Application

Application Comment Organism
food industry limit dextrinase activity is of particular importance for the brewing industry as the branched dextrins produced after the action of alpha-amylase on starch are not fermentable and represent a loss of potential ethanol production Hordeum vulgare

additional information in response to gibberellin produced by the embryo the aleurone layer synthesizes hydrolases that are secreted to the endosperm for degradation of storage products. The release of limit dextrinase to culture supernatant is significantly delayed and coincides with a general loss of protein from the aleurone layer. The enzyme is synthesized as an inactive bound form and is converted to an active free form during germination Hordeum vulgare
