Mushrooms can be used to clean soil

Soil that has been contaminated with organic pollutants, e.g. oil, can be cleaned by composting. However, this method is not effective against many other organic pollutants such as polyaromatic hydrocarbons (PAHs) and dioxins.

Soil contaminated with such substances can be found in the location of fuel distribution networks, waste management and other industries.

As reported ozemle.net for the period 2005-2006 in Finland almost 3 million tons of excavated contaminated soil that cannot be cleaned, it is transported to landfills and other treatment facilities.

Here the soil used for the construction of field structures for new landfill. To date, this is the cheapest and easiest method of disposal.

Another, more expensive way of destroying the contaminated soil is incineration at a temperature of 1000 degrees Celsius in a special unit. This destroyed all organic pollutants.

Mushrooms used to clean soil, grown in pine bark that contains compounds that prevent growth of other microbes.

The growth period lasts from 4 to 6 weeks. In fact, the treatment takes place in the plant where the mycelia of white-rot fungi grown on contaminated soil.

As found by the scientist, growing on wood and in soil, fungi white rot effectively split the contaminating lignin-like compounds.

In the laboratory, the mushrooms were able within three months to clean the soil collected from old sawmills, 96 percent of PAH compounds and 64 per cent of dioxins.
