Described is a process for releasing soluble starch hydrolysates or hydrolysed starch syrup from substantially intact corn kernels during high temperature steeping at a temperature at or above the gelatinization temperature of starch in the corn kernels, and the recovery of protein and oil-enhanced, carbohydrate-depleted residuals that are ideally suited for use as high quality animal feed or other food-grade products.

An improved dry grind system and method for producing a sugar stream from grains or similar carbohydrate sources and/or residues, such as for biofuel production. In particular, a sugar/carbohydrate stream, which includes a desired Dextrose Equivalent (DE) where DE describes the degree of conversion of starch to dextrose (aka glucose) and/or has had removed therefrom an undesirable amount of unfermentable components, can be produced after saccharification and prior to fermentation (or other sugar conversion process), with such sugar stream being available for biofuel production, e.g., alcohol production, or other processes. In addition, the systems and methods also can involve the removal of certain grain components, e.g., corn kernel components, including protein, oil and/or fiber, prior to fermentation or other conversion systems. In other words, sugar stream production and/or grain component separation occurs on the front end of the system and method.

The present invention can: efficiently and readily produce glucose from microalgae that accumulate starch in their cells; and obtain ethanol. During a preparation step of the glucose production method, microalgae are prepared on which a saccharifying enzyme acts on starch accumulated inside the microalgae cells, without disrupting the cell walls. In a saccharification step, starch inside the cells is saccharified and glucose is generated, by adding a saccharifying enzyme to the microalgae without a disruption treatment. The ethanol production method has a step in which, after the saccharification step, the glucose undergoes alcoholic fermentation and ethanol is generated.

This disclosure describes processes for using a single cellulosic feedstock or a combination of two or more different cellulosic feedstocks with a starch component to produce a fermented product. The process includes separating the components of the cellulosic feedstocks with fractionation, pretreating a component with wet fractionation with chemicals, hydrolysis and fermentation of the pretreated feedstock(s) to produce cellulosic biofuel. The process may include combining the cellulosic feedstock(s) with other components to a cook and/or a fermentation process, distilling and dehydrating the combined components to produce the bio fuel. The process may also include producing a whole stillage stream from the feedstock(s) and mechanically processing the whole stillage stream to produce a high-value protein animal feed.
