    摘要: Supplemented mixotrophic method. A mixotrophic fermentation method is disclosed including providing a naturally acetogenic organism; providing a fermentation medium comprising a carbon source and a supplemented non-sugar reductant; and culturing the organism in the fermentation medium, where both the carbon source and the non-sugar reductant are metabolized and a fermentation broth is formed, which contains at least one carbon-containing bioproduct.

    摘要: Provided is a method for the production of refined, low-acetal ethanol, comprising providing a fermentation product produced by fermentation of a carbon source with an ethanol-producing organism, which fermentation product comprises between 30% wt and 99% wt ethanol, between 70% wt and 1% wt water and between 20 and 2000 parts per million acetal; contacting said fermentation product with an acid catalyst, whereby at least 20% of the acetal hydrolyses to form a hydrolysis product comprising ethanol, water, acetaldehyde and optionally residual acetal; and distilling said hydrolysis product, whereby distilled, low-acetal ethanol is formed.

    摘要: Provided is a method for producing an ester of butyric acid from an acid mixture, comprising contacting an aqueous carboxylic acid mixture comprising butyric acid and at least one additional carboxylic acid selected from the group consisting of formic acid, acetic acid, propionic acid, lactic acid, hydroxybutyric acid and combinations thereof, wherein at least 30% of the total amount of acids in the aqueous carboxylic acid mixture are in free acid form, with a liquid extractant having a Hildebrand solubility parameter of less than 25 MPa(1/2); separating a resultant butyric acid-comprising extract from a residual aqueous phase; contacting a resultant separated butyric acid-comprising extract with an alkanol in the presence of an acid catalyst, to form a product comprising an ester of butyric acid and alkanol and optionally water; wherein when water is formed, separating water to provide a separated product comprising an ester of butyric acid.
