Molecular simulations reveal the effectiveness of THF in disentangling lignin from lignocellulosic feedstocks [Registered]

In the production of cellulosic biofuels breaking down lignocellulosic feedstocks into C5 and C6 sugars is a major challenge. In a leap forward that could be a game-changer for understanding how plant biomass can be more efficiently broken down, researchers from the University of California (UC), Riverside, Oak Ridge National Laboratory and the University of Central Florida have created a chemical roadmap to disentangle the complex polymer lignin from cellulose and hemicellulose.

Genetic mechanisms regulating the production of hydrolytic enzymes by Trichoderma species elicited [Full subscriber]

In the production of cellulosic biofuels, enzymatic hydrolysis of cellulosic feedstock to produce sugars that will be subsequently fermented is central to the process. Researchers at the University of Campinas (UNICAMP) in São Paulo State, Brazil, partnering with colleagues from the National Bioethanol Science & Technology Laboratory (CTBE) have elicited the genetic mechanisms that regulate the control and production of hydrolytic enzymes by, Trichoderma spp.
