The news is from scientists at Berkeley Lab. They used advanced computing tools to produce it. It is possible to have jet fuel made from bacteria. It is ecological and does not pollute.
Why are you looking for sustainable aviation fuels made from renewable carbon sources? Because they could reduce carbon dioxide emissions and help mitigate climate change. Isoprenol is a key chemical in a new jet biofuel. It is called 1,4-dimethylcyclooctane (DMCO). Blends are chemicals that combine with other chemicals to create fuel. Researchers have produced isoprenol in various microbial hosts.

genetic engineering
Isoprenol is expected to be produced in microorganisms that use fermentable sugars from plant material as a carbon source. The bacteria Pseudomonas putida (P. putida) could be one of those microorganisms. But it needs engineering to be an optimal option.
By editing the genes and metabolism in this bacteria, isoprenol production can be maximized. This approach allowed researchers to select and prioritize gene editing targets. Thus, they tested a smaller number of engineered strains. They achieved the highest production of isoprenol reported for this bacteria. This is an important step towards a sustainable bioproduction process for jet fuel. This, according to a statement from the US Department of Energy.
The researchers used a combination of computational modeling and strain engineering. Thus they optimized the production of isoprenol in the bacteria. They used multiple approaches based on genomic-scale metabolic models. And they eliminated genes that would lead to higher yields of isoprenol. This allowed them to reduce the number of targets they pursued.

Greater production of bacteria
The research achieved an isoprenol production titer of 3.5 grams per liter, the highest reported for P. putida. This is equivalent to a tenfold improvement of isoprenol in the aforementioned bacteria.
The researchers suggest that further improvements should be made to improve isoprenol yields for industrial applications. Commercial scale production of isoprenol and DMCO still requires further improvements. Jet fuel made from bacteria requires still other bioprocess technologies. But it is progress.
