Abstract: Methods for treating lignocellulosic biomass to produce readily saccharifiable carbohydrate-enriched biomass are provided. In one method, lignocellulosic biomass comprising lignin is treated with aqueous ammonia, then contacted with a gas comprising ozone at a temperature of about 0 °C to about 50 °C. In another method, lignocellulosic biomass comprising lignin is contacted with a gas comprising ozone at a temperature of about 0 °C to about 50 °C, then treated with aqueous ammonia. The readily saccharifiable carbohydrate-enriched biomass may be saccharified with an enzyme consortium to produce fermentable sugars.

Abstract: An alcohol fermentation process and composition that includes production of alcohol esters by esterification of product alcohol in a fermentation medium with a carboxylic acid (e.g., fatty acid) and a catalyst (e.g., lipase) capable of esterifying the product alcohol, such as butanol, with the carboxylic acid to form the alcohol esters. The alcohol esters can be extracted from the fermentation medium, and the product alcohol recovered from the alcohol esters. The carboxylic acid can also serve as an extractant for removal of the alcohol esters from the fermentation medium.

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. The oil can be separated from the feedstock prior to the feedstock being fed to a fermentation vessel, and the separated oil can be chemically converted to a fermentation product extractant, which can then contacted with a fermentation product comprising a product alcohol, whereby the product alcohol is separated from the fermentation product.
