  • Patent number: 10047363
    Abstract: A nucleic acid molecule comprises a nucleotide sequence: as shown in SEQ ID No. 1, which is the complement of SEQ ID No. 1, which is degenerate with SEQ ID No. 1, or which has at least 85% sequence identity with SEQ ID No. 1, or which is a part of such a sequence. The nucleic acid molecule encodes or is a complementary to a nucleic acid molecule encoding one or more polypeptides, or comprises or is complementary to a nucleic acid molecule comprising one or more genetic elements, having functional activity in the synthesis of a polyketide-based or macrolactam molecule. The nucleic acid molecule may be used to prepare a modified BE-14106 biosynthetic gene cluster for the preparation of a modified BE-14106 molecule.

  • Publication number: 20150126467
    Abstract: The disclosure relates to use of alginate oligomers to enhance the effects of antifungal agents. The invention provides a method to improve the efficacy of an antifungal agent against a fungus, said method comprising using said antifungal agent together with an alginate oligomer. The fungus may be on an animate or inanimate surface and both medical and non-medical uses and methods are provided. In one aspect the invention provides an alginate oligomer for use together with at least one antifungal agent in treating a subject infected, suspected to be infected, or at risk of infection, with a fungus. In another aspect the method can be used to combat fungal contamination of a site e.g., for disinfection and cleaning purposes.

  • Publication number: 20130269451
    Abstract: A fluid transfer system or fast-loop is provided for transferring a liquid sample from a liquid source to a remote liquid sample analyser. The system comprises a capillary that connects the liquid source and the liquid analyser. When the system is used, liquid flows from the liquid source to the liquid analyser via the capillary. The capillary may form a looped circuit between the liquid source and the liquid analyser.

  • Publication number: 20100323408
    Abstract: It is described biologically pure bacterial cultures of mutant strains of Pseudomonas fluorescens, which produces large amounts of alginate. The alginate may contain a certain determined content of mannuronate and guluronate residues, possible presence and determined level of acetyl groups in the alginate, and a desired molecular weight of the alginate. Also high yielding mutants with regulation of alginate production, is described. The invention further provides methods for producing new mutant strains of Pseudomonas fluorescens and variants thereof, and use of the resulting strains in alginate production.
