Fungal Biosorption of Heavy Metals

Fungal biosorption is a method for removing dissolved metal ions from water by using fungal biomass as a binding material. It is important to define this process accurately: metals cannot be biodegraded or destroyed in the way that many organic pollutants potentially can. Biological treatment may change a metal’s chemical form, oxidation state, solubility, mobility … Read more

Integrating Mushroom Growing with a Small Farm or Homestead

On a small farm or homestead, mushroom growing does not have to be an isolated hobby with its own separate materials, equipment and waste stream. It can fit between activities that are already taking place: growing crops, managing shelterbelts and woodland, maintaining gardens, making compost and producing food. The basic idea is integration. A material … Read more

Choosing Mushroom Spawn for Home Growing

Choosing the right mushroom spawn is one of the first important decisions in a home-growing project. The best format depends less on which product sounds most advanced and more on the mushroom species, the growing material, and whether you plan to fruit indoors or outdoors. What is mushroom spawn? Spawn is a growing material that … Read more

How to Start an Outdoor Mushroom Bed

An outdoor mushroom bed brings fungi into the productive garden alongside vegetables, herbs and fruit. Instead of growing mushrooms in a bag or kit indoors, you introduce suitable spawn into an organic substrate and give the mycelium time to colonise it. When moisture, temperature and other conditions are right, the established fungus can produce mushrooms … Read more

Turning Local Tree Waste Into Fungal Resources

Local tree maintenance produces a steady stream of branches, logs, pruning material and woodchips. With careful sorting and handling, these materials can support community mushroom projects, garden systems, habitat work and longer-term decomposition. Instead of treating all woody material as waste, organisations can view clean local biomass as a resource that moves through a circular … Read more

How Fungi Break Down Hydrocarbon Pollution

Hydrocarbon contamination occurs when compounds made primarily of carbon and hydrogen enter soil, sediment, surface water or groundwater. In environmental work, the term often refers to petroleum contamination from crude oil and refined products. Common sources include oil spills, leaking storage tanks and pipelines, gasoline, diesel, kerosene, jet fuel, lubricating oils, used motor oil, refinery … Read more

Creating a Circular Organic-Waste System on a Lifestyle Block

A lifestyle block can generate a surprising volume of organic material: grass clippings, fallen leaves, pruning material, crop residues, straw, clean woodchips, suitable logs and residues from mushroom growing. Instead of treating all of these materials as waste, it is useful to view them as biological resources that can be sorted, processed and returned to … Read more

Growing Oyster Mushrooms on Straw at Home

Moving from a ready-made mushroom kit to your own bulk substrate is a rewarding next step. Oyster mushrooms are among the most approachable species for home cultivation because they grow vigorously on a range of plant materials, including clean cereal straw. With suitable spawn, careful moisture control and a reasonably clean working method, a simple … Read more

Living vs Dead Mycelium in Environmental Remediation

Living fungal biomass and dead or inactivated fungal biomass can both contribute to environmental remediation, but they do so through fundamentally different mechanisms. Living fungi rely on ongoing physiology: metabolism, growth, enzyme production and interactions with surrounding organisms. Dead biomass functions mainly as a nonliving sorbent whose cell-wall chemistry can capture contaminants without requiring biological … Read more
