  • Patent number: 5443963
    Abstract: The present invention exploits the herein first reported, empirical observation that even though staphylococci produce the enzyme, beta-glucosidase, this genus of bacteria is not able to produce a metabolite that will enzymatically react with 5-bromo-4-chloro-3-indolyl-beta-D-glucopyranoside, a substrate commonly used to detect the presence of beta-glucosidase produced by other bacteria. In view of this unexpected observation, one embodiment of the present invention includes a selective medium containing inhibitors to enhance staphylococci growth as well as a first glucopyranoside substrate, such as 5-bromo-4-chloro-3-indolyl-beta-D-glucopyranoside, and a second phosphatase substrate, such as 6-chloro-3-indolylphosphate or 5-bromo-6-chloro-3-indolylphosphate.

  • Patent number: 5403722
    Abstract: The present invention relates to a method and apparatus for counting the number of microorganism colonies present on a disposable microorganism culturing device having a substantially planar substrate. The preferred apparatus of the present invention includes an LED bar illuminating the surface of the substrate and a linear array of SELFOC lenses which focus the light reflected off of the substrate onto a linear CCD sensor array. The CCD sensor array is connected to a microprocessor which analyzes the raster-scanned data using the preferred algorithm. The preferred algorithm uses the sigma-shaped neighborhood for image processing. The preferred algorithm passes the sigma region across the image in a raster-scanned order to detect object starts and merges which yield a colony count for a scanned microorganism culturing device.

  • Patent number: 5284759
    Abstract: Meta-hydroxyphenylacetylenes are produced from phenyl-substituted ketal or acetal precursors. Using biotransformation processes, these precursors serve as substrates that are converted to cis-dihydrodiol intermediates. The cis-dihydrodiols can be converted chemically to the corresponding meta-substituted compounds, e.g., meta-substituted phenols, and then to m-hydroxyphenylacetylene, which is an intermediate needed to produce acetylene-terminated resins. The biotransformation step employs arene-2,3-dioxygenase in intra- or extra- cellular form.

  • Patent number: 5262484
    Abstract: Graft copolymers and processes for the preparation thereof are provided. The copolymers comprise a base polymer having grafted thereto a monomeric 2-alkenyl azlactone. The surface properties of the graft copolymers can be modified by binding thereto nucleophilic reagents comprising further functional groups with desired properties. Further, the amount of azlactone available at the surface of a graft copolymer for binding to such nucleophilic reagents can be controlled by selecting a surface against which the graft copolymer is formed. The graft copolymers exhibit desirable thermoplastic, melt flow, and adhesion properties and are particularly useful for immobilizing proteins. Methods of immunoassay based on the immobilization of proteins are also disclosed. Another utility of the graft copolymers involves the compatibilizing of immiscible polymer blends.
