Descrizione

Applicazioni

Amylases from Aspergillus oryzae are used to prevent staling in the baking industry, clarify haze from fruit juices and alcoholic beverages, and produce glucose and maltose syrup products.

Versatile ligand for asymmetric catalysis. Ligand used for preparing Jacobsen′s catalyst suitable for enantioselective epoxidation of olefins lacking functional groups.

Lipases are used industrially for the resolution of chiral compounds and the transesterification production of biodiesel.

Azioni biochim/fisiol

α-amylase catalyzes the hydrolysis of internal α-1,4-O-glycosidic bonds in starches to release α-anomeric sugars.

Lipases catalyze the hydrolysis of triacylglycerols into glycerol and free fatty acids.
