Activating Compound

Activating Compound Comment Organism Structure
2-mercaptoethanol 2 mM, 119% of initial activity Alicyclobacillus sp.

Application

Application Comment Organism
food industry application in malting and brewing industry. Under simulated mashing conditions, addition of Agl9A at 20 U/ml or a commercial xylanase at 200 U/ml reduce the filtration rate by 26.71% and 20.21%, respectively, and viscosity by 6.12% and 4.78%, respectively. Combined use of Agl9A at 10 U/ml and the xylanase at 100 U/ml even more effectively reduces the filtration rate by 31.73% and viscosity by 8.79% Alicyclobacillus sp.
