ABSTRACT:
A process for the decomposition of acrylamide using an amidase (acrylamide amido hydrolyase) enzyme in which the enzyme has been heated to a temperature in the range 40.degree. to 80.degree. to induce increased activity of the enzyme. A method for preparing the enzyme and a process for producing acrylic acid are also claimed. The process for the decomposition of acrylamide is useful in particular for reducing the level of unreacted monomer associated with homo- and hetero-polymers of acrylamide. A temperature in the range 50.degree. to 62.degree. is particularly preferred for heating.
