Ethanol and butanol are biofuels, which are produced by using plant feedstocks and microorganisms. An industrial polymer called 1,3-propanediol was made from corn and is a near classical industrial biotechnology process. For production of ethanol, Zymomonas mobilis is used and it can turn corn into ethanol at high rate. DuPont is into biofuel research and projects to reduce process expenses because unless they are cheap than petroleum, the biofuels cannot succeed in the market.
