Tricarboxylic Acid (e.g., Citric Acid, Etc.) Patents (Class 435/144)
  • Patent number: 11525149
    Abstract: A non-naturally occurring eukaryotic or prokaryotic organism includes one or more gene disruptions occurring in genes encoding enzymes imparting increased fumarate, malate or acrylate production in the organism when the gene disruption reduces an activity of the enzyme. The one or more gene disruptions confers increased production of acrylate onto the organism. Organisms that produce acrylate have an acrylate pathway that at least one exogenous nucleic acid encoding an acrylate pathway enzyme expressed in a sufficient amount to produce acrylate, the acrylate pathway comprising a decarboxylase. Methods of producing fumarate, malate or acrylate include culturing these organisms.

  • Publication number: 20150147786
    Abstract: A process for mechanical destructuring of starch-based biomass was developed that makes use of a short application of high compression, impact, and shearing forces. The biomass may be destructured using a specific energy input that is less than 40% of the total combustible energy of the biomass. The destructured starch-based biomass, with or without saccharification and/or in-feed glycosyl hydrolase enzymes, may be used in feed applications. The destructured starch-based may saccharified to produce syrups and fermentable sugars, and for production of products including ethanol using a biocatalyst.

    Abstract: A process for production of C5 and C6 sugar enriched syrups from lignocellulosic biomass and fermentation products therefrom is described. A lignocellulosic biomass is treated with a C1-C2 acid (e.g., acetic acid) with washing thereof with a C1-C2 acid miscible organic solvent, (e.g., ethyl acetate). A soluble hemicellulose and lignin enriched fraction is obtained separately from a cellulose pulp enriched fraction and lignin is removed from the soluble hemicellulose fraction. These fractions contain acylated (e.g., acetylated) cellulose and hemicellulose, which are deacylated by treatment with an alkali and/or with an acetyl esterase enzyme. The deacylated fractions are then digested with suitable cellulolytic and/or hemicellulolytic enzymes, preferably in the presence of non-ionic detergent to yield the C5 and C6 enriched syrups.

    Abstract: A process for the fermentative production of at least one organic compound having at least 3 C atoms or having at least 2 C atoms and at least one 1 N atom, comprising the following steps: a1) milling a starch feedstock, thus obtaining a millbase which comprises at least part of the nonstarchy solid constituents of the starch feedstock; a2) suspending the millbase in an aqueous liquid and hydrolysis of the starch portion in the millbase by enzymatic liquefaction and, if appropriate, subsequent saccharification, whereby a first liquid (1) which comprises mono- or oligosaccharides is obtained; and b) addition of the liquid (1) which comprises mono- or oligosaccharides together with metabolizable mono-, di- or oligosaccharides or together with a composition which comprises metabolizable mono-, di- or oligosaccharide in a concentration of at least 50% by weight and which is essentially free from solids which are insoluble in water to a fermentation medium comprising a microorganism which is capable of overproduc

  • Patent number: 8728762
    Abstract: The invention relates to a method for producing at least one organic compound comprising at least 3 C-atoms or at least 2 C-atoms and at least 1 N-atom by fermentation. Said method comprises the following steps: i) a starch source is ground in order to obtain a grinding material which contains at least one part of the non-starch containing solid components of the starch source; ii) the grinding material is suspended in an aqueous liquid in an amount such that the dry mass content in the suspension is at least 45 wt.
