  • Patent number: 7067303
    Abstract: Agricultural biomass hydrolysate is detoxified by culturing in the presence of the fungus Coniochaeta ligniaria (teleomorph) or its Lecythophora (anamorph) state. This organism is capable of significantly depleting the toxicant levels of furans, particularly furfural and 5-hydroxymethylfurfural. A new strain of the fungus has been isolated and deposited in the Agricultural Research Culture Collection (NRRL) in Peoria, Ill., as Accession No. NRRL 30616. The detoxified agricultural biomass hydrolysate is useful as a substrate for industrial fermentation processes, especially in saccharification treatments for bioethanol production.

    Abstract: A culture material is formed containing a water-soluble polymer layer and a porous matrix layer arranged such that when water is applied to the surface of the matrix layer the water diffuses through the matrix layer to dissolve the water-soluble polymer layer which then gradually penetrates into the matrix layer to form a single layer for use as a culture medium on which a microorganism can be grown to form colonies. The water-soluble polymer layer or water added to the matrix layer can contain nutrients for the microorganism, and the microorganism can be added with the water. The culture material has a water content of not more than 50%, and is sufficiently insoluble in water such that it substantially holds its original shape for at least 30 minutes when in contact with water having a temperature of not more than 50° C.
