Wouldn't it be amazing if there was a natural none- invasive
way of cleaning up pollution in our environment. A method that would positively
impact other species, and not kill them in the process.
Bioremediation has been used for centuries throughout
the world. Bioremediation is any process that uses micro-organisms,
plants, fungi or their enzymes to return a polluted environment to a less
polluted state.
One form of
bioremediation is called Mycoremediation. It is a newer science started around the beginning
of the 20th century. It is the process of using fungi to remove or
break down toxins in an environment.
Mycoremediation is a combination of two words,
Myco is for mycology the study of fungus
(mushrooms)
Remediation is the correction of something bad.
It
was coined by Paul Stamets, who is the leader in this field. He has written several
books one titled, “Mycelium Running - How mushrooms can save the world.”
In this book he comments “Fungi are the grand
recyclers of our planet, the mycomagicians, dissembling large organic molecules
into simpler forms, which in turn nourish other members of the ecological
community. Fungi are the interface organisms between life and death.”
There are certain types of fungi being studied such as
oyster mushrooms. Oyster Mushrooms have been able to remove toxins such as oil, radiation, pesticides, petroleum products, PCB’s,
and other pollutants.
So how does it work?
There is more to the mushroom than just what you see
above ground. Under the soil there is a vegetative part of fungus called
mycelium. Mycelium is a mass of thread like hyphae.
Hypha (plural hyphae) is a long, branching
filamentous structure of a fungus. The mycelium stretches out and grows as long
as it can gain nutrients. A mushroom is the fruiting body that will grow off
the mycelium when the conditions are right.
The mycelium grows and form mycelial mats. These
mycelial mats are the key. The mycelia are the magic.
There are three ways to apply the science of Mycoremediation on a toxic
area.
1.) Mixing
mycelium into contaminated soil
2.) Placing
the mycelial mats over the toxic sites
3.) Or a
combination of these techniques, in one or
more treatments.
Once applied the natural processes of
nature take place. The mycelium will break the toxins down then digest them.
When heavy metals need to be removed from the soil the mycelium will
fruit. The fruit bodies (mushrooms) absorb
the toxins as nutrients.
Studies have shown that after treatment life will
return to a previously toxic non inhabitable area. More studies are currently underway to test
mycelium against radiation in the soil in Japan.
There are still many questions and much to learn.
Mycoremediation is still a new branch of bioremediation. The lack of
information in the field has caused it to advance slowly but the research
continues and grows.
It is important for our species to look for new
opportunities to live a sustainable life with the environment around us. We need
more options not more man-made chemicals.
