    摘要: A process for the bioconversion of a nitrile to its corresponding amide product, particularly acrylonitrile to acrylamide which is used for forming polymers. The process uses a thermophilic bacterium having a nitrile hydratase activity that is constitutively expressed, activated by cobalt ions, stable at 60.degree. C., and is most active between 20.degree. C. to 70.degree. C. with optimum activity at 55.degree. C. Alternatively, the process uses the enzyme extracted from the thermophilic bacterium to convert a nitrile to its amide product. The genes encoding nitrile hydratase and amidase are described in which the former is useful for the conversion of an nitrile to its amide and the later is useful for the conversion of an amide to its acid.

    摘要: Disclosed herein is a printed circuit board including an optical waveguide and a method of manufacturing the board. In the board, the optical waveguide includes a metal layer extending portion integrally connected to a metal layer constituting a mirror formed in the optical waveguide. Since the method of the present invention creates the mirror using electroless plating, which is typically used in a process of manufacturing general printed circuit boards, it is suitable for the manufacture of printed circuit boards having a large area, and the mirror has high reflectivity and is efficient in terms of material consumption.
