  • Patent number: 11873445
    Abstract: Methods of natural gas production and carbon sequestration are provided. The method includes delivering a feedstock downhole to a coal reservoir, generating biogas within the coal reservoir, and harvesting the biogas. Another method for tracing the migration of biogas in a coal reservoir includes delivering a feedstock downhole to a coal reservoir, generating biogas that is isotopically differentiable from a background gas within the coal reservoir through microbial action, harvesting the biogas, analyzing the biogas from the coal reservoir at the injection well and at one or more offset wells within the same coal reservoir, detecting the biogas at the offset wells using isotopic differentiation, and mapping the migration of the biogas from the injection well to the offset wells using the biogas as an isotopic tracer.

  • Patent number: 6387683
    Abstract: The present invention provides a process for producing biologically active recombinant yeast protein disulfide isomerase, which includes the steps of: a) deleting, substituting, or adding one or more bases in a region encoding an endoplasmic reticulum retention signal in a gene encoding protein disulfide isomerase of yeast to modify the gene so as not to encode part or all of the endoplasmic reticulum retention signal; b) incorporating the modified gene into an expression vector; c) transforming host cells with the expression vector; and d) culturing the host cells transformed with the expression vector in a culture medium kept at a nearly neutral pH, thereby causing protein disulfide isomerase to be secreted in an active state outside the host cells. According to the process of the invention, recombinant yeast protein disulfide isomerase can be secreted in a large amount in a biologically active state into a culture medium, and can be collected by a simple purification method.

    Abstract: Flavorant compounds and compositions for food substances are prepared in a food-acceptable manner by bio-conversion of a cysteine S-complex with a food-acceptable micro-organism, particularly a yeast or filamentous fungus, which, upon incubation with the complex, splits the complex at a terminal carboxyl group in a beta position to yield a product including a thiol and at least one metabolite compound, and the product is isolated.

  • Patent number: 5688674
    Abstract: A metabolite, e.g., ethanol, is continuously produced from low cost carbohydrate substrates by a process which comprises pulverizing the carbohydrate substrate; liquefying and saccharifying the pulverized substrate; continuously fermenting the lique-saccharified substrate in a fermentor equipped with a moving filter, in the presence of flocculent biological cells maintained at a concentration ranging from 90 to 160 g/l by using the moving filter and a culture medium to produce a fermentation product mixture; and recovering the desired metabolite from the fermentation product mixture.

  • Patent number: 5650183
    Abstract: Refrigeratable yeast-leavened dough products are prepared that can be stored for extended periods of time at refrigeration temperatures. The dough composition and yeast strain are chosen to limit the total leavening action of the yeast by controlling the mount of substrate in the dough fermentable by the yeast. Dough compositions made in accordance with the invention are capable of being leavened at elevated temperatures, yet stored in a sealed container at refrigeration temperatures for extended periods of time. In one embodiment, a maltose negative yeast is used and sucrose or the like is added to the dough to serve as a fermentable substrate for the dough; this dough is suitable for storage times of up to 30 days or so.

  • Patent number: 5631145
    Abstract: A process for producing recombinant human serum albumin (HSA) which comprises culturing an HSA producing host prepared by gene manipulation techniques at a temperature of from 21.degree. to 29.degree. C. Culturing the HSA producing host under such a specified temperature condition makes it possible to increase productivity of HSA production, improve the growth yield of an HSA producing host, and reduce the degree of coloring in the HSA preparation.
