摘要： PROBLEM TO BE SOLVED: To obtain a soil conditioner useful for raising a lawn grass, etc., without polluting an environment by grinding lumbered wood into small pieces by efficient use of lumbered wood, by primarily fermenting a readily decomposable component under specific conditions to produce a half aged ground wood. SOLUTION: Lumbered wood is ground into small pieces, which are piled to form a ridge at a fixed height. The ridge is allowed to stand in an open air storage at it is for a fixed period and a readily decomposable component and a half aged ground wood is produced to utilize the lumbered wood. A charcoal layer 3 is laid on the ground, the layer 2 of the half aged ground wood is placed the charcoal layer and sand is sprinkled in a fixed thickness on the layer 2 of the half aged ground wood to cover the layer with a sand layer 4, which is used as soil dressing.

摘要： PROBLEM TO BE SOLVED: To improve a decomposition efficiency when petroleum compds. are decomposed by culturing microbes, by removing decomposed products of petroleum compds. from a culture medium in a period of culturing and then newly adding a culture medium containing a nitrogen source and phosphorus source and microbes having ability to decompose petroleum compds. SOLUTION: In the decomposing method of petroleum compds. by culturing microbes having ability to decompose petroleum compds. in a culture medium containing petroleum compds. when a soil contaminated with petroleum compds. is recovered, decomposition products of the petroleum compds. are removed from the culture medium in the culturing period. After that, a process to add a culture medium containing at least one kind of nitrogen source and at least one kind of phosphorus source and microbes having ability to decompose petroleum compds. is newly carried out. This process is carried out periodically or not periodically. The decomposition products of petroleum compds. from the culture medium are removed by using a difference in solubility between the decomposition products and the residual compds. or a difference in specific gravity between these.

摘要： PROBLEM TO BE SOLVED: To enhance the ability of decomposing dioxins by a basidiomycete, by cleaning contaminated soil with the dioxins by using compost which is obtained by composting wood by using the basidiomycete. SOLUTION: Wood such as a Japanese cedar, a hinoki cypress and a pine tree, and, furthermore miscellaneous trees, pruned branches and leaves, and mowed grass is composted by a basidiomycete such as Pleurotus ostreatus (an oyster mushroom), Trametes versicolor, Caliolus (Calios versicolor) and Hypoxylon deustoram. By using the resulting compost, the contaminated soil with dioxins is cleaned; the dioxins, comprised of organic compounds such as polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofrans, causes toxic symptoms such as decrease in weight, thymitis-atrophy, liver-toxicity, immnunity-toxicity, development-toxicity, carcinogenesis, teratogenicity and endocrine-disturbance.

摘要： PROBLEM TO BE SOLVED: To detect yeasts and actinomyces in natural and human environments in high sensitivity by using the DNA extracted from microorganisms in the environment through two specific washing treatment as a template, selecting a specific sequence as a primer and subjecting them to polymerase chain reaction. SOLUTION: An environment sample is subjected to the following two washing treatments: (A) the first washing treatment in which the sample is washed with a weak-acidic aqueous solution containing an inorganic or organic slat or an aqueous urea solution and (B) the second washing treatment in which the sample is washed with an aqueous solution of powered milk to extract DNA from the environmental microorganisms in the environmental sample. The extracted DNA is used as a template and the primers of formula I and formula II are used to effect PCR. Then, the amplified DNA fragment is hybridized with the DNA of formula III whereby the yeast in the environment can be detected. In the meantime, PCR is performed by using the primers of formula IV and formula V, the DNA of formula IV is used to effect hybridization whereby the actinomyces in the environment are detected.
