Bacterial Amylase - 100mlPlease note that none of our enzymes are to be considered as being of Food Grade Standard and are not fit for human consumption. They are only suitable for use in education.Working Concentration: 0.5 - 1%pH range: 4 - 8Temperature range: 20 - 60°CSubstrate: 2% StarchProduct: Maltose DextrinsSource: B. subtilisContains reducing sugarsIt'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 solutionPectinase supplied as 100ml - 1ml diluted to 100ml gives a 1% solution.Glossary:pH - Recommended range for maximum activityTemperature - recommended range for maximum activityWorking 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 concentrationProduct - substance produced by breakdown of the substrateSource - origin of the Enzyme
