The present invention relates to using high oil corn to make a biochemical such as ethanol. More particularly, the invention relates to methods of making a biochemical using relatively low temperature saccharification followed by fermentation or simultaneous saccharification and fermentation of high oil corn.

Corn blends that include high oil corn and methods of making one or more biochemicals using high oil corn or corn blends that include high oil corn

Methods, compositions, and systems for propagation and fermentation, particularly large scale operations for production of ethanol and dried distiller's grain are provided. Addition ofto propagation and/or fermentation decreases lactic acid bacterial contamination.

Systems, compositions, and methods of fermentation with

Genetically modified microorganisms useful in fermentation and methods of using such microorganisms are provided. Such microorganisms contain a [GAR+] prion or are modified to contain a [GAR+] prion. Exemplary microorganisms include yeast such as. The microorganisms can be further modified to convert xylose and/or arabinose. Methods of fermentation using such microorganisms exhibit improved fermentation efficiency and improved microorganism viability.

Fermentation efficiency using yeast containing prions

The present invention relates to methods and systems of pitching yeast to fermentation reactors. More particularly, the present invention involves pitching yeast from one fermentation tank to at least one additional fermentation tank. Advantageously, yeast can be continuously pitched from fermentor to fermentor for as long as practically desirable.

Methods of pitching yeast for fermentation, and related methods of fermentation and systems

Methods, compositions, and systems for propagation and fermentation, particularly large scale operations for production of ethanol and dried distiller's grain are provided. Addition of urease and urea to propagation and/or fermentation improves yeast health, fermentation efficiency, and quality and quantity of DDG. Urease can be in reagent form or can be endogenous to the natural feedstock.

Methods of improved yeast health and fermentation with urease

Methods to prepare vegetable oil compositions having an elevated ethyl ester content are provided.

Use of an esterase to enhance ethyl ester content in fermentation media

Provided are methods and systems of obtaining oil from a stillage composition.

Methods and systems for obtaining oil from a stillage composition

Disclosed are methods and systems for propagating microorganisms such as yeast using a carbon source that includes glycerol and a nutrient source that includes a stillage component.

Method and system for propagating a microorganism

A pool cover anchor system, for use on deck boards surrounding the pool, includes first and second anchor parts. The first anchor part includes: a first portion having an opening; a second portion that extends away from the first portion; and an anchor member that extends away from the first portion for a hook of the pool cover to be mounted thereto. The second anchor part includes: a first portion pivotally received in the opening in the first anchor part; and a second portion that extends away from the first portion of the second anchor part. The opening in the first anchor part is positioned a distance away from the second portion of the first anchor part for each of the second portion of the first anchor part and the second, portion of the second anchor part to respectively bear against two different deck boards simultaneously, and distribute loads therebetween.

Systems and methods for improving ethanol yield are provided. A feedstock is ground suitably fine for use in fermentation. The feedstock may include corn or any other suitable material. In some cases, the feedstock undergoes a fractionation prior to grinding. The ground feedstock may be slurried with water and enzymes to facilitate conversion of the starch in the feedstock to sugars. The slurry may be about 35% solids. After being slurried, an ethanologen may be added. Additionally, the pH of the slurry may be adjusted to between 4.2 and 5.2 to facilitate the priming A primer is added to the slurry. The primer may include any weak acid, and in some embodiments includes acetic acid. Acetic acid, when used as a primer, may be added at a concentration of between 1200 and 3600 parts per million. The slurry is fermented to produce improved yields of ethanol.

Systems and methods for improving ethanol yield

Assessing quality of feedstock is provided and may be useful for determining quality of feed (such as corn kernels). The assessment determines endogenous enzyme activity within the feedstock, which correlates with total ethanol yields in raw starch hydrolysis (non-cooked) systems. In some embodiments, a sample containing flour (ground feedstock) is provided. In some cases, flour is diluted in water and buffered with a phosphate buffered solution. The buffered flour solution is contacted with a molecule, or fluorescent dye, such as fluorescein diacetate and/or difluorofluorescein that is altered by enzymatic (esterase) activity in a detectable fashion. Enzyme activity may be facilitated using an incubator. The detectible alteration may be measured using a fluorometer. In some embodiments, two incubations and fluorescence measurements can be performed. By subtracting the difference between the measured fluorescence, a fluorescence index may be found, which correlates with the endogenous enzyme activity in the feedstock sample.

Systems and methods for feedstock quality assessment

A method of producing bioproducts from a feedstock in a system configured to produce ethanol and distillers grains from a fermentation product is disclosed. A system configured to process feedstock into a fermentation product and bioproducts including ethanol and meal is disclosed. A bioproduct produced from a fermentation product produced from a feedstock in a biorefining system is disclosed.
