    Abstract: The present invention relates to a method for producing a polyacrylamide solution having increased viscosity. In particular, the present invention is related to the separation of a biocatalyst from an aqueous acrylamide solution prepared utilizing the biocatalyst prior to polymerization of the aqueous acrylamide solution to polyacrylamide. A polyacrylamide solution having in creased viscosity is well suited to be used in tertiary oil recovery. Accordingly, the present application provides means and methods to crucially improve the quality of polyacrylamide solutions for use in tertiary oil recovery.
