  • Zeaxanthin producing strains of Neospongiococcum Excentricum
    Patent number: 5360730
    Abstract: The present invention is directed toward a process for producing zeaxanthin which includes mutating algal microorganisms, selecting from said mutated microorganisms a microorganism capable of producing zeaxanthin, culturing the selected microorganism in an effective medium to produce zeaxanthin, and recovering zeaxanthin produced by the selected microorganism. The present invention also provides microorganisms capable of producing zeaxanthin, formulations containing zeaxanthin produced by the disclosed process and the use of such formulations to enhance pigmentation and to reduce damage caused by reactive oxygen species and phototoxic molecules.

  • Phenylalanine ammonia lyase-producing strains
    Patent number: 4757015
    Abstract: Phenylalanine ammonia-lyase (PAL) producing Rhodotorula graminis, high PAL specific activity, strain GX 6000 its progeny, and PAL producing mutants thereof can be utilized for phenylalanine production from cinnamate. In this strain, PAL can be induced synergistically by phenylalanine and leucine or isoleucine.

    Assignee: Genex Corporation
    Inventors: Steve A. Orndorff, Don R. Durham
  • Rhodotorula having desaturase enzymes
    Patent number: 4677072
    Abstract: A yeast culture medium contains glucose, yeast extract, buffers, alkaline earth metal salts, and antibiotics, has a pH of 4.3 to 4.7. Yeast strains of the genus Rhodotorula, obtained from water and soil samples, are useful as desaturase enzymes, especially for the conversion of oleic acid to linoleic acid in improved yields using the yeast culture medium.

  • Enzymatic catalyzed biocide system
    Patent number: 4478683
    Abstract: A method of killing and inhibiting the growth of microorganisms in industrial process streams comprises the addition of an enzymatically catalyzed biocide system utilizing a microbial or plant dehydrogenase enzyme such as peroxidase or laccase in the presence of an oxidant such as hydrogen peroxide or oxygen to oxidize phenolic compounds found in or added to the process streams to produce oxidation products that are toxic to microorganisms.

  • Enzymatic catalyzed biocide system
    Patent number: 4370199
    Abstract: A method of killing and inhibiting the growth of microorganisms in industrial process streams comprises the addition of an enzymatically catalyzed biocide system utilizing a microbial or plant dehydrogenase enzyme such as peroxidase or laccase in the presence of an oxidant such as hydrogen peroxide or oxygen to oxidize halide salts, or phenolic compounds found in or added to the process streams to produce oxidation products that are toxic to microorganisms.
