    Abstract: The present invention relates to a mutated pyruvate carboxylase gene from Corynebacterium . The mutant pyruvate carboxylase gene encodes a pyruvate carboxylase enzyme which is resistant to feedback inhibition from aspartic acid. The present invention also relates to a method of replacing the wild-type pyruvate carboxylase gene in Corynebacterium with this feedback-resistant pyruvate carboxylase gene. The present invention further relates to methods of the production of amino acids, preferably lysine, comprising the use of this mutant pyruvate carboxylase enzyme in microorganisms.

    Abstract: A method of preparing a non-wood fiber paper strengthening product is disclosed. The method comprises placing an additive in an aqueous alkaline medium, wherein the additive comprises a hydroxycarboxylic acid, and mixing a non-wood fiber material with the placed additive in the aqueous alkaline medium to form a mixture, wherein the non-wood fiber material comprises starch, protein and fiber, wherein the additive, starch, protein, and fiber of the non-wood fiber material, and metal ions of the alkaline medium become physically crosslinked resulting in a non-wood fiber paper strengthening product. In an aspect, the non-wood fiber paper strengthening product is used in making a paper product wherein the paper product has greater strength than the same paper product made with native starch or chemically modified starch instead of the non-wood fiber paper strengthening product.

    Abstract: Processes for the oxidation of carbohydrate dehydration products, such as furanics that can be oxidized to the bio-based monomer 2,5-furandicarboxylic acid (FDCA), are disclosed, according to which certain co-feeds, having been discovered to impart a beneficial reaction stabilizing effect, are oxidized together with the carbohydrate dehydration products. This can advantageously counteract, in whole or in part, detrimental effects of humin impurities present in oxidation feed, with such impurities having been generated as byproducts of the upstream dehydrating step. An important co-feed is para-xylene that can be co-oxidized to form the petroleum-based monomer terephthalic acid (TPA), such that co-processing can beneficially yield two valuable monomers, while improving performance, particularly in terms of reaction stability, over comparable processes in which only the first monomer is produced. Related aspects involve opportunities for retrofitting existing monomer production facilities to enable co-processing of carbohydrate dehydration products that can lead to the above-noted advantages.

    Abstract: Disclosed herein are processing methods for producing a physically modified starch and for producing a physically modified flour and/or starch flour mixture. The starch process comprises adding at least one salt or additive to a starch, adjusting the pH of the starch to alkaline, and dewatering the starch using a filter to obtain filtered solids. The process further comprises drying the filtered solids, spreading a layer of dried filtered solids on a surface, and heating the dried filtered solids while on the surface to a temperature of about 100° C to 190° C to obtain the physically modified starch. In an embodiment, the flour and/or starch/flour mixture process comprises preparing a thermally inhibited flours and/or starch/flour mixtures starting with or without additives, pH adjustment, followed by heat treating the flour and/or starch/flour mixtures directly to obtain the physically modified flour and/or starch flour mixture.
