Title: Production of liquid enzyme agent
Inventor: INOUE TAKESHI
IPC: C12N9/00
Filed: 1992-08-03
Abstract: PURPOSE:To obtain a uniformly concentrated liquid enzyme agent not precipitating enzyme crystal for a long period of time by raising pH of an enzyme solution to give an enzyme solution containing no enzyme crystal, lowering the pH of the enzyme solution in the presence of a salt having a specific concentration and precipitating the enzyme in an amorphous state. CONSTITUTION:The pH of a solution of an enzyme (e.g. thermolysin produced by Bacillus thermoproteolyticus; protease similar to thermolysin produced by Bacillus steareotheromophilus) in which enzyme crystal may or may not exist is raised to >=10 (usually pH11-12) to dissolve the enzyme crystal. A salt (chloride, acetate or sulfate of alkali metal, alkaline earth metal or ammonium) is added to make the final concentration 15-30% and the pH of the enzyme solution is lowered to 5-8 (preferably pH6-7) to give the objective liquid enzyme agent.
