Abstract: The present invention relates to systems, compositions and methods for the conversion of lignocellulosic material to recalcitrant cellulose and hydrolyzed sugars and products produced therefrom (e.g., biofuel, nano-fibrillated cellulose). In particular, the invention provides novel fractionation processes configured to integrate production of hydrolyzed sugars (e.g., for biofuel production) and recalcitrant cellulose (e.g., for nano-fibrillated cellulose production) from lignocellulosic material and methods of using the same (e.g., in the production of biofuel and nano-fibrillated cellulose). The invention is also directed to nanocellulose with morphologies of having a less entangled and slightly branched fibril network, and having the same thermal stability as of that of the initial lignocellulose feedstock.

Keywords: nanocellulose; lignocellulosic; recalcitrant cellulose; hydrolyzed sugars; biofuel; nano-fibrillated cellulose; conversion (bioconversion); fractionation process; biomass; sustainable; single process
