In another aspect, the invention comprises a computer-implemented method comprising: (a) electronically receiving data regarding prices of one or more exchange-traded futures contracts; (b) selecting, based on said received data, one or more of said futures contracts for inclusion in a commodity index; and (c) electronically calculating excess return for each of said commodities by accounting for foreign exchange rates.

Disclosed is a culture system for the production of algae biomass to obtain lipid, protein and carbohydrate. By integrating heterotrophic processes with a phototrophic process in parallel, this system provides year around production in colder climates. By integrating heterotrophic processes with a phototrophic process in series, this system creates a two-stage, separated mixed-trophic algal process that uses organic carbon and nutrients for the production of seed in the heterotrophic process, followed by release of cultured seed in large-scale phototrophic culture for cell biomass accumulation. Organic carbon source including waste materials can be used to feed the heterotrophic process. The production capacity ratio between the heterotrophic and the phototrophic processes can be adjusted according to season and according to the availability of related resources. The systems are used for producing and harvesting an algal biofuel feedstock as well as other potential high-value products. The sequence and approach enhances utilization of carbon and nutrient waste-streams, provides an effective method for controlling contamination, adds flexibility in regard to production and type of available products, and supplies greater economic viability due to maximized use of available growth surface areas.

The invention provides novel methods for optimizing the design of a fatty acid alkyl ester-containing biofuel (e.g. a biodiesel, a biodiesel blend, or a jet biofuel) and for identifying a fatty acid alkyl ester-containing biofuel's feedstock.

The invention provides methods for decreasing lignin content and for increasing the level of fermentable carbohydrates in plants by down-regulation of the NST transcription factor. Nucleic acid constructs for down-regulation of NST are described. Transgenic plants are provided that comprise reduced lignin content. Plants described herein may be used, for example, as improved biofuel feedstock and as highly digestible forage crops. Methods for processing plant tissue and for producing ethanol by utilizing such plants are also provided.

According to this invention, plants of the genus Triodia are harvested for use as a renewable energy source or as a means of carbon sequestration. Triodia is a hummock-forming grass endemic to Australia, commonly known as spinifex. It is an abundant perennial plant which grows in semi-arid and arid regions. The novel use of Triodia as a biofuel feedstock has many advantages over the prior art. Being perennial, there is no need to plant and fertilise crops. The plants can be continuously harvested without damaging the soil. Triodia grows well with even small amounts of natural rainfall.

The invention provides modified oleosins, including at least one artificially introduced cysteine, and methods and compositions for producing the modified oleosins. Also provided are polynucleotides encoding the modified oleosins, constructs and host cells comprising the polynucleotides, methods for producing oil bodies comprising the modified oleosins, in vivo and in vitro, and methods for producing oil in host cells and plants. The invention also provides methods for increasing the rate of CO₂ assimilation in photosynthetic cells and plants, and involves reducing or preventing lipid recycling, and/or expressing modified oleosins with artificially introduced cysteine residues in the photosynthetic cells and plants. Also provided are methods for increasing oil production in plants, via expression of modified oleosins in the non-photosynthetic tissues/organs of plants. The method also optionally includes the step of extrating the oil from the non-photosynthetic tissues/organs of the plant, or processing the oil rich non-photosynthetic tissues/organs into animal or biofuel feedstocks.

A process for preparing aromatic compounds from a liquid biofuel feedstock by introducing the feedstock into a hydroreforming stage in the presence of hydrogen and a hydroreforming catalyst that contains a transition metal of a group 3 to 12 element and an activated carbon, silicon carbide, silica, transition alumina, alumina-silica, zirconium oxide, cerium oxide, titanium oxide, or an aluminate of a transition metal substrate, to obtain a liquid effluent that contains an aqueous phase and an organic phase, a stage for hydrotreatment of the organic phase, a hydrocracking stage, recycling a fraction that boils higher than 160° C. in said hydrocracking stage, a separation into a fraction containing naphtha and a fraction that boils higher than 160° C., a stage for catalytic reforming of the fraction containing naphtha to obtain hydrogen and a reformate that contains aromatic compounds and a stage for separation of the aromatic compounds of the reformate.

A method of reducing maintenance costs and carbon footprints near/on roadways, airports, public and private right of ways, military areas, unused construction areas, government and subsidy lands by utilizing these areas for the growth of biofuel feedstock materials. Crops used for production of biofuels could be grown in or around these areas and processed into biofuels in the same general area. This process would produce lower exhaust emissions compared with fossil fuels, decrease cost of maintenance of roadways and public right of ways, decrease the United States dependence on foreign oil and decrease transportation costs of fuels to customers, alleviate pest pressures, reduce storm water runoff and help to control fire danger. This process includes, but is not limited to sustainable tillage growth of common biofuels feedstock crops including: canola, rape, mustard, camelina, sunflower; harvesting said crops and turning the biomass yield into biofuels.
