peroxidases and cellulases which have
unusually powerful degradative properties.
These extracellular enzymes have evolved to
break down plant fiber, primarily lignin-cellulose, the structural component in woody
plants, into simpler forms. By happenstance,
these same enzymes also reduce recalcitrant
hydrocarbons and other man-made toxins.

Given the number of industrial pollutants that

are hydrocarbon-based, fungi are excellent
candidates for toxic waste clean-up and are
viewed by scientists and government agencies with increasing interest. Current and
prospective future uses include the detoxification of PCB (polychiorolbiphenols), PCP
(pentachlorophenol), oil, pesticide/herbicide
residues, and even are being explored for
ameliorating the impact of radioactive
Bioremediation of toxic waste sites is especially attractive because the environment is
treated in situ. The contaminated soils do not
have to be hauled away, eliminating the extraordinary expense of handling, transportation, and storage. Since these fungi have the
ability to reduce complex hydrocarbons into
elemental compounds, these compounds

pose no threat to the environment. Indeed,
these former pollutants could even be considered as "fertilizer", helping rather than
harming the nutritional base of soils.
Dozens of bioremediation companies have

formed to solve the problem of toxic waste.
Most of these companies look to the imper-

fect fungi The higher fungi should not be
disqualified for bioremediation just because
they produce fruitbody. Indeed, this group
may hold answers to many of the toxic waste

The most vigorous rotters de-

scribed in this book are the Ganoderina and


Pleurotus mushrooms. However, mushrooms
grown from toxic wastes are best not eaten as
residual toxins may be concentrated within
the mushrooms.

Mushroom Mycelium and
The mycelium is fabric of interconnected,
interwoven strands of cells. A colony can be
the size of a half-dollar or many acres. A cu-

bic inch of soil can host up to a mile of
myceium. This organism can be physically
separated, and yet behave as one.

The exquisite lattice-like structure of the
mushroom mycelium, often referred to as the
mycelial network, is perfectly designed as a

filtration membrane. Each colony extends
long, complex chains of cells that fork repeatedly in matrix-like fashion, spreading to
geographically defined borders. The mushroom

mycelium, being a voracious forager for carbon and nitrogen, secretes extracellular
enzymes that unlock organic complexes. The
newly freed nutrients are then selectively absorbed directly through the cell walls into the
mycelial network.

In the rainy season, water carries nutritional particles through this filtration membrane, including bacteria, which often be-

come a food source for the mushroom
mycelium. The resulting downstream effluent
is cleansed of not only carbon/nitrogen-rich

compounds but also bacteria, in some cases
nematodes, and legions of other micro-organisms. Only recently has the classic
saprophyte, the voracious Oyster mushroom,
been found to be parasitic against nematodes.
(See Thorn & Barron, 1984). The extracellular enzymes act like an anesthetic and stun
the nematodes, thus allowing the invasion of
