The present invention relates to production of fuels or fuel blendstocks from renewable sources. Various embodiments provide a method of producing a hydrocarbon product by hydrotreating a feedstock including at least one of a renewable triacylglyceride (TAG), renewable free fatty acid (FFA), and renewable fatty acid C1-C5 alkyl ester (C1-C5 FAE) in the presence of a nonsulfided hydrotreating catalyst to produce a first product including hydrocarbons. In some examples, the first product can be subjected to further chemical transformations such as aromatization, cracking, or isomerization to produce a second product including hydrocarbons. In various embodiments, the first or second hydrocarbon product with minimal or substantially no further processing can be suitable as a liquid transportation fuel or fuel blendstock, including fuels such as gasoline, naptha, kerosene, jet fuel, and diesel fuels.

The present invention relates to the isolation, purification, characterization and use of the plant diacylglycerol acyltransferase, DGAT, gene and associated gene products. The invention includes isolated and purified DGAT cDNA (SEQ ID NO: 1) and a plant diacylglycerol acyltransferase gene (SEQ ID NO: 3) and homologues thereof from the Brassicaceae, such as Arabidopsis thaliana. Methods of using the DGAT DNA to regulate seed oil content, the ratio of diacylglycerol / triacylglycerol proportions in the seed oil, fatty acid synthesis, seed oil acyl composition, seed size / weight and carbon flux into other seed components are also included. Methods of producing transgenic plants, plant tissues and plant seeds having genomes including DGAT genes, and the resultant transgenic plants, plant tissues and plant seeds are also included.

Nucleic acid compositions encoding polypeptide products with diglyceride acyltransferase activity, as well as the polypeptide products encoded thereby and methods for producing the same, are provided. The subject polypeptide and nucleic acid compositions find use in a variety of applications, including research, diagnostic, and therapeutic agent screening applications, as well as in treatment therapies and in the production of triacylglycerols.

The production of transgenic plant oils is described by transfecting plant host cells with heterologous transcription inducers. Such inducers are specific for endogenous biosynthetic plant oil genes, such that the inducers induce an overexpression of the plant oil genes. The overexpressed gene product (i.e., for example, diacylglycerol transferase) thereby results in a increased intracellular production of a plant oil (i.e., for example, triacylglycerol). In one embodiment, the transfected plant host cell can be a plant algae species (i.e., for example, Chlamydomonas reinhardtii).

This invention relates to a catalyst compound comprising a combination of a cyclic alkyl amino carbene ligand and a benzylidene both attached to a Group 8 metal, preferably ruthenium atom.This invention also relates to a process to make linear alpha-olefins comprising contacting a feed material and an optional alkene (such as ethylene) with the catalyst described above, wherein the feed material is a triacylglyceride, fatty acid, fatty acid alkyl ester, and / or fatty acid ester, typically derived from seed oil (e.g., biodiesel).

The invention relates to at least one nucleotide sequence, derived from a nucleotide sequence encoding an acyltransferase polypeptide comprising at least one membrane-spanning region, encoding an improved active membrane independent acyltransferase polypeptide in which at least one amino acid residue of the membrane-spanning region has been deleted and / or substituted as compared to the original acyltransferase polypeptide, wherein the encoded active membrane independent acyltransferase polypeptide can produce fatty acid esters and / or fatty acid thioesters such as triacylglycerols, diacylglycerols, monoacylglycerols, phospholipids, glycolipids, waxesters, acylated carbohydrates, acylated amino acids, and lysolipids, e.g. lysophosphospholipid, lysolecithin. Thereby one single acyltransferase can be used for the production of a huge number of products. The invention also relates to means and methods for the production of such an improved active membrane independent acyltransferase and the use of such a membrane independent acyltransferase in industry.
