Fungi cultivation on alcohol fermentation stillage for useful products and energy savings
ActiveUS20100196994A1Easy to dehydrateEasy to shapeFungiEnergy based wastewater treatmentAirlift reactorGlycerol
A method of processing stillage from fermentation derived alcohol is disclosed, including dry-grind ethanol production from corn, by fermentation with filamentous fungi. This produces high-value fungal biomass that can be recovered by screening, is easily dewatered and used as an animal feed, human food or as a source of nutraceuticals. The methodology uses an airlift reactor to enhance the morphology of the fungi for easy harvesting and separation of water for recycling and reuse and to recover added enzymes and mineral acid with the water. The process also separates oil from the stillage. The fungal processing removes organic substances from the water that are otherwise inhibitory to the reuse prospects for the water, i.e. suspended and dissolved organic matter, including glycerol, lactic and acetic acids. The process also separates oil from the stillage by enmeshing the oil in the fungal biomass and can produce more oil through cultivation of oleaginous fungi. This approach generates revenue from low value thin stillage, while substantially reducing stillage processing costs, mainly by averting the need for evaporation of the thin stillage.

Compositions and methods for mycotoxin decontamination of animal feed, food, soil and plants using biomass of filamentous fungi and its selected components
InactiveUS20120027747A1Easy to handleWide rangeBiocideAntinoxious agentsChemical treatmentFood additive
A method of rendering harmless mycotoxins contaminating food, animal feed and assisting infection of plant hosts by microbial parasites is proposed. The method comprises binding mycotoxins by a novel adsorbent, consisting partially or in full of the biomass of filamentous fungi or isolated fungal biomass components, such as chitin, chitozan and hyrdophobins, or fungal biomass enriched in its capacity to bind said mycotoxins using fungal species and strain selection, genetic engineering of fungi, modification of fungal fermentation conditions and downstream physical and chemical treatment of fungal biomass, such as milling or micronization in a dry state. The resulting adsorbent can bind a wide range of mycotoxins, including the ones difficult to bind (Ochratoxin, T-2, DON, NIV) using a current generation of mycotoxin adsorbents based on clay, resins, yeast and bacterial biomass. The adsorbent can be used as an animal feed additive, functional food additive and agricultural fungistatic / fungicide.
