“Numerous pretreatments have
been developed to increase the
susceptibility of cellulose in
agricultural residues and wood to
digestion by enzymes,” Gould
says. “These pretreatments all
seem to have some major
drawback. 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

digests
the cellulose in untreated straw to
the sugar.
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.
