  • Patent number: 9765374
    Abstract: A fungal alpha-amylase is provided from Aspergillus fumigatus (AfAmyl). AfAmyl has an optimal pH of 3.5 and is operable at 30-75 degrees C., allowing the enzyme to be used in combination with a glucoamylase and an isoamylase 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 alpha-amylase or glucoamylase. AfAmyl also catalyzes the saccharification of starch substrates to an oligosaccharide composition significantly enriched in DP2 and (DPI+DP2) compared to the products of saccharification catalyzed by an alpha-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.

  • Publication number: 20160040202
    Abstract: A fungal alpha-amylase is provided from Aspergillus fumigatus (AfAmy1). AfAmy1 has an optimal pH of 3.5 and is operable at 30-75 degrees C., allowing the enzyme to be used in combination with a glucoamylase and a pullulanase 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 alpha-amylase or glucoamylase. AfAmy1 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 alpha-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.

  • Publication number: 20160010128
    Abstract: A fungal alpha-amylase is provided from Aspergillus terreus (AtAmyl). AtAmyl has an optimal pH of 4.5 and is operable at 30 75 degrees C., allowing the enzyme to be used in combination with a glucoamylase and a pullulanase 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 alpha-amylase or glucoamylase.

  • Patent number: 9029116
    Abstract: The present invention relates to glucoamylase variants. In particular, the invention relates to variants in the starch binding domain (SBD) of a glucoamylase. The invention also relates to variants having altered properties (e.g., improved thermostability and/or increased specific activity) as compared to a corresponding parent glucoamylase. The present invention also provides enzyme compositions comprising the variant glucoamylases; DNA constructs comprising polynucleotides encoding the variants; and methods of producing the glucoamylase variants in host cells.
