Patents by Inventor Richard David Haigh

Richard David Haigh has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Bacterial growth enhancer
    Patent number: 9796958
    Abstract: We describe the production and use of an extract obtained from Musa spp., preferably from bananas, in the promotion of growth of Gram-positive bacteria such as lactic acid bacteria. The extract is also useful for growth enhancement of environmentally-stressed Gram negative bacteria. Fermented foods containing such extracts are also described.
    Type: Grant
    Filed: November 7, 2006
    Date of Patent: October 24, 2017
    Assignee: Plant Bioscience Limited
    Inventors: Primrose Pamela Elaine Freestone, Richard David Haigh, Mark Lyte
  • BACTERIAL GROWTH INDUCER
    Publication number: 20100099132
    Abstract: The present invention relates to methods of preparing bacterial growth inducers, and in particular to novel bacterial growth inducers/resuscitators prepared by such methods. The invention extends to various applications of such growth inducers, for example in clinical and environmental diagnostics, in reviving not immediately culturable (NIC) bacteria, and in the analyses of microbial populations in blood, food and soil samples.

  • Method for inducing bacterial growth using autoinducers
    Patent number: 6649398
    Abstract: A bacterial autoinducer and method for isolating and purifying a bacterial autoinducer form a sample comprising the steps of collecting a sample containing the autoinducer, fractionating the sample to isolate fractions corresponding to molecular weights of approximately 300-1500 Dalton, and eluting the isolate on an anion-exchange chromatographic column and selecting the faction containing the autoinducer.
    Type: Grant
    Filed: July 12, 2001
    Date of Patent: November 18, 2003
    Assignee: University of Leicester
    Inventors: Primrose Pamela Elaine Freestone, Peter Humphrey Williams, Mark Lyte, Richard David Haigh
  • E. coli, Salmonella or Hafnia autoinducers
    Publication number: 20020068330
    Abstract: The present invention concerns a novel bacterial autoinducer, methods of its manufacture, isolation and purification, uses of autoinducer isolated and purified using same, and the uses of the autoinducer.
