Abstract:
PURPOSE: Provided are surfactant compositions to enhance the absorbency of fungicide, dimethomorph, into plant leaf thereby reducing the dosage while increasing protecting/curing effect of the fungicide. A fungicide composition containing them, non ionic surfactant and agriculturally allowed carrier is also described. CONSTITUTION: The compositions are comprised of non ionic surfactant, 0-20wt.% additional emulsifier or assistant dispersants and 0-97wt.% carrier. The surfactants are at least one selected from polyoxyethylene stearyl ether, polyoxyethylene cetyl ether, polyoxyethylene oleyl ether and polyoxyethylene lauryl ester where the additional polymerization rate of ethylene oxide is 5-25 moles. The additional emulsifier and assistant dispersant are selected from polyoxyethylene nonylphenyl ether, polyoxyethylene tristearylphenyl ether, polyoxyethylene polyoxypropylene tristearyl ether, polyoxyethylene alkylaryl sulfonate, sodium dodecylbenzene sulfonate and sodium dioctylsulfosuccinate. The carriers are water, non water soluble organic solvent, water mixed organic solvent, natural or synthetic minerals and natural or synthetic polymers.

Abstract:
The present invention provides xylosidase having amino acid sequence described in second sequence in a sequence listing. More specifically, the xylosidase of the present invention has heat resistance and alkali resistance. The xylosidase reduces wastes and expensive purification costs by replacing conventional chemical methods, and can be used for manufacturing raw materials such as substitute raw materials for fuel, special functional materials, bio polymers, and the likes by being utilized in a saccharification process of fiber based biomass, in forage industries, and paper and detergent industries by showing excellent xylene decomposition activities.
Abstract:
The present invention relates to a method for preparing cellulose derivatives from biomass comprising the following steps: treating room temperature ionic liquid with biomass including cellulose, hemi-cellulose and lignin, and dissolving the cellulose; removing the room temperature ionic liquid and recrystallizing the cellulose; and making a functional-group-introducing agent to contact with the recrystallized cellulose, and introducing a functional group to the cellulose in order to obtain cellulose derivatives. The present invention excludes effects of foreign substances and excessive decomposition products generated in existing pre-processing steps, reduces costs, prevents environmental contamination by simplifying processes and recycling the room temperature ionic liquid, concurrently obtains various cellulose derivatives and saves energy consumed for pre-processing by processing the steps at the room temperature.
