    Abstract: A modular multi bag propagation unit to facilitate easy handling of the process elements and efficient use of equipment, services and resources for small-scale yeast production is disclosed. The equipment and method comprises the steps of producing and inoculating a bag, propagating yeast within the bag, and concentrating the yeast in a section of the bag that is the removed from the remainder of the bag whilst not exposing any portion of the yeast therein to an external environment. Consequently the yeast may be propagated in the very bag in which it is prepared for transportation and transported or shipped to the purchaser. In order to remove only the bag containing the most concentrated slurry of yeast, a smaller bag is heat-sealed off of the larger bag, thereby creating a separate bag for the living sediment but that is still the bag in which the sediment was propagated.

  • Patent number: 8323717
    Abstract: The method of producing baker's yeast involves producing yeast from a substrate composed of date syrup (Dips) diluted by molasses in sufficient quantity to lower the concentration of organic acids present in the date syrup that are toxic to yeast to safe levels, preferably a 1:1 mixture (w/w) of date syrup (Dips) and molasses. The substrate is inoculated with viable cells of Saccharomyces cerevisiae yeast and placed in a bioreactor or fermentation vessel. The yeast is produced by a fed-batch process to ensure continuous yeast production and prevent or minimize the production of alcohol by the yeast, additional increments of the substrate being added about hourly for the duration (about 12 hours) of the yeast propagation process. The process produces baker's yeast comparable in quality to yeast produced from a pure molasses substrate for such purposes as making bread, and in sufficient quantity to be practical for industrial production.

  • Publication number: 20120295332
    Abstract: Oxygen is delivered into a liquid contained within a vessel. Oxygen-rich gas is introduced at an inner mixing region of a vessel toward an agitating element for dissolving some of the oxygen into the liquid. Air is introduced to the liquid at a location different from where the oxygen-rich gas is introduced, minimizing coalescing of bubbles of the oxygen-rich gas and air bubbles. Running the agitating element in the vessel may induce mixing of the liquid and improve oxygen dissolution. Movement of the air bubbles can also generate a mixing effect on the liquid, yet independent from mixing caused by the agitating element. In some embodiments, currents produced by the agitating element are asymmetric with respect to a vertical axis of the vessel. Air bubbles may also form an asymmetric configuration of bubbles about the vertical axis.

  • Publication number: 20120295333
    Abstract: Biological liquid substances in a disposable bioreactor or a disposable fermentor is enriched with a dissolved gas such as oxygen. The gas is provided to the liquid in meeting growth needs of biomass within the disposable vessel. The liquid is processed through a bubble forming element such as a supersonic mixer, a membrane sparger, or the like, to form a gas-liquid dispersion. The dispersion has a high interfacial surface area for facilitating gas dissolution in the liquid. Receptacles of the disposable vessel may be coupled (e.g., magnetically) to one or more processing devices (e.g., motors, pumps, gas sources) outside of the disposable vessel so that components within the disposable vessel are able to perform functions suitable for furthering reaction and/or fermentation processes.

  • Patent number: 8293518
    Abstract: This invention relates to a novel microorganism that efficiently produces a dodecahydro-3a,6,6,9a-tetramethylnaphtho[2,1-b]furan intermediate using sclareol as a substrate. As a result of concentrated studies, a plurality of novel microorganisms having properties of interest that are not classified as conventional microorganisms were isolated and identified. The novel microorganism of the present invention belongs to Ascomycetes and has the ability of producing a dodecahydro-3a,6,6,9a-tetramethylnaphtho[2,1-b]furan intermediate using sclareol as a substrate. Such microorganism of Ascomycetes represents a new finding and it can be effective for producing dodecahydro-3a,6,6,9a-tetramethylnaphtho[2,1-b]furan and an intermediate thereof.
