  • 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.

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.

  • Patent number: 9021826
    Abstract: A water energy conversion system includes a control unit, a first gas-water energy conversion device, a second gas-water energy conversion device, a water supply device, a storage tank and a heat source unit. Water for different purposes is supplied by the water supply device that collects and transmits various kinds of water resources. Operations of the storage tank as well as the first and second gas-water energy conversion devices are based on water as the basis and a carrier of energy conversion to provide effective energy conversion and recycling. By further employing the heat source unit, high-efficiency cooling, heat dissipation or heat absorption can be achieved with minimal power and water consumption. Thus, the water energy conversion system is applicable for energy conversion, energy regulation and supply for air of indoors and outdoors of a building to realize effects of water storage and supply, anti-flooding, and energy saving and storage.
