Abstract

A new type of p-Benzoquinone activated support (agarose, polyvinyl alcohol, chitosan) which can be stored for more than one year, is described. Coupling yields of 10-95% were obtained for various compounds (propylamine, serum albumin, alpha-amylase). A retained activity of 150% for the immobilized laccase, was obtained. This peculiar result is probably due to the presence of hydroquinone groups on the support, which, as a substrate of laccase, can generate a simultancous affinity retention of the enzyme. © 1989 Science & Technology Letters.
