Provided herein are processes and microorganisms which utilize both protein hydrolysates and carbohydrates from biomass feedstocks to produce renewable hydrocarbon compositions. Advantages of the disclosed methods may be recognized in fuel blends comprising such hydrocarbon compositions.

Production of renewable hydrocarbon compositions

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

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.

Purification of biochemically derived 1,3-propanediol

Hydrogenation of biochemical derived 1,3 -propanediol

Disclosed is a process comprising contacting chemical 1,3-propanediol with hydrogen in the presence of a hydrogenation catalyst. Preferably, the chemical 1,3-propanediol, before the contacting has an initial color and, after the contacting, has a color that is lower than the initial color.

Hydrogenation of chemically derived 1,3-propanediol

Purification of chemical 1,3-propanediol

The invention concerns a process for the isolation of polyols, such as 1,3-propanediol, from a fermentation broth. Specifically, the invention discloses a process of adding base to the fermentation broth to raise the pH to a suitable level for reduction of impurity formation during isolation of the polyol.
