Abstract: In an alcohol fermentation process, oil derived from biomass is chemically converted into an extractant available for in situ removal of a product alcohol such as butanol from a fermentation broth. The glycerides in the oil can be chemically converted into a reaction product, such as fatty acids, fatty alcohols, fatty amides, fatty acid methyl esters, fatty acid glycol esters, and hydroxylated triglycerides, and mixtures thereof, which forms a fermentation product extractant having a partition coefficient for a product alcohol greater than a partition coefficient of the oil of the biomass for the product alcohol. Oil derived from a feedstock of an alcohol fermentation process can be chemically converting into the fermentation product extractant.

Abstract: Cytochrome P450 BM-3 from Bacillus megaterium was engineered using a combination of directed evolution and site-directed mutagenesis to hydroxylate linear alkanes regio- and enantioselectively using atmospheric dioxygen as an oxidant. Mutant 9-10A-A328V hydroxylates octane primarily at the 2-position to form S-2-octanol (40% ee). Another mutant, 1-12G, hydroxylates alkanes larger than hexane primarily at the 2-position, but forms R-2-alcohols (40-55% ee). These biocatalysts are highly active for alkane substrates and support thousands of product turnovers. These regio- and enantio-selectivities are retained in whole-cell biotransformations with E. coli, where the engineered P450s can be expressed at high levels and the expensive cofactor is supplied endogenously.

Abstract: A method for fermenting coffee beans is disclosed. Bacteria secreting chimeric proteins comprising endo polygalacturane A (PGAA) and pectin methyl esterase 1 (PME1), which target the pectin coating for hydrolysis, are described. The net result of this targeted hydrolysis of the inner pectin coating can be the production of coffee beans with unique and unexpected flavor characteristics. Desirable flavors can be created or enhanced without any of the adverse taste qualities associated with artificial flavors. For lower grade coffee beans, this process serves to reduce or eliminate undesirable flavors.
