Patent 11407973 - Methods for culturing filamentous fungi in fermentation media > Claims

  • 1. A composition, comprising: an air-medium colloid (AMC), comprising: a fermentation medium; andair, colloidally dispersed throughout the fermentation medium; anda biomass, in the form of a coherent mat, of a filamentous fungus, cultured in or on the AMC.
    • 2. The composition of claim 1, wherein the AMC further comprises a stabilizer.
      • 3. The composition of claim 2, wherein the stabilizer is selected from the group consisting of a polysaccharide gum, an anionic surfactant, a cationic surfactant, ceteareth 20, cellulose, diacetyl tartaric esters of mono- and diglycerides (DATEM), a diglyceride, an emulsifying wax, glycerol monostearate, a lecithin, a monoglyceride, a mustard, a non-ionic surfactant, a soap, a sodium phosphate, sodium stearoyl lactylate, a zwitterionic surfactant, a saponin, a starch, a modified starch, a plant protein surfactant, an animal protein surfactant, microparticulates, silica, and combinations and mixtures thereof.
        • 4. The composition of claim 3, wherein the stabilizer comprises xanthan gum.
      • 5. The composition of claim 2, wherein a mass ratio of the fermentation medium to the stabilizer in the AMC is between about 100:1 and about 1,000:1.
    • 6. The composition of claim 1, wherein a volume fraction of air in the AMC is between about 0.05 and about 0.95.
      • 7. The composition of claim 6, wherein the volume fraction of air in the AMC is between about 0.3 and about 0.7.
    • 8. The AMC composition of claim 1, wherein the AMC is a foam that is stable over at least about 1 day.
      • 9. The AMC composition of claim 8, wherein the foam is stable over at least about 3 days.
    • 10. The composition of claim 1, wherein the filamentous fungus belongs to an order selected from the group consisting of Ustilaginales, Russulales, Polyporales, Agaricales, Pezizales, and Hypocreales.
    • 11. The composition of claim 1, wherein the filamentous fungus belongs to a family selected from the group consisting of Ustilaginaceae, Hericiaceae, Polyporaceae, Grifolaceae, Lyophyllaceae, Strophariaceae, Lycoperdaceae, Agaricaceae, Pleurotaceae, Physalacriaceae, Omphalotaceae, Tuberaceae, Morchellaceae, Sparassidaceae, Nectriaceae, and Cordycipitaceae.
    • 12. The composition of claim 1, wherein the filamentous fungus belongs to a species selected from the group consisting of Ustilago esculenta, Hericulum erinaceus, Polyporous squamosus, Grifola fondosa, Hypsizygus marmoreus, Hypsizygus ulmarius, Calocybe gambosa, Pholiota nameko, Calvatia gigantea, Agaricus bisporus, Stropharia rugosoannulata, Hypholoma lateritium, Pleurotus eryngii, Pleurotus ostreatus, Tuber borchii, Morchella esculenta, Morchella conica, Morchella importuna, Sparassis crispa, Fusarium venenatum, MK7 ATCC Accession Deposit No. PTA-10698, Disciotis venosa, and Cordyceps militaris.
    • 13. The composition of claim 1, wherein the AMC further comprises a food-grade or food-safe additive.
    • 14. The composition of claim 1, wherein the filamentous fungus is selected from Fusarium venenatum and MK7 ATCC Accession Deposit No. PTA-10698.
      • 15. The composition of claim 14, wherein the filamentous fungus is MK7 ATCC Accession Deposit No. PTA-10698.
