Engineered yeast converts toxin aldehydes from hydrolysed lignocellulosic feedstock into alcohol [Full subscriber]

In the production of cellulosic biofuels, breaking down lignocellulosic feedstock to produce fermentable sugars releases numerous by-products that are toxic to yeast most commonly used to produce biofuels. Researchers at the Massachusetts Institute of Technology have engineered yeast to convert toxic cellulosic by-product aldehydes into alcohols.

Efficient and sustainable cellulosic biofuels production via novel laser technique [Full subscriber]

Production of cellulosic biofuels is a complex process requiring separation of cellulose, hemicellulose and lignin from lignonocellulosic feedstocks and then hydrolysing the former two to produce sugars which are then fermented into alcohol. Researchers from Japan have developed a new laser technique for breaking up cellulose with ease to facilitate cellulosic biofuels production.

Customising engineered microbes to improve the economics of cellulosic biofuels production [Registered]

Scientists at the US Department of Energy’s Oak Ridge National Laboratory (ORNL) have demonstrated a method to insert genes into a variety of microorganisms that previously would not accept foreign DNA, with the goal of creating custom microbes to break down lignocellulosic feedstocks into cellulosic sugars and subsequently ferment them. Dubbed “consolidated bioprocessing” (CBP), this approach improves the economics of biofuels production.

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.
