NOVELTY - Oil from fermentation product is recovered which involves: (a) fermenting an oil-containing biomass feedstock to produce a fermentation product comprising an oil; (b) introducing a gas into the fermentation product to form an oil-poor component and an oil-rich component; and (c) separating the oil-rich component from the oil-poor component to produce a recovered oil-rich product.    USE - The methods and system are useful for recovering oil from e.g. fermentation product, whole stillage, and biomass (all claimed).    ADVANTAGE - Processes and systems for recovering oil from fermentation product are provided that optimize oil recovery during fermentation. The processes and systems introduce a gas into the fermentation product in order to cause the oil within the fermentation product to separate, thus facilitating its subsequent recovery. The processes and systems can maximize the amount of oil that can be recovered during fermentation. The process can also improve grain oil recovery by breaking down and fermenting the fiber in the fat-rich germ portion of the grains. Compared to the prior art, less equipment and energy can be required to separate and recover the oil from the fermentation product. For example, the processes can remove the need for a centrifugation step and other heating or chemical treatments commonly used in prior art processes. Thus, the processes and systems can save on both equipment and energy costs. Further, by drawing the oil off during the fermentation stage, there is less chance of oil loss through other parts of the process.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for:    (1) a method for recovering an oil from whole stillage, which involves: (a) fermenting a whole stillage to produce a fermentation product comprising an oil; (b) introducing a gas into the fermentation product to form an oil-poor component and an oil-rich component; and (c) separating the oil-rich component from the oil-poor component to produce a recovered oil-rich product; and    (2) a system for recovering an oil from biomass, comprising: (a) a fermentation tank configured to ferment an oil-containing biomass feedstock into a fermentation product; (b) a gas injection system in fluid communication with the fermentation tank, where the gas injection system is configured to introduce a gas into the fermentation product, thus separating it into an oil-poor component and oil-rich component; and (c) an oil recovery system in fluid communication with the fermentation tank, where the oil recovery system is configured to recover the oil-rich component.
