Hazardous environmental pollutants decomposition method using the edible mushroom

摘要

PROBLEM TO BE SOLVED: To decompose pollutants without affecting the human body and an ecological system by charging edible mushroom hyphae, cultured hyphae and/or a mushroom bed into polluted soil or a water area. SOLUTION: In the decomposition of PCB and/or dioxins as organic chlorine compounds, edible mushroom hyphae, cultured hyphae and/or a mushroom bed are charged into polluted soil or a water area. In this process, lignosulfonic acid or the sulfonate substance of a lignin-containing substance is charged during the charging or before/after the charging. The edible mushroom to be used is selected from gifola fronlosa, dentinula edodes, dyephyllum shimeji, and Flammulina volutipers, and at least one kind of Maitake selected from white-Maitake, kite-Maitake, and others is used preferably. The lignosulfonic acid or the sulfonated substance of a lignin-containing substance can be charged into the soil or the water area simultaneously with the hyphae and occasionally after the charging into the hyphae and others.
