NOVELTY - Producing biofuels using photosynthetic organisms, comprises: identifying photosynthesis co-factors and their anchors in the organisms; modifying the organism's biosynthesis pathway to increase production of the anchors; accumulating co-factor biomass; and harvesting the anchors from the biomass.    USE - The process is useful: for producing biofuels using photosynthetic organisms; and for producing fuel precursors and intermediate moieties, which are useful in the production of petroleum-based products comprising plastics, synthetics, composites, insecticides, paints, medicine, etc.    ADVANTAGE - The process: utilizes organisms, which are easily engineered to over-produce the desired molecules and export these molecules from the cell to a growth medium, thus simplifies the harvesting of the target molecules; provides biofuels with or without fermentation or distillation, thus making it more flexible from an energy use and efficiency compared to prior process; provides moieties which does not undergo further refining before blending with existing fuels or consumed directly; provides natural, cost and energy efficient mechanism to extract the desired biofuel molecules; facilitates an efficient and uncomplicated collection process of desired biofuel molecules from growth media; produces lipids as by-product (30-70 percent) which can be used to produce other fuel sources; efficient synthesis of biofuels, limiting or excluding post separations steps; minimizes the use of resources (time, land and water); provides fuel, which uses a source that avoids competition with other human and environmental activities (e.g. food and feed production); provides fuel, which permits and promotes efficient combustion, and does not require significant changes in the infrastructure for producing, distributing or utilizing the fuel; and significantly reduces greenhouse gas emissions on a life cycle basis.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for:    (1) extracting anchors of co-factor molecules from a biomass of photosynthetic organisms, comprising increasing the production of the co-factor molecules, contacting the co-factor molecules with an enzyme to cleave the anchors from the cofactor molecules and isolating the anchors from the biomass; and    (2) a biofuel comprising moieties of 5-30 carbons in length, the moieties are generated from interruptions of biosynthetic pathways of photosynthetic bacteria.
