  • Patent number: 5578382
    Abstract: A supported or cast film of a polyhydroxyalkanoate polymer, such as a polyhydroxybutyrate/valerate polymer, can be prepared by applying a layer of molten polymer to a cool (typically 4.degree. to 20.degree. C.) surface not substantially above the glass transition temperature of the polymer, so as to form a solid, glassy film with a high density of nucleation sites; subsequently the temperature of the film so formed is raised, for example to 40.degree. C. or more, towards the optimum temperature for growth of the polymer's spherulites effectively separating the film formation/nucleation step from the crystallisation step (growth of spherulites around the nucleation sites). Smaller crystallites are formed, and the film has improved barrier properties.

  • Patent number: 5571904
    Abstract: Three similar gene sequences are provided, the sequences being shown in the drawings, which are recovered from male flower parts of maize, specifically anther tissue.

  • Patent number: 5563065
    Abstract: A process for the cultivation in continuous culture of a filamentous microorganism in a culture medium to which are supplied sources of carbon and other appropriate nutrients. The carbon or another nutrient source is supplied in an amount limiting to the growth of the culture and constitutes a limiting nutrient thereto. The development of an unwanted variant of the filamentous microorganism is restricted or delayed by supplying a first nutrient source to the culture as a limiting nutrient, and thus changing the nutrient supply to the culture in a manner such that a second nutrient source replaces the first nutrient source as the limiting nutrient.
