TECHNOLOGY FOCUS - BIOTECHNOLOGY - Preferred Method: In cracking the biocrude, the substrate containing the fatty acyl chain is selected from acyl-ACP, free fatty acid, acyl-coenzyme A (CoA), a fatty aldehyde, a hydrocarbon intermediate, such as an aliphatic ketone, a fatty alcohol, such as a short or long chain fatty alcohol, a fatty acid ester, including a wax, a phospholipid, a lipid A, and their combinations. The recombinant microorganism over expresses one or more peptides selected from acyl-CoA synthetase (EC 6.2.1.3, 2.3.1.86), thioesterase (EC 3.1.2.-, 3.1.1.15, 3.1.2.14), acetyl-CoA carboxylase (EC 6.4.1.2, 6.3.4.14), an acyl-carrier protein, pyruvate dehydrogenase (EC 1.2.4.1), aldehyde decarbonylase (EC 4.1.99.5), beta -hydroxydecanoyl thioester dehydrase (EC 4.2.1.60), 3-oxoacyl-(acyl-carrier-protein) synthase I (EC 2.3.1.41), (acyl-carrier-protein) S-malonyltransferase (EC 2.3.1.39), 3-oxoacyl(acyl-carrier protein) reductase (EC 1.1.1.100), 3-oxoacyl-(acyl-carrier-protein) synthase III (EC 2.3.1.180), enoyl-(acyl-carrier-protein) reductase (EC 1.3.1.9), (3R)-hydroxymyristol acyl carrier protein dehydratase (EC 4.2.1.-), lipase (EC 3.1.1.3), malonyl-CoA decarboxylase (EC 4.1.1.9, 4.1.1.41), aspartate 1-decarboxylase (EC 4.1.1.11), pantothenate kinase (EC 2.7.1.33), pyruvate dehydrogenase (EC 1.2.4.1), pyridine nucleotide transhydrogenase (EC 1.6.1.1) and hydrocarbon synthase. The cracking comprises catalytic cracking, and does not include hydrocracking or steam cracking. Moreover, the cracking comprises contacting the biocrude with a catalyst selected from zeolite, aluminum hydrosilicate, treated bentonite clay, fuller's earth, bauxite, amorphous silica-alumina and mixtures or combinations. The catalyst is an amorphous silica-alumina. The cracking converts C19-C31 hydrocarbons in the biocrude to C1-C18 hydrocarbons. It also converts 65-75 wt% of hydrocarbons in the biocrude to lower molecular weight hydrocarbons. Furthermore, the recombinant microorganism over expresses an ester synthase (EC 2.3.1.-). The cracked product includes a C5-C10 fraction having a boiling point of 30-180 degrees C at 1 atm, a C8-C14 fraction having a boiling point of 120-260 degrees C at 1 atm, and a C14-C18 fraction having a boiling point of 230-320 degrees C at 1 atm, where the cracked product is characterized by multiple fractions that are each distillable at a different temperature range. The cracked product includes a gasoline fraction having a distillation range of 20-210 degrees C at 1 atm. The method also comprises refining the cracked product into at least one transportation fuel, mixing the biocrude with petroleum crude prior to cracking, and then cracking the resulting biocrude/petroleum crude mixture. Moreover, the cracked product includes at least 50 wt% C5 and greater hydrocarbons, based on the total hydrocarbon amount in the cracked product. The biocrude includes greater than 90-99 wt% alkene compounds, based on the total weight of the biocrude. The biocrude is produced by the microorganism, preferably the recombinant microorganism. Also, the biocrude is produced by: contacting the recombinant microorganism with a carbon source under conditions sufficient for producing the biocrude, where the recombinant microorganism over expresses a fatty acyl chain containing product forming enzyme. The method further comprises culturing the recombinant microorganism under conditions sufficient to produce hydrocarbons, and separating the hydrocarbons, where culturing and separating is continuous. Also, separating comprises contacting the fermentation media with the organic composition and allowing the hydrocarbon to separate into the organic composition. The recombinant microorganism is selected from Escherichia coli, S. maltophilia, K. radiotolerans, Rhodococcus, Saccharomyces cerevisiae, Aspergillus, Trichoderma, Neurospora, Fusarium or Chrysosporium. Moreover, the cracked product includes a jet fuel fraction having a distillation range of 170-290 degrees C at 1 atm, a diesel fraction having a distillation range of 180-320 degrees C at 1 atm, at least 15 wt% of a gasoline fraction based upon the total weight of the recovered cracked product, and at least 30 wt% of a diesel fraction based upon the total weight of the recovered cracked product. In cracking the hydrocarbon feedstock produced by the microorganism, the hydrocarbon feedstock includes greater than 80wt % C19-C31 compounds. Also, the hydrocarbon feedstock includes C22-C31 hydrocarbons having at least one alkene moiety. In making the biofuel, the biofuel includes the C5-C10 fraction having the boiling point of 30-180 degrees C at 1 atm. Preferred Mixture: In the mixture, the other fuel component is a petroleum-based fuel, where the petroleum-based fuel is gasoline, diesel, jet fuel, or a mixture. EXAMPLE - No suitable example given.
