TECHNOLOGY FOCUS - BIOLOGY - Preferred Method: The method further comprises: inoculating the fermentation suspension with a microorganism (which is yeast) capable of fermenting the fermentation suspension to produce ethanol; distilling the post fermentation beer to collect ethanol without pre-removal of solids from the beer; adding cellulase, xylanase, and/or acid proteolytic enzyme to the suspension fluid; and incubation of the fermentation mixture at 50 degrees C for 24-72 hours. The anaerobic biodigestate results from anaerobic digestion of an organic material. The fractioned anaerobic biodigestate is a liquid fraction generated by removing substantially all solids from the anaerobic biodigestate. The liquid fraction is generated by passing the anaerobic biodigestate through a screw press, or by centrifugation. The liquid fraction is further fortified by a nutrient recovered from the anaerobic biodigestate. The fractioned anaerobic biodigestate is an ultrafiltration concentrate or an ultrafiltration permeate generated from the liquid fraction of the anaerobic biodigestate. The pH of the fermentation suspension is adjusted to below 6, preferably 4-5. The high-starch wheat, corn, or other high-starch crop is converted in the suspending fluid at least partially into simple sugars, and the conversion comprises (with no particular order and no limitation on repeats) mechanical grinding, heating with steam, reacting with an acid, liquefaction by using alpha -amylase, and/or saccharification by using glucoamylase. The pH is controlled in an optimal range required for the wheat or crop conversion reactions. The 75% of the suspension fluid is added before liquefaction, and 25% of the suspension fluid is added post liquefaction and before saccharification. The wet distiller's grains resulting from ethanol distillation is fed to a livestock animal (e.g. swine, poultry, fish and cattle) as feed or used as fertilizers. The pH of the suspending fluid is adjusted to a value for optimal growth of fermentation microorganisms. In the method of hydrolyzing the feedstock, the hydrolyzing step comprises, with no particular order and no limitation on repeats, mechanical grinding, heating with steam, reacting with an acid, liquefaction by using alpha -amylase, and/or saccharification by using glucoamylase. Preferred Components: The suspending fluid comprises anaerobic biodigestate or a fractioned anaerobic biodigestate. The liquid fraction contains 3-9% solids. The high-starch wheat is present at up to 28 wt/vol.% in the suspension fluid. The organic material comprise animal offal, livestock manure, food processing waste, municipal waste water, thin stillage, distiller's grains or other organic materials. The feedstock is high-starch wheat, corn or other high-starch crop. The suspending fluid is substantially free of non-anaerobic microorganisms. The nutrient supplement is a nitrogen supplement. EXAMPLE - In 250 ml flask, dry wheat (28 g) in anaerobic digestate (AD) (100 ml) and water were added. OPTIMASH BG (RTM: beta 3-Glucanase/xylanase mixture) was added for catalysis of non-starch carbohydrates in wheat and/or AD. Liquefaction was processed at 85 degrees C for 1 hour. Then G-ZYME 480 (RTM: 1,4-a-D-Glucan hydrolyase) and OPTIMASH BG (RTM: beta 3-Glucanase/xylanase mixture) were added at 60 degrees C for 30 minutes during saccharification. Super yeast X-press powder was pitched in distill water at 34 degrees C for 20 minutes, and then aliquot was added to the flask with yeast nutrients to start ethanol fermentation, to give ethanol.
