Aircraft are indispensable in the modern age for transporting people, delivering goods, and performing military operations, but the petroleum-based fuels that power them are in short supply. Scientists have now discovered a way to generate an alternative jet fuel by harvesting an unusual carbon mole
cule produced by the metabolic process of bacteria that are commonly found in soil. The research, by scientists at the“In chemistry, everything that requires energy to make will release energy when it’s broken,” says lead author Pablo Cruz-Morales, a microbiologist at DTU Biosustain, part of the Technical University of Denmark. When petroleum jet fuel is ignited, it releases a massive amount of energy.
Keasling wanted to recreate a molecule called Jawsamycin, which is named after the movie “Jaws” because of its bite-like indentations. It is generated by the common bacteria streptomyces, an organism that Cruz-Morales had worked with in the past. These twists, which give the molecules their explosive properties, are the incorporation of cyclopropane rings – rings of three carbon atoms arranged in a triangular shape. “If you have bonds that are at a normal angle, an open chain of carbons, the carbons can be flexible and they get comfortable,” explains Cruz-Morales. “Let’s say you make them into a ring of six carbons – they can still move and dance a little bit.
