  • Patent number: 11618909
    Abstract: The present invention provides an acid-tolerant Saccharomyces cerevisiae strain and use thereof. By using exogenously added malic acid as a stress, an acid-tolerant mutant S. cerevisiae strain MTPfo-4 is obtained by directed evolution screening in the laboratory, which tolerates a minimum pH of 2.44. The mutant strain MTPfo-4, tolerant to multiple organic acids, has an increased tolerance to exogenous malic acid of up to 86.6 g/L. The mutant strain MTPfo-4 obtained is further identified. The mutant strain grows stably and well, and can tolerate a variety of organic acids (lactic acid, malic acid, succinic acid, fumaric acid, citric acid, gluconic acid, and tartaric acid). It also has a strong tolerance to inorganic acids (HCl and H3PO4). This is difficult to achieve in the existing research and reports of S. cerevisiae. The strain is intended to be used as an acid-tolerant chassis cell factory for producing various short-chain organic acids.

  • Patent number: 9371537
    Abstract: The present invention relates generally to the field of molecular biology and concerns a method for enhancing yield-related traits in plants by modulating expression in a plant of a nucleic acid encoding an SGT1 polypeptide, or a CLC-pKG polypeptide, or a HD-hydrolase-like polypeptide. The present invention also concerns plants having modulated expression of a nucleic acid encoding an SGT1 polypeptide, or a CLC-pKG polypeptide, or a HD-hydrolase-like polypeptide, which plants have enhanced yield-related traits relative to corresponding wild type plants or other control plants. The invention also provides constructs useful in the methods of the invention.

  • Patent number: 9321806
    Abstract: A novel method for processing soluble plant leaf proteins is described. While leaf proteins are considered potentially the most abundant source of protein in nature, the lack of efficient processing techniques for leaf proteins has limited their commercial use. The method described in this patent provides a means of extracting and purifying leaf proteins from plants which is suitable for leaf protein production on an industrial scale.

  • Patent number: 9051586
    Abstract: The present invention relates to a technique for capturing carbon dioxide and converting the carbon dioxide to carbonate minerals using a recombinant whole cell biocatalyst expressing carbonic anhydrase. More particularly, the present invention relates to a composition for capturing carbon dioxide and a method for capturing carbon dioxide using the composition, which composition comprises a whole cell of a transformant formed with a vector including a nucleic acid encoding a recombinant carbonic anhydrase; a cell lysate or its fraction of the whole cell; or a recombinant carbonic anhydrase isolated from the whole cell. Further, the present invention relates to a composition and method for converting the carbon dioxide to carbonate minerals using the carbon dioxide capturing composition.
