A breakthrough

They made it for the first time, in Finland´s Turku, a synthetic metabolic pathway for producing renewable ​propane.
The pathway is based on a thioesterase specific for butyryl-acyl carrier protein, which allows native fatty acid biosynthesis of the Escherichia coli host to be redirected towards a synthetic alkane pathway. ​Propane biosynthesis is markedly stimulated by the introduction of an electron-donating module, optimizing the balance of ​O2 supply and removal of native aldehyde reductases.
There are the deployment of next-generation renewable biofuels
They can be enhanced by improving their compatibility with the current infrastructure for transportation, storage and utilization. ​
Propane, the bulk component of liquid petroleum gas, is an appealing target as it already has a global market. In addition, it is a gas under standard conditions, but can easily be liquefied.
This allows the fuel to immediately separate from the biocatalytic process after synthesis, yet does not preclude energy-dense storage as a liquid.
