Soil Remediation With Plant-Fungal Combinations

zorka portfolio
Description

Ectomycorrhizal mediated remediation of phenolicbased contamination.

This process applies to remediation and restoration of soils contaminated by fuel, polychlorinated biphenyl wastes, etc. While there can be a general beneficial effect of microbial communities, individual plant-fungus combinations can vary in their efficacy in removal of pollutants from the environment. Selection of the most effective combination of plants and fungi is very important for achieving the desired benefits. Not all fungi are created equal as some die off in contaminated soils. Having a set of enzymes from fungi specifically adapted to conditions in contaminated soils and use of native plant/fungal combinations is a huge advantage. Ectomycorrhizal (EM) mediated remediation of phenolic-based contamination through use of specifically adapted Soil and enzyme utilizes plant/fungal combinations that are specifically adapted to conditions created by phenolic application to soils and abilities of ectomycorrhizal fungi to oxidize these compounds. This platform can be adapted to other ecosystems through field assessments of the EM community in each new site.
