Bioremediation is a viable and cost effective remediation method for soil contaminated with a variety of chemical pollutants. White-rot fungi, with emitting extracellular free radicals, are known to be able to decompose lignin, which is usually hardly biodegradable with most of bacteria. The decomposition mechanism has been shown to be attributed, at least in part, to lignolytic peroxidases, and thus is considered to be quite unique system, being different from bacterial function.
In general, bioremediation method has drawbacks; uncertainty of microbial pathogenicity to human and difficulty to prepare enough microorganisms. In order to overcome these weaknesses, we have developed new bioremediation method which utilizes waste of edible mushroom cultivation as microbial source, and found these waste materials show high lignolytic peroxidase activity.
