20130337483 | SYSTEMS AND METHODS FOR FEEDSTOCK QUALITY ASSESSMENT - 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. | 12-19-2013 |
20130344557 | SYSTEMS AND METHODS FOR IMPROVING ETHANOL YIELD - 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. | 12-26-2013 |
