Abstract: The present invention provides a method for producing an ethanol from a lignocellulose resource efficiently. According to the method for producing the ethanol of the present invention, an enzyme group derived from a mushroom waste substrate has a high activity and can allow cellulose or xylan in the lignocellulose resource to be efficiently converted into glucose or xylose. That is, the lignocellulose resource can be converted into a saccharified solution including the glucose or xylose thereinside. The glucose or xylose in the saccharified solution can be converted into the ethanol by fermentation of yeast or bacterium provided into the saccharified solution. The method for producing the ethanol of the present invention can allow the ethanol to be efficiently produced from the lignocellulose resource.

Abstract: Improving the beneficial use of waste material from a vegetation source, a biomass is fermented to produce a bio-fuel and carbon. The bio-fuel can be at least ethanol and bio-diesel and the resulting carbon can used to produce ink for printers. When the biomass is tree matter, a biocatalyst can extracted from the tree matter prior to fermentation. A component of the biocatalyst is used to cleanse internal combustion engine exhaust emissions by spraying the biocatalyst onto a exhaust emission gas. The sprayed exhaust emission gas can be filtered and the filtration by-product can be collected.

Abstract: A process for the preparation of an aqueous hinokitiol solution, characterized by mixing hinokitiol or hinokitiol containing oil with water, boiling the obtained liquid mixture by heating, rapidly cooling the resulting liquid mixture, blowing oxygen into the liquid mixture under stirring, and storing the obtained liquid mixture at a temperature of 0.5 to 5.degree. C. The process can give an aqueous solution of the water-insoluble essential oil having a concentration of up to about 40%. This aqueous solution of the oil is easily handleable by virtue of its liquidness, and does not contain any organic solvent harmful to the human body, thus being highly safe. Further, the solution has antibacterial and/or microbicidal effect.
