  • Method for Producing Butanol Using Extractive Fermentation
    Publication number: 20170057894
    Abstract: The invention relates to a method for producing butanol through microbial fermentation, in which the butanol product is removed by extraction into a water immiscible organic extractant during the fermentation. The invention also relates to a method for producing butanol through microbial fermentation, in which the butanol product is removed during the fermentation by extraction into a water-immiscible extractant composition. The invention further relates to compositions comprising a solution of butanol in a water immiscible organic extractant composition.

  • METHODS FOR DETOXIFYING A LIGNOCELLULOSIC HYDROLYSATE
    Publication number: 20160002359
    Abstract: The present disclosure relates to methods for detoxifying a hydrolysate obtained from a lignocellulosic biomass and methods of producing ethanol from the detoxified hydrolysate. The present methods provide detoxified hydrolysates in which the quantity of compounds that are deleterious to fermenting microorganisms are substantially reduced relative to the starting hydrolysate and in which the amount of fermentable sugars loss is minimal.
