Abstract
The process represents a sustainable and selective approach of biomass hemicellulose fraction transformation into pivot chemicals, such as xylose and furfural, solely mediated by the acidic [bmim][HSO4] ionic liquid.

Abstract
The objective of this paper is to report liquefaction of pretreated and sterilized sugarcane bagasse for enhancing endoglucanase production through submerged fermentation by Aspergillus niger. After initial solid state fermentation of steam pretreated bagasse solids by A. niger, fed-batch addition of the substrate to cellulase in buffer over a 12h period, followed by 36h reaction, resulted in a liquid slurry with a viscosity of 0.30±0.07Pas at 30% (w/v) solids. Addition of A. niger for submerged fermentation of sterile liquefied bagasse at 23% w/v solids resulted in an enzyme titer of 2.5IUmL(-1) or about 15× higher productivity than solid-state fermentation of non-liquefied bagasse (final activity of 0.17IUmL(-1)). Bagasse not treated by initial solid-state fermentation but liquefied with enzyme gave 2IUmL(-1). These results show the utility of liquefied bagasse as a culture medium for enzyme production in submerged fermentations.

Abstract
Instant catapult steam explosion (ICSE) offers enormous physical force on lignocellulosic biomass due to its extremely short depressure duration. In this article, the response surface methodology was applied to optimize the effect of working parameters including pressure, maintaining time and mass loading on the crystallinity index and glucose yield of the pretreated corn stover. It was found that the pressure was of essential importance, which determined the physical force that led to the morphological changes without significant chemical reactions, and on the other hand the maintaining time mainly contributed to the thermo-chemical reactions. Furthermore, the pretreated biomass was assessed by scanning electron microscope, X-ray diffraction and Fourier transform infrared spectra to understand mechanisms underlying the ICSE pretreatment.
