摘要： The present invention relates to a composition for preventing odors containing odorless microorganisms or a culture thereof. The present invention also relates to a method for preventing odors including coating the composition for preventing odors. When a biofilm is formed by coating an object offensive odor-generating microorganisms can inhabit with the composition for preventing odors of the present invention, odors can be effectively prevented by significantly preventing the inflow and inhabitation of outside microorganisms that may generate offensive odors.

摘要： Disclosed are a polymer gel electrolyte composition, a polymer gel electrolyte prepared from the composition, and a lithium secondary battery including the electrolyte are proposed. The polymer gel electrolyte may be formed by thermal cross-linking of the polymer gel electrolyte composition including an ether-based organic solvent with excellent compatibility with a lithium metal anode, a nitrate capable of forming a stable film on an electrode surface, and an appropriate ratio of a cross-linking agent having two or more acrylate functional groups. Therefore, the polymer gel electrolyte can smoothly penetrate the anode to form an ion transport channel and improve oxidation stability through interaction between the polymer and the solvent thereof, thereby improving battery life.

摘要： Disclosed is a coating composition for preventing odor. The coating composition may include one or more types of odorless microorganisms selected from the group consisting of Caulobacter vibrioides, Bradyrhizobium diazoefficiens, Bradyrhizobium daqingense and Methylobacterium brachiatum or a culture solution thereof. Further provided is a method for preventing odor, and the method may include applying the coating composition for preventing odor. When a biofilm is formed from the microorganisms in the coating composition by coating an object on which an odor-causing microorganism can live, the inflow and the inhabitation of external microorganisms generating odor may be significantly blocked, thereby enabling odor to be effectively prevented.
