  • Patent number: 11773355
    Abstract: A system and method for directly transferring fermentation carbon dioxide by-product to a greenhouse are disclosed. A three-way valve receives the carbon dioxide by-product from fermentation vessels in a fermentation facility, and either directs the carbon dioxide by-product to a proximately located greenhouse or diverts the carbon dioxide by-product to the external environment based on greenhouse carbon dioxide concentration levels that are monitored by sensors communicatively coupled to the valve. For example, if the concentration levels are below a threshold, the sensors may transmit a signal to the valve to direct the carbon dioxide by-product to the greenhouse; otherwise, if the concentration levels are at or above the threshold, the carbon dioxide by-product may be diverted to the external environment. The threshold may be a carbon dioxide concentration level determined to be optimal for photosynthetic efficiencies based on a number and/or type of the plants contained within the greenhouse.

  • Patent number: 10165732
    Abstract: A system, device and method for delivering CO2 or other gases to plants in fields, orchards, vineyards and the like. A stake with a windbreak structure and gaseous emitters on the upwind side creates a leeward wind eddy surrounding a plant, such as an orchards sapling. This establishes and maintains a gaseous microclimate beneficial to the plant. The device delivers CO2 gas to a plant in an agricultural field, orchard, grove, orchard of the like. The device includes an elongated base adapted to be adjustably placed on the ground a predetermined distance from the plant, upwind of the plant. A wind foil is adjustably connected to the base along its elongated length. The wind foil has a curvilinear geometry with a first face having a generally convex configuration, and a second face having a generally concave configuration. An emitter assembly is disposed on the second face of the wind foil. A gas supply conduit is communicatively connected to the emitter and adapted to be connected to a gas supply.

    Abstract: Provided is a method for producing a yeast containing glutamic acid at a high concentration. In the method for culturing a yeast, a yeast in a stationary growth phase is subjected to liquid culture under the conditions that the pH of a liquid medium is 7.5 or higher and lower than 11. After the pH of the liquid medium for the yeast in a stationary growth phase is adjusted to 7.5 or higher and lower than 11, the yeast is further cultured, whereby a yeast with a high glutamic acid content can be produced. In the invention, as the yeast, Saccharomyces cerevisiae or Candida utilis can be used. Therefore, by using the yeast with a high glutamic acid content obtained by the above-said method and the extract obtained by extraction from the yeast, a seasoning composition and a food or drink with a high glutamic acid content can be provided.

The obtained yeast Ge-32K contains the higher content of the organic bio-germanium than the conventional yeast as produced by using germanium dioxide.

  • Publication number: 20130273587
    Abstract: Provided are compositions and methods related to heme transporters and high-throughput methods of identifying agents that can modulate heme transporters. An approach for identifying a modulator of a eukaryotic heme transporter involves adding a toxic heme analog and at least one test agent to a culture of cells, wherein the cells express a recombinant heterologous eukaryotic heme transporter. The cells are incubated with the toxic heme analog and the test agent for a period of time. A change in toxic effect of the toxic heme analog relative to a control is indicative that the test agent is a modulator of the eukaryotic heme transporter. Heme transporter agonists and antagonists can be identified. Also provided is a cell culture comprising a plurality of cells which express a recombinant heterologous eukaryotic heme transporter. The plurality of cells are divided into a plurality of reaction chambers, each of which may contain a test agent, and may further contain a toxic heme analog.
