With the continuation of pollutants entering our environment,
starting with soil, creates a huge impact as we rely on soil for vegetation and
agriculture purposes. With contaminants seeping into soil specifically
petroleum, our livestock and crops would be affected, affecting us in the end as
we eat them including other soil dependent organisms. Decreasing contaminates
in the soil goes through a process called bioremediation, being the most effective
way of removing pollutants in soil. How would this work though, what machine
can do such a thing? That’s where mushrooms come into play, specifically Agaricomycetes
mushrooms. In this study different concentrations of spent mushroom compost were
tested in removing petroleum in contaminated soil with or without added soil enriching
compounds. By increasing the amount of
mushroom concentration, the lower amount of petroleum was found in soil after.
With 10% of spent mushroom compost and fertilizer removed 65% of total
petroleum hydrocarbons, so with the added 10% of SMC, contaminated soil with
petroleum was seen to degrade over a short span so bioremediation did increase
with the addition of mushrooms. By using Agaricomycetes for the
degradation of petroleum contaminated soils, not only is this an
environmentally friendly technique but by using mushrooms to combat pollutants
from entering our soils will be a good sustainable way for farmers etc. to clean
up/repair the quality of their soils. The positive impact of using
Agaricomycetes to reduce pollutants in soil is environmentally friendly that
won’t affect anything negatively as it is a natural process of decomposition just
faster and ecofriendly. Cost and benefits for whether a reduction of petroleum contaminants
in our soil gets better can easily lower the probability of petroleum getting into
water resources that can cause cancer and therefore increase our sustainability.

This was a really interesting topic. I am curious on what properties of the mushroom species in the study allows for it to absorb the petroleum. Thus, I think the next thing to test would be if these mushroom species can survive in different types of environment settings and if there are any limitations in this study.
