  • Process for hydrolyzing starch without pH adjustment
    Publication number: 20080145900
    Abstract: An alpha-amylase enzyme obtained from Bacillus acidocaldarius species is utilized to liquefy starch at a pH as low as 3.0 without the need to add thermostabilizing agents such as calcium. The alpha-amylase produces acceptable DE yields in a single liquefaction step and does not need to be inactivated prior to conducting saccharification which can proceed without adjustment of the pH of the liquefact. Alternatively, a secondary liquefaction process can be utilized, in which case two additions of the alpha-amylase are used resulting in a combined low dosage of the enzyme.

  • Thermal stabilization of alpha-amylase
    Patent number: 4717662
    Abstract: Disclosed is a method for enhancing the thermal stability of microbial alpha-amylase. The method involves adding a stabilizing amount of an amphiphile to the enzyme in its aqueous solution. Also included within the scope of the invention is the stabilized alpha-amylase formulation and its use in the liquefaction of starch.
