Abstract: Lignocellulosic biomass hydrolysate fermentation broth may be processed to produce a high solids syrup having relatively low viscosity that has a high energy content and may be burned in a fermentation production process. The high solids syrup was achieved through liquid/solid separation of broth or depleted broth producing a thin stillage with low suspended solids allowing evaporation to high solids while maintaining low viscosity.
Abstract: Methods to convert lignocellulosic biomass to fermentable sugars with enzymes that degrade the lignocellulosic material are provided, as well as novel combinations of enzymes, including those that provide a synergistic release of sugars from plant biomass.

Abstract: Networks of single-walled carbon nanotubes (SWCNTs) decorated with Au-coated Pd (Au/Pd) nanocubes are employed as electrochemical biosensors that exhibit excellent sensitivity (2.6 mA mM?1 cm?2) and a low estimated detection limit (2.3 nM) at a signal-to-noise ratio of 3 (S/N=3) in the amperometric sensing of hydrogen peroxide. Biofunctionalization of the Au/Pd nanocube-SWCNT biosensor is demonstrated with the selective immobilization of fluorescently labeled streptavidin on the nanocube surfaces via thiol linking. Similarly, glucose oxidase (GOx) is linked to the surface of the nanocubes for amperometric glucose sensing. The exhibited glucose detection limit of 1.3_M (S/N=3) and linear range spanning from 10 ?M to 50 mM substantially surpass other CNT-based biosensors.
