  • Process for preparing nutritional, therapeutic or organoleptic products from crude glycerol
    Patent number: 8802408
    Abstract: The present invention relates to a process for preparing a nutritional, therapeutic or organoleptic product by growing non-recombinant yeast under aerobic conditions, in a medium that includes crude glycerol, as one possible carbon source to produce a yeast product. The yeast product can be processed to obtain such nutritional, therapeutic or organoleptic products as yeast paste, yeast metabolites, carbohydrates, proteins, functional proteins, nucleotides, yeast autolysates, yeast extract, yeast cell walls, beta-glucans, mannans or a product derived from a mineralized yeast product.
    Type: Grant
    Filed: January 16, 2009
    Date of Patent: August 12, 2014
    Assignee: Bio Processing Australia Pty Ltd.
    Inventors: Robin Fieldhouse, Donald Finlay MacLennan, David Graham MacLennan, Mary Elizabeth MacLennan
  • Ethanol fermentation process and products
    Patent number: 8158396
    Abstract: The present invention provides a novel process for ethanol fermentation which uses a high concentration of fresh yeast to co produce ethanol and good quality yeast.
    Type: Grant

  • Microbiological production of protein
    Patent number: 3989594
    Abstract: Growth of bacteria belonging to new species of genera Pseudomonas, Microcyclus and Hyphomicrobium upon culture media comprising sources of assimilable carbon, for example oxygenated hydrocarbons, and inorganic nutrients to produce protein compositions and/or other fermentation products, for example amino acids. The protein compositions produced are suitable for use as protein supplements in human and animal foods.
