The present invention is directed to renewable compositions derived from fermentation of biomass, and integrated methods of preparing such compositions.


This invention is directed to methods for recovery of C3-C6 alcohols from dilute aqueous solutions, such as fermentation broths. Such methods provide improved volumetric productivity for the fermentation and allows recovery of the alcohol. Such methods also allow for reduced energy use in the production and drying of spent fermentation broth due to increased effective concentration of the alcohol product by the simultaneous fermentation and recovery process which increases the quantity of alcohol produced and recovered per quantity of fermentation broth dried. Thus, the invention allows for production and recovery of C3-C6 alcohols at low capital and reduced operating costs.


Methods for producing a biofuel are provided. Also provided are biocatalysts that convert a feedstock to a biofuel.

This invention is directed to methods for recovery of C3-C6 alcohols. The recovery process advantageously utilizes the immiscible properties of a first phase liquid and a second phase liquid to separate the liquids prior to processing C3-C6 alcohols to recovery. The invention is also directed to C3-C6 alcohol-containing compositions.
