Bacteria<BR></STRONG>Butanol may be used as a fuel in an internal combustion
engine. Because its longer hydrocarbon chain causes it to be fairly non-polar,
it is more similar to gasoline than it is to ethanol. Butanol has been
demonstrated to work in vehicles designed for use with gasoline without
modification. University of California, Berkeley, chemists have engineered
bacteria to churn out a gasoline-like biofuel (butanol) at about 10 times the
rate of competing microbes, a breakthrough that could soon provide an affordable
transportation fuel. The potential feedstocks are the same as for ethanol:
energy crops such as sugar beets, sugar cane, corn grain, wheat and cassava,
prospective non-food energy crops such as switchgrass and even guayule in North
America, as well as agricultural byproducts such as straw and corn
stalks.<BR></FONT></FONT><A href="http://www.enn.com/business/article/42416"
