Abstract: A fungal α-amylase is provided from Aspergillus clavatus (AcAmyl). AcAmyl has an optimal pH of 4.5 and is operable at 30-75° C., allowing the enzyme to be used in combination with a glucoamylase in a saccharification reaction. This obviates the necessity of running a saccharification reaction as a batch process, where the pH and temperature must be readjusted for optimal use of the α-amylase or glucoamylase. AcAmyl also catalyzes the saccharification of starch substrates to an oligosaccharide composition significantly enriched in DP2 and (DP1+DP2) compared to the products of saccharification catalyzed by an α-amylase from Aspergillus kawachii. This facilitates the utilization of the oligosaccharide composition by a fermenting organism in a simultaneous saccharification and fermentation process, for example.
Abstract translation: 真菌α-淀粉酶由曲霉菌（AcAmyl）提供。 AcAmyl具有4.5的最佳pH，并且在30-75℃下可操作，允许酶在糖化反应中与葡糖淀粉酶组合使用。 这消除了作为间歇法运行糖化反应的必要性，其中必须重新调节pH和温度以最佳地使用α-淀粉酶或葡糖淀粉酶。 与由川曲霉α-淀粉酶催化的糖化产物相比，AcAmyl还催化淀粉底物对显着富集DP2和（DP1 + DP2）的寡糖组合物的糖化。 这有助于例如在同时糖化和发酵过程中由发酵生物体利用寡糖组合物。

Abstract: A fungal α-amylase is provided from Aspergillus clavatus (AcAmy1). AcAmy1 has an optimal pH of 4.5 and is operable at 30-75° C., allowing the enzyme to be used in combination with a glucoamylase in a saccharification reaction. This obviates the necessity of running a saccharification reaction as a batch process, where the pH and temperature must be readjusted for optimal use of the α-amylase or glucoamylase.

IPC: C12P7/14
Abstract: A conversion process provides using different co-cultured cell lines to express different sets of enzymes catalyzing the same process. For example, in a Simultaneous Saccharification and Co-Fermentation (SSCF) process, a starch substrate is converted to alcohol by contacting the substrate with yeast and Aspergillus niger cells. Because A. niger expresses an endogenous glucoamylase and alpha-amylase, these enzymes do not need to be added during the SSCF process.
