The present invention provides an improved process of treating crop kernels to provide a starch product of high quality suitable for conversion of starch into mono- and oligosaccharides, ethanol, sweeteners. The present invention also provides polypeptides having GH10 xylanase activity, polypeptides having GH62 arabinofuranosidase activity and the uses thereof.

A process for production of biofuels from algae can include cultivating an oil-producing algae by promoting sequential photoautotrophic and heterotrophic growth. The method can further include producing oil by heterotrophic growth of algae wherein the heterotrophic algae growth is achieved by introducing a sugar feed to the oil-producing algae. An algal oil can be extracted from the oil-producing algae, and can be converted to form biodiesel.

The present invention provides marine lysophosphatidylcholine compositions for use in pharmaceuticals, nutraceuticals and functional foods, as well as methods for making marine lysophosphatidylcholine compositions.

Process for the production of lipids from biomass including at least one polysaccharide comprising: —subjecting said biomass to hydrolysis to obtain a mixture comprising a first solid phase and a first aqueous phase; —preparing an inoculum comprising at least one oleaginous microorganism in a first fermentation device to obtain a first fermentation broth; —feeding said first aqueous phase and said first fermentation broth to a second fermentation device to obtain a second fermentation broth; —subjecting at least a portion of said second fermentation broth to microfiltration to obtain a first retentate and a first permeate; —feeding said first retentate to said second fermentation device; —subjecting said first permeate to a purification treatment to obtain a second permeate and a second retentate; —feeding said second retentate to said second fermentation device; —at the end of said fermentation, subjecting said second fermentation broth to separation to obtain an aqueous suspension of oleaginous cellular biomass comprising lipids and a second aqueous phase. The lipids thus obtained can advantageously be used in the production of biofuels.

Provided herein are methods of recovering oil from microorganisms. The methods are useful, for example, in obtaining nutritional oils and/or lipid biofuels. The methods of recovering oil described herein include contacting a population of microorganisms with one or more enzymes under conditions that cause disruption of the microorganisms, concentrating the disrupted microorganisms, and extracting lipids from the disrupted microorganisms at high temperature in the presence of a salt and in the absence of solvent.

A process for extraction of crude oil from distillers dried grain solubles and/or distillers dried grains using a solvent extraction process and producing corn distillers meal that may be used as an animal feed supplement is disclosed. The corn distillers meal may be used as a crude protein supplement for use in a livestock feed diet, poultry feed diet, aquatic feed diet or the like. The solvent extracted crude oil may be suitable for other processes, including oleochemical processing for personal care and home care products, biodiesel production, and/or renewable diesel production from hydro-treating the extracted oil to make green diesel fuel.

The present invention is directed to a method of enhanced production of lipids by limitation of at least two limiting nutrient sources during the fermentation of the lipids producing cells.

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.
