Most do not increase digestibility to the maximum possible. The few that do allow maximum digestion use too much fuel,- use expensive or toxic chemicals, or generate toxic products.” Alkaline hydrogen peroxide dissolved - most of the hemicellulose and more than half the lignin in chopped wheat straw within 12 hours, Gould says. The treatment also “opened” a crystalline, indigestible part of the cellulose to digestion by an enzyme from the fungus, Trichoderma. The enzyme converted more than 95 percent of the cellulose in the treated straw to glucose sugar. It converted less than 20 percent of For All Your Form Building Needs. Large or Small.

A yeast, Saccharomyces, con verted the glucose to ethyl alcohol, yielding about 90 percent of all the alcohol that the straw cellulose could produce. Gould compared the yeast’s growth and alcohol production on the cellulose, on a medium containing the dissolved lignin and on a conventional fer mentation medium. “Neither the lignin-containing solution nor the treated cellulose appeared to be in any way toxic or inhibitory to the yeast’s growth or ethanol production,” he says. “This is especially important since peroxide-treated crop residues may find use as high energy feeds for ruminants.” Insoluble material, mostly lignin, remaining after both peroxide treatment and enzymic digestion amounted to 7 percent of the original straw. “In other words,” Gould says, “93 percent of the original straw was solubilized by the combined treatment with alkaline peroxide and Tricboderma enzyme. ” “The new lignin products formed during the peroxide reaction in clude low molecular weight car boxylic acids. They have potential as chemical feedstocks.” For mation of these products instead of phenolic acids formed in other treatments may account for tbp lack of toxicity in lignin dlssovled in the peroxide treatment, Gould says.
