrade the beta-lactoglobulin in the milk protein, the protease output has high yield, the fermentation method is simple, a fermentation medium is simple, the fermentation cycle is short, and the sensitization can be effectively eliminated.
