Versuchsvorschrift

At the completion of the reaction (100% conversion of nitrile), the product mixture was decanted from the biocatalyst beads, and additional distilled, deionized water, 0.2 mL of 0.20 M calcium acetate buffer (pH 7.0, 2.0 mM final calcium ion concentration in reaction mixture) and 10, 20, 40 or 60 mmol of acrylonitrile, methacrylonitrile, or 3-hydroxy-valeronitrile mixed with the reaction heel (immobilized-cell catalyst and remaining product mixture from the first reaction) at 25° C. or 35° C. At the completion of the second reaction, the product mixture was decanted and a third reaction performed as before. The reaction time, product yield for acrylamide, methacrylamide, or 3-hydroxyvaleramide, and the percent recovered biocatalyst activity for each recycle reaction is listed in Table 11 below.
