Abstract
This invention is a process for producing a stable aqueous solution of acrylamide or methacrylamide by subjecting acrylonitrile or methacrylonitrile in water to the action of microorganisms having a nitrilasic activity, which is characterized in that said microorganisms are treated with a water-soluble dialdehyde to thereby inhibit polymerization of the acrylamide or methacrylamide produced.
