    Abstract: The present invention provides a process for producing fermentable sugar or a fermentation product from a lignocellulosic feedstock. The process comprises leaching the lignocellulosic feedstock with an aqueous solution to remove at least potassium salts from the lignocellulosic feedstock and without significantly hydrolyzing hemicellulose and cellulose, thereby producing a leached feedstock and leachate. The leachate is removed from the leachate and concentrated. The leached feedstock is hydrolyzed to produce fermentable sugar, which may be fermented to produce a fermentation broth comprising the fermentation product. The concentrated leachate is recirculated to one or more stages in the process involving alkali addition to adjust the pH of a process stream.

  • Publication number: 20120005788
    Abstract: Provided is a method for producing xylonic acid from xylose with a recombinant fungal strain that is genetically modified to express a xylose dehydrogenase gene, which is able to convert xylose to xylonolactone, which is spontaneously or enzymatically hydrolysed to xylonic acid. The xylonic acid is excreted outside the host cell. Xylonate production may be coupled with xylitol production. Alternatively, if xylitol production is not desired, its production is reduced by removing the aldose reductase (or specific xylose reductase) enzyme, which converts xylose to xylitol. Expression of a heterologous lactonase encoding gene may result in higher acid concentrations. The method is suitable for producing xylonic acid from a hemicellulose hydrolysate such as hydrolysed lignocellulosic plant biomass.

  • Patent number: 7579175
    Abstract: The present invention provides a process for economically producing N-acetylneuraminic acid without using expensive materials such as pyruvic acid and phosphoenolpyruvic acid. The process comprises: allowing (i) a culture of a microorganism having N-acetylneuraminic acid aldolase activity or N-acetylneuraminic acid synthetase activity, or a treated matter of the culture, (ii) a culture of a microorganism capable of producing pyruvic acid or a treated matter of the culture, or a culture of a microorganism capable of producing phosphoenolpyruvic acid or a treated matter of the culture, (iii) N-acetylmannosamine, and (iv) an energy source which is necessary for the formation of pyruvic acid or phosphoenolpyruvic acid to be present in an aqueous medium to form and accumulate N-acetylneuraminic acid in the aqueous medium; and recovering N-acetylneuraminic acid from the aqueous medium.

  • Patent number: 7517675
    Abstract: A method of oxidising carbohydrates and/or carbohydrate derivatives having primary alcohol groups comprising contacting a reaction medium containing said carbohydrates and/or carbohydrate derivatives with a nitroxy radical mediator and a peroxidase enzyme, characterized in that the initial reaction medium contains at least 10% by weight carbohydrates and/or carbohydrate derivatives, in that the peroxidase enzyme is an oilseed peroxidase and in that a hydroperoxide and an alkali compound are gradually added to the reaction medium such that its pH is maintained at between 3.5 and 10.0 (pH-Stat); use of said method in a process for producing gluconic acid, glucaric acid and/or D-glucuronolactone.

  • Patent number: 7510861
    Abstract: A novel gluconate dehydratase derived from Achromobacter xylosoxidans and a gene encoding the gluconate dehydratase are provided. By reacting the gluconate dehydratase or a transformed cell containing the gene with an aldonic acid, the corresponding 2-keto-3-deoxyaldonic acid can be efficiently produced.
