Processes for grinding corn, ground corn products, and processes for making ethanol from the ground corn products. In some examples, a process for making ethanol can include introducing a plurality of corn pieces into a mill. The process can also include milling the corn pieces in the mill to produce a ground corn product. Greater than 25 wt % of the ground corn product can have a particle size of greater than 105 m, as measured according to AOAC 965.22-1966. Greater than 80 wt % of the ground corn product can have a particle size of 425 m or less, as measured according to AOAC 965.22-1966. The process can also include processing the ground corn product to produce a fermentation mash that can include ethanol and separating at least a portion of the ethanol from the fermentation mash to produce a stillage.

Disclosed are techniques and systems for producing microbials having anaplerotic oils that are rich in odd-chain fatty acids, and other beneficial components, at higher concentrations than those present in other natural dietary sources of OCFA, at lower cost, and higher production yield. Such compositions can comprise pentadecanoic and heptadecanoic fatty acids. The techniques described herein include methods for producing and deriving such compositions rich in odd-chain fatty acids from microbials, including microalgae and yeasts/fungi.

The present disclosure is related to refining one or more grain oil composition streams (e.g., distillers corn oil or syrup) in a biorefinery to provide one or more refined grain oil products, where each grain oil product has targeted amounts of a free fatty acid component and the fatty acid alkyl ester component.

The present invention relates to methods of synthesizing long-chain polyunsaturated fatty acids, especially eicosapentaenoic acid, docosapentaenoic acid and docosahexaenoic acid, in recombinant cells such as yeast or plant cells. Also provided are recombinant cells or plants which produce long-chain polyunsaturated fatty acids. Furthermore, the present invention relates to a group of new enzymes which possess desaturase or elongase activity that can be used in methods of synthesizing long-chain polyunsaturated fatty acids.

A method of recovering one or more insoluble oils from a liquid source using one or more membrane or membrane contactors, comprising the steps of: pumping the liquid source comprising the one or more oils to the membranes or membrane contactors, contacting the liquid source with a first surface of the membrane or membrane contactors, coalescing the one or more oils within the liquid source onto the first surface of the membrane contactors, pumping one or more recovery fluids through the membrane or membrane contactors in contact with the second surface of the membrane or membrane contactors, and removing a first stream of oil coalesced from the second surface of the membranes or membrane contactors.

The present invention relates to a method for simultaneously recovering in aqueous medium, from a lipid and protein containing biomass, of a lipid fraction and a protein fraction, wherein the method comprises an extraction step to extract the lipid and protein fraction from the biomass, characterised in that the refining step consists of contacting the biomass with a solution of at least one organic acid in water having a pH of between 1 and 6, wherein the concentration of the organic acid is at least 0.1 M, and in that the method further comprises subjecting the thus treated biomass to a phase separation and recovering a first lipid phase containing at least 65% with respect to the total weight of the lipids contained in the biomass and a second phase containing one or more precipitated proteins.
