What is Bioremediation?

Bioremediation is the use of microorganisms, plants, and fungi to remove or neutralize contaminants; allying with living systems to detoxify contaminated environments. Many micro-organisms, plants and fungi are able to bind, extract or transform contaminants to create less toxic, healthier, and increasingly resilient ecosystems. 

This class will provide an introduction to different bioremediation tools and techniques for detoxifying and revitalizing the gardens, lands and waters that sustain and nourish our communities, highlighting bioremediation projects and inspiring practitioners who are working with regenerative remedies to heal toxic realities. 

Defining Terms 

  • Microbial Remediation: Treating contaminated areas with microorganisms to remove and break down pollutants
  • Mycoremediation: Cleaning water, and soil with fungi
  • Phytoremediation: Cleaning water, and soil with plants

Interested in mushrooms and mycology? We recommend Mushroom Grower’s Toolkit. The next cycle will be announced soon, but in the mean time, take a look at the course webpage.


A core component of this course – and every Earth Activist Training course – is our private forum: Earth Activist Training Online network. This platform is where you will find course resources, your homework, and a network to connect with classmates and other Earth Activist students. 

Recordings of each class will be available to you as a resource. You will have access to the course for a year after the course ends should you want to deepen your understanding of the material.
