Low-temperature α-amylase (AAL) is produced by submerged fermentation of Bacillus subtilis followed by purification and formulation. The product is not as heat-stable as thermostable α-amylase, bringing the benefit of easy inactivation.
This product belongs to family of hydrolytic enzyme, attacking α-1.4 glycosidic bond in starch, glycogen, etc.,
producing dextrin, oligosaccharides a small amount of glucose.
