  • Microbiological production of polyesters having C.sub.8 and/or C.sub.10 monomer repeat units
    Patent number: 5387513
    Abstract: A microbiological process, capable of producing polymers comprising monomer repeat units of the structure--O.CH((CH.sub.2).sub.x CH.sub.3).CH.sub.2.--CO--wherein x is particularly 6 from glucose, novel polymers produced through the process and new strains of Pseudomonas for use in the process.
    Type: Grant
    Filed: December 16, 1993
    Date of Patent: February 7, 1995
    Assignee: Zeneca Limited
    Inventors: Alistair J. Anderson, Edwin A. Dawes, Geoffrey W. Haywood, David Byrom

  • Copolymer production
    Patent number: 5264546
    Abstract: A process for the synthesis of copolymers comprising 3-hydroxybutyrate (HB) and 3-hydroxyvalerate (HV) units by the cultivation of certain strains of Corynebacterium, and Rhodococcus, some of which are novel on a substrate containing e.g. glucose. The process can also be used to produce the previously unknown homopolymer of HV by using a substrate of valeric acid.
    Type: Grant
