Butanol Touted as Gasoline of the Future
Scientists reported a discovery that could speed an emerging effort to replace ethanol in gasoline with a substantially better fuel additive called butanol, which some experts regard as “the gasoline of the future.” Their report on this discovery, which holds potential to reduce the costs of converting ethanol factories to production of butanol, came at the 245th National Meeting & Exposition of the American Chemical Society.
Duncan Wass explains that ethanol has become a leading biofuel — millions of gallons added to gasoline around the country each year — despite several disadvantages. Ethanol, for instance, has a lower energy content per gallon than gasoline, which can reduce fuel mileage. Ethanol also has a corrosive effect on car engines and can’t easily be used in amounts higher than 10-15 percent.

Genetically Engineered E. coli Produces Biofuel Replacement For Petroleum
Escherichia coli has been genetically engineered by scientists at the University of California, Los Angeles to produce butanol: an alcohol like ethanol, that can directly replace our petroleum needs (unlike ethanol). Butanol is chemically better than ethanol as a biofuel for numerous reasons:
- Butanol has a higher octane number than ethanol (butanol contains more energy)
- Butanol is less corrosive than ethanol (butanol can be put in existing engines and infrastructure)
- Butanol is less soluble in water than ethanol (makes ethanol more difficult to separate from contaminated water supplies)
Previously butanol has been produced through two pathways: ABE (acetone, butanol, ethanol) fermentation or petrochemical cracking. ABE fermentation is very inefficient and petrochemical cracking requires non -renewable crude oil. Therefore the production of butanol needed to be refined.
The refined, efficient process of butanol production involves genetically engineered E. coli. Some of E. coli’s keto acid metabolites have been diverted from amino acid synthesis to butanol production through the insertion of two non-native genes (genes from other species) and deletion of other certain genes. The inserted genes code for an enzyme that converts some of the organism’s keto acids to aldehydes and another enzyme that converts the aldehydes to butanol. The deleted genes increased the amount of keto acids to be converted.
Butanol producing E. coli can be still be improved upon further. The organisms need to be genetically engineered to produce butanol at a faster rate and their tolerance of butanol in the substrate must be raised, if butanol is to be commercially competitive with ethanol.

butanol replied to your post: Pretty much thrilleddddd
WHY i dared to ask
As silly as it sounds, I feel like this might jinx it so I’m knocking on wood but pretty much everything in my life is going well right now! School this semester is starting out well and I’m not struggling too much as a RA and I’m socializing and making new friends and eating decently and spending more of my time with people who legitimately want to be around me and show me that they do. Before this, I was spending way too much time around people who didn’t enjoy my company as much as I enjoyed theirs and it’s so so nice to finally feel desired/appreciated for a change.
