A method of treating hardly decomposable harmful substance comprising (A) a step for adding coagulant into wastewater containing a hardly decomposable harmful substance, (B) a step for performing solid-liquid separation which separates a solid containing the hardly decomposable harmful substance from a liquid, and (C) a step for decomposing the hardly decomposable harmful substance by bringing peroxide into contact with the separated solid. Efficiently and safely treating the hardly decomposable harmful substances by means of low-cost facilities realizes.

Method of treating wastewater containing hardly decomposable harmful substances

The invention provides lignin-degradable fungi capable of degrading dioxins that have accumulated in the soil for farm crops, into harmless substances; a method for degrading dioxins by applying the fungi to a dioxin-containing object to such a degree that the cell concentration in the object reaches at least 1&times;10 cfu per gram of the object; compost containing the fungi; a method for producing compost that comprises a step of thermally fermenting a lignin-containing, plant-derived organic material to be compost, at a temperature falling between 65 and 100&deg; C. for at least 2 hours, followed by inoculating the thus-fermented material with lignin degrading enzymes-producing fungi and further fermenting it; and a method of using the compost for cultivating plants.

Mold capable of degrading dioxin, degradation of dioxin with the use of the same, method for producing composts capable of degrading dioxin and method for growing plants

Sorbic acid can be prepared by the activity of a specific microorganism on 2,4-hexadienal. This method can be performed under mild conditions and, different from organo-chemical methods, is advantageous because no by-products are formed.
