Commercial Grade Liquid
It’s good practice to store enzymes in a refrigerator (5°C approx.). This should give a shelf life of 12 months without significant loss of activity.
All enzymes, as supplied, should be considered as 100% (unless otherwise specified) for example:
Cellulase is supplied as 2g powder – 1g in 100ml gives a 1% working solution
Pectinase supplied as 100ml – 1ml diluted to 100ml gives a 1% solution
Glossary:
pH – Recommended range for maximum activity
Temperature – recommended range for maximum activity
Working Concentration – dilution of the Enzyme (as supplied) to this level should give an acceptable reaction time.
Substrate – substance to be reacted with the Enzyme, and appropriate concentration
Product – substance produced by breakdown of the substrate
Source – origin of the Enzyme
