摘要： A method is provided for increasing the solubility of an enzyme in an aqueous solution comprising providing a water-soluble anionic surfactant to the solution and further providing the solution with a pH above that which result in the formation of an enzyme/surfactant precipitate. The application is further directed to an aqueous solution containing an anionic surfactant and having an enzyme concentration contained therein which is higher than that possible in the absence of the surfactant.

摘要： The present invention is directed to silicon carbide whisker recovery from a mixture of silicon carbide whiskers and carbonaceous silicon carbide particles. The invention involves shredding the mixture down to a specified size, dispersing the mixture in water to form an aqueous mixture, mixing in an effective amount of flocculating agent, agitating the aqueous mixture, mixing the aqueous mixture with an immiscible organic liquid, agitating the resulting water-organic liquid mixture, allowing settling of the aqueous mixture and organic liquid so as to establish two liquid phases, separating the two liquid phases into an organic liquid phase and an aqueous phase and, lastly, performing a solid-liquid separation on the aqueous phase, thereby obtaining from the aqueous phase the desired silicon carbide whiskers.
