Bioconversion of pentose sugars to value added chemicals and fuels: Recent trends, challenges and possibilities

Edgard Gnansounou, Vinod Kumar

Most of the crop plants contain about 30% of hemicelluloses comprising D-xylose and D-arabinose. One of the major limitation for the use of pentose sugars is that high purity grade D-xylose and D-arabinose are yet to be produced as commodity chemicals. Res ...

Complex event recognition through wearable sensors

Jean-Eudes Marie Ranvier

Complex events are instrumental in understanding advanced behaviours and properties of a system. They can represent more meaningful events as compared to simple events. In this thesis we propose to use wearable sensor signals to detect complex events. Thes ...

A mild biomass pretreatment using gamma-valerolactone for concentrated sugar production

Jeremy Luterbacher, Ydna Marie Questell-Santiago, Li Shuai

Here we report that gamma-valerolactone (GVL), a biomass-derived solvent, can be used to facilitate the mild pretreatment of lignocellulosic biomass. An 80% GVL, 20% water solvent system was used to pretreat hardwood at the mild temperature of 120 degrees ...
