TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Process: The second generation process for producing bioethanol is integrated into a first generation bioethanol process utilizing sugar(s) and/or starch or wheat. The second generation process comprises ethanol production from pentose sugars released from lignocellulosic feed-stock. The lignocellulosic feed-stock is supplied at low concentrations. The lignocellulosic feed-stock is supplied into a dry mill. The fungal cultivation step takes place in an airlift reactor and/or bubble column. Preferred Components: The fungi introduced in the fungal cultivation stage are filamentous fungi. The filamentous fungi are food-related strains of Ascomycetes such as Neurospora intermedia, Rhizopus sp., Fusarium venenatum, Aspergillus oryzae, and/or Monascus purpureus. The lignocellulosic feed-stock is maize stover, wheat straw and/or switch grass. The DDGS according comprises 5 g/l fungal biomass, 5 g/l yeast biomass and 15-20 g/l residue mass from the feed-stock before drying. The DDGS comprises between 3-7.5, 4-6 or 4.5 -5.5 g/l, fungal biomass, 3-7.5, 4-6 or 4.5-5.5 g/l yeast biomass and 13- 17.5, 14-16, 18-20, 15-17 or 14.5-15.5 g/l residue mass from the feed-stock before drying. The fungal biomass or a DDGS is produced from the thin stillage of a starch-based first generation ethanol producing process. The crude protein content of the biomass is 40-60 (preferably 50) wt/wt.%. The fungal biomass comprises essential amino acids, omega-3 and/or omega-6 fatty acids. The human food product, food supplement, animal feed and/or fish feed comprises: at least 5 wt/wt.% or at least 7.5 wt/wt.%, preferably 10 wt/wt.%, 20 wt/wt.%, 30 wt/wt.%, 40 wt/wt.%, 50 wt/wt.%, 60 wt/wt.%, 70 wt/wt.%, 80 wt/wt.%, 90 wt/wt.% or 99 wt/wt.% or 100 wt/wt.% nutrient source of the total dry weight of the food product, food supplement or feed as a substitute for, or a supplement to the standard protein source. ACTIVITY - Anabolic; Metabolic.    MECHANISM OF ACTION - None given.    EXAMPLE - Ethanol processes in dry mills produce ethanol and animal feed from whole grains, where the wastewater after the distillation and separation of solid materials was called thin stillage. In this work, similar production of 3.5 g/l ethanol and 5 g/l biomass from thin stillage was obtained during batch cultivation of the edible fungus Neurospora intermedia in a 2 m high airlift reactor and bubble column. The fungal biomass, containing protein 50 wt/wt.% and lipids 12 wt/wt.%, was rich in essential amino acids and omega-3 and omega-6 fatty acids. In continuous mode of fermentation, dilution rates of up to 0.2 hour-1 could be applied without cell wash-out in the bubble column at 0.5 vvm. At 0.1 hour-1, around 5 g/l ethanol and 4 g/l biomass containing ca 50% protein were produced. The fungus was able to assimilate oligomers in the liquid fraction as well as sugars backbones such as xylan and arabinan in the solid fraction. The inclusion of the current process provides 11000 m3 ethanol, around 6000 tons of high-quality biomass for animal feed, and energy savings considering a typical facility producing 200000 m3 ethanol/year.
