Researchers at US Department of Energy’s Berkeley Lab have transformed lignin into a precursor for a useful chemical with a wide range of potential applications.
Researchers at the Kanazawa University, Japan have developed a novel carboxylate-type liquid zwitterion as a solvent of biomass, which could dissolve cellulose with very low toxicity to microorganisms (with fragile and very vulnerable cell membranes) that play essential roles in the fermentation necessary for producing ethanol.
New organometallic polymer that switches between liquid and solid states when exposed to light or heat [Registered]
Japanese researchers have developed a metal-containing compound which transforms into a solid when exposed to light and returns to liquid form when heated. This substance could potentially be used for photolithography technology, such as fabricating printed circuits, among other applications.
The process utilizes a combination of ionic liquid pretreatment, enzymatic saccharification, and yeast fermentation for the production of concentrated fermentable sugars that result in high-titer cellulosic ethanol. “High gravity” means high biomass loading – the higher the biomass loading, the lower the costs for converting it to fuels.
