NOVELTY - Production of at least one fatty acid and/or oil from a plant cell suspension culture, comprises: maintaining a cell suspension culture of oil-producing plant cells under conditions such that the cultured cells synthesize and secrete at least one fatty acid and/or oil into the cell suspension culture medium; and extracting the secreted at least one fatty acid and/or oil from the cell suspension culture medium.    USE - The process is useful: to produce fatty acid and/or oil, which is converted to a biofuel, or is optionally further purified and/or used in a downstream process by incorporation into a food product, cosmetic, or lubricant; to produce biological product (fatty acid and/or oil, a proteinaceous product (including recombinantly-encoded proteinaceous products) and a metabolite, such as ethanol. The two-culture system or the carbon dioxide capture system is useful to capture carbon dioxide. The extract or the biofuel is useful as a supplementary source of fuel for a carbon dioxide-producing process. The vegetable oils produced are used to manufacture bio-fuels. The cell suspension culture is useful to produce the fatty acid and/or oil, where the fatty acid and/or oil is secreted into the cell suspension culture medium (all claimed).    ADVANTAGE - The process provides reaction yield of greater than 50%, preferably 93% of fatty acid and/or oil. The cells isolated from a plant from the genus Triticum and propagated in culture produces a very similar profile of fatty acid and oil compounds compared to the profile of fatty acid and oil compounds found in a whole Triticum plant. The process prevents, reduces or reverses the addition of glycerine to the fatty acids and so reduce or remove the need for production of waste during the fatty acid extraction. The process provides efficient conversion of fatty acids and/or oils to biofuel (93.4%) by using much lower amounts of methanol.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for:    (1) the cell suspension culture of oil-producing plant cells comprising an inhibitor of fatty acid glyceration;    (2) a buffered plant cell suspension culture medium having a pH of less than 7, 6.5, 6 or 5.5, preferably 4.5-5.5 for culturing a plant cell suspension culture by the method;    (3) an extract of the fatty acid and/or oil obtainable by the method or a product comprising the extract comprising food product, cosmetic or lubricant;    (4) a biofuel obtainable by the method;    (5) production of a biological product, comprising maintaining a first cell suspension culture of photosynthetic plant cells under conditions that allow the cultured cells to photosynthesize and thus generate and release sugars, typically mono- and/or di-saccharides (e.g. glucose, sucrose, and/or fructose) into the surrounding culture medium, maintaining a second cell culture in the presence of the sugar generated by the first cell suspension culture to allow growth of the second culture and the production of a biological product;    (6) a two-culture system for producing the biological product, comprising the first plant cell suspension culture and the second cell culture;    (7) a carbon dioxide capture system comprising at least the first plant cell suspension culture, and optionally also the second cell culture;    (8) a carbon dioxide-producing power generating facility comprising the two-culture system or the carbon dioxide capture system;    (9) a carbon dioxide-producing biofuel (bioethanol or other alcohol) generating facility comprising the two-culture system or the carbon dioxide capture system;    (10) a method for producing biofuels from at least one fatty acid and/or mono-, di- and/or tri-glycerides comprising reacting a first volume of the fatty acid and/or mono-, di- and/or tri-glycerides with a second volume of a reactant comprising alcohol, alkane or alkene, in the presence of a base catalyst, to form the biofuel, where the ratio of first volume to second volume is greater than 1:6, preferably 1:5-1:1; and    (11) a method for producing vegetable oils from tissue culture cell lines derived from plants.
