摘要： PROBLEM TO BE SOLVED: To perform decomposition of dioxins emitted into the environment. SOLUTION: In this treating method for decomposing dioxin using activated sludge, first, the activated sludge is added to mineral nutrient salt culture medium including carbazole (step 101). Secondly, carbazole assimilation fungi which enable assimilating the carbazole in the activated sludge are subjected to enrichment culture (step 102). After the carbazole assimilation fungi subjected to the enrichment culture, subsequently, the material polluted with dioxin is added thereto in a proper stage (step 103).

摘要： PROBLEM TO BE SOLVED: To decompose dioxins discharged into an environment. SOLUTION: In this dioxin decomposition method, first of all, a heterocyclic/ polycyclic aromatic compound serving as a growth substrate is added to a microorganism-containing substance containing various kinds of microorganisms (step 101). After the growth substrate such as carbazole, dibenzofuran, fluorene is added to activated sludge serving as the microorganism-containing sub stance, enrichment culture of a specific microorganism capable of assimilating the growth substance such as carbazole in the activated sludge is carried out (step 102). After the enrichment culture of the specific microorganism in the activated sludge, the microorganism is isolated (step 103), and then, a decomposing enzyme for assimilating the heterocyclic/polycyclic aromatic compound is induced from the isolated microorganism and the decomposing enzyme is added to a dioxin- polluted substance (step 104).

摘要： PROBLEM TO BE SOLVED: To provide an insolubilization method of a toxic material which can prevent a lowering of the ground strength without inhibiting an insolubilization reaction. SOLUTION: An insolubilization agent is added in situ as an insolubilization agent slurry to the ground contaminated with the toxic material. When the insolubilization material is added, a polymer material having the nonionicity and also the water absorbency is loaded with together the insolubilization agent. Concretely, when the toxic material is a cyan or its compound, Fe 2 SO 4 can be used as the insolubilization agent and a nonionic polymer coagulant of a polyacrylamido group can be used as the polymer material. When the polymer material is the nonionic polymer coagulant, its concentration is preferably 0.1-2%. Then, when or after the insolubilization slurry and the polymer material are added, the ground added in situ is stirred and mixed. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide an oxygenase gene that is derived from a microorganism and encodes an oxygenase capable of degrading dioxins, and a method for degrading the dioxins using the enzyme encoded by the gene. SOLUTION: The objective gene encoding a dioxygenase which degrades dioxin skeleton, particularly called angular dioxygenase, is isolated from Terrabacter sp. strain DBF63. The other objective method is based on the successful determination of the base sequence thereof and the finding that dioxins are degraded by the oxidase formed from a transformant that is obtained by transforming Escherichia coli or the like with a vector into which the gene is inserted, and is cultured.

摘要： PROBLEM TO BE SOLVED: To enhance soil washing effect by pulsating ultrahigh pressure air at a short-time interval to continuously blowing the same in the lower part of an aquifer in a moment in an intermittent manner not only to allow air to arrive at the aquifer over a wide range but also to facilitate the peeling of an oil component from soil particles by the blowing force of air and to accelerate microbial biodegradation by bringing ground water to an aerobic state by ultrahigh pressure air not only to enhance the cleaning efficiency of polluted ground water but also to reduce cost. SOLUTION: This method comprises an oil component peeling process wherein ultrahigh pressure air is pulsated at a short-time interval to be intermittently injected in ground water 12 continuously from the injection well 1 positioned at the lower layer of an aquifer 102 to float an oil component adsorbed on soil particles, a ground water recovery process for recovering ground water 12 mixed with the floated oil component from the pumping-up well 18 positioned at the upper layer of the aquifer 102 and an oil-water separation process for separating the recovered ground water 12 into oil and water to remove the oil component and ground water 12 after the oil component is removed is refluxed to the aquifer 102.
