Second generation of biofuels

See:

Article reads: The second generation of biofuels converts biomass or cellulosic material from grass, corn cobs and stover, trees or waste into ethanol. Researchers at SDSU have had a switchgrass breeding program for this type of bioenergy since the 1980s. A current five-year project at the North Central Sun Grant Center at SDSU has researchers working to optimize another native grass, prairie cordgrass, for ethanol production. This project is also developing biomass fractionation pretreatments, techniques to reuse enzymes, thermotolerant yeast, and a new generation of high solids bioreactors. Additionally, a Department of Defense project at SDSU is working to produce jet fuels from biomass such as prairie cordgrass.
