Dear Megan Shoemaker ,

There are several methods that can be used to separate mycelium from soil, depending on the specific goals of your project and the resources available to you. Some common methods include:

It's worth noting that some of these methods may not be effective depending on the type of soil and mycelium you're working with, so it's a good idea to try out a few different methods and see which one works best for your specific project.

There are several methods for extracting mycelium from soil in mycoremediation projects, including,

Physical separation: This method involves physically removing the mycelium from the soil using tools such as tweezers or a scalpel. This method is generally used for small-scale extraction and is not suitable for large amounts of soil.

Washing: This method involves washing the soil mycelium mixture with water or a solution to remove the soil and leave the mycelium behind. The mycelium can be collected by using a filter or centrifugation.

Enzymatic digestion: This method involves using enzymes to break down the soil and release the mycelium. Cellulase or other enzymes that can degrade plant cell walls can be used to digest the soil.

Solvent extraction: This method involves using a solvent to dissolve the soil and leave the mycelium behind. Common solvents used include ethanol, methanol, and chloroform.

Incubation: This method involves incubating the soil-mycelium mixture at the optimal conditions for mycelium growth, and then removing the mycelium by washing or centrifugation.

Selective media: This method involves growing the mycelium on selective media, which promotes the growth of the mycelium while inhibiting the growth of other microorganisms in the soil.

Magnetic separation: this method is based on the magnetic properties of the mycelium. By using magnetic beads or nanoparticles that bind to the mycelium, it is possible to separate it from the soil through a magnetic field.

Microfiltration: this method uses a membrane with a pore size that allows the mycelium to pass through and retain the soil particles.

It's important to consider the characteristics of your sample, the pollutants you want to test and choose the appropriate method accordingly. Additionally, testing for pollutants can be done using techniques such as microscopy, PCR, and mass spectrometry.
