NEW ORLEANS (UPI) -- Scientists in Louisiana say they've foundbacteria that can use recycled paper or any cellulose to producebutanol, a biofuel substitute for gasoline.
The new bacterium, dubbed "TU-103," is the first bacterial strain fromnature that can produce butanol directly from cellulose, a TulaneUniversity release said Thursday.
"Cellulose is found in all green plants, and is the most abundantorganic material on earth, and converting it into butanol is the dreamof many," said Tulane researcher Harshad Velankar.
"In the United States alone, at least 323 million tons of cellulosicmaterials that could be used to produce butanol are thrown out eachyear," he said.
As a biofuel, butanol has advantages over ethanol, the researcherssaid, because it can fuel existing motor vehicles without any enginemodifications and can be transported through existing fuel pipelines.
It is also less corrosive and can produce more energy than ethanol,they said.
"In addition to possible savings on the price per gallon, as a fuel,bio-butanol produced from cellulose would dramatically reduce carbondioxide and smog emissions in comparison to gasoline, and have apositive impact on landfill waste," research leader David Mullin said.
