Methods and compositions for the recombinant biosynthesis of
The present disclosure identifies methods and compositions for modifying photoautotrophic organisms as hosts, such that the organisms efficiently convert carbon dioxide and light into n-alkanes, and in particular the use of such organisms for the commercial production of n-alkanes and related molecules.
1. A fuel composition comprising a mixture of alkanes and alkanol, wherein the mixture comprises pentadecane, hexadecane, heptadecane, and alkanol, wherein heptadecane and pentadecane are the predominant alkanes in the mixture, and wherein at least a portion of the carbon used as raw material of the alkanes and alkanol is inorganic carbon.
2. The fuel composition of claim 1 , wherein the fuel composition further comprises nonadecene.
3. The fuel composition of claim 1 , wherein the fuel composition further comprises tridecane.
4. The fuel composition of claim 1 , wherein the fuel composition further comprises tetradecane.
5. The fuel composition of claim 1 , wherein the fuel composition is a low-sulfur fuel composition.
6. The fuel composition of claim 1 , wherein the fuel composition is a carbon-neutral fuel composition.
7. The fuel composition of claim 1 , wherein the fuel composition has a higher δ p than a comparable fuel composition made from fixed atmospheric carbon or plant-derived biomass.
8. The fuel composition of claim 1 , wherein the fuel composition further comprises diesel.
9. The fuel composition of claim 1 , wherein the alkanol is octedecan-1-ol.
