A process for mechanical destructuring of cellulosic 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 biomass, with or without saccharification and/or in-feed glycosyl hydrolase enzymes, may be used in feed applications.

High force and high stress destructuring of cellulosic biomass

A process for purifying 1,3-propanediol from the fermentation broth of a culturedthat has been bioengineered to synthesize 1,3-propanediol from sugar is provided. The basic process entails filtration, ion exchange and distillation of the fermentation broth product stream, preferably including chemical reduction of the product during the distillation procedure. Also provided are highly purified compositions of 1,3-propanediol.

Purification of biologically-produced 1,3-propanediol

A process is provided for producing glycolic acid from formaldehyde and hydrogen cyanide. More specifically, heat-treated formaldehyde and hydrogen cyanide are reacted to produce glycolonitrile having low concentrations of impurities. The glycolonitrile is subsequently converted to an aqueous solution of ammonium glycolate using an enzyme catalyst having nitrilase activity derived from72W (ATCC 57746). Glycolic acid is recovered in the form of the acid or salt from the aqueous ammonium glycolate solution using a variety of methods described herein.

Process for producing glycolic acid from formaldehyde and hydrogen cyanide

The present invention relates to a method for obtaining a carboxylic acid ester from an aqueous solution of the corresponding carboxylic acid ammonium salt using alcoholysis. The recovered carboxylic acid ester may be subsequently hydrolyzed to produce the corresponding carboxylic acid.

Method to produce a carboxylic acid ester from a carboxylic acid ammonium salt by alcoholysis

The present invention relates to a high yield process to prepare high purity crystalline glycolic acid using a multi-loop crystallization process characterized by high liquid and/or solid recycle, said process suitable for large scale purification and producing high purity glycolic acid with low diglycolic acid content.

Multi-stage glycolic acid crystallization

The invention discloses a hydrogenation process for removing impurities and controlling acid for use in downstream processing of biochemically-derived 1,3-propanediol. Preferably, the biochemically-derived 1,3-propanediol, before the contacting, has an initial color and, after the contracting, has a color that is lower than the initial color.
