    摘要: A support for enzyme immobilization is described, which is for immobilizing enzymes of various molecular sizes and also for, due to the modification of the surface silanol groups of porous silica particles, for immobilizing various kinds of enzymes, and enables the design of an immobilized enzyme, which exhibits an activity equivalent to that of the corresponding non-immobilized enzyme and withstands repeated use. A method for producing the support is also described. The support includes porous silica particles having an interparticle void structure therein, characterized in that the porous silica particles have a specific average particle size, a specific surface area, a specific pore volume, a specific pore size distribution and a specific porosity and have a substituent containing an organic group or an amino group on the surface thereof. An immobilized protein obtained by immobilizing a protein on the above support is also described.

    摘要: The purpose of the present invention is to provide a simple and economical method for the production of BC having improved properties such as dispesibility, suspensibility and viscosity.The present invention relates to a method for the improvement of dispersibility and suspensibility of bacterial cellulose, comprising concentrating an aqueous suspension of bacterial cellulose to a final concentration of the bacterial cellulose of between 10% by weight or more and less than 75% by weight, dispersing it again into an aqueous solution and homogenizing the bacterial cellulose in the resulting dispersion, to a method for the improvement of paper properties of bacterial cellulose, comprising concentrating an aqueous suspension of homogenized bacterial cellulose to a final concentration of the bacterial cellulose of between 4% by weight or more and less than 75% by weight, dispersing it again into an aqueous solution and homogenizing the bacterial cellulose in the resulting dispersion, and to the BC concentrate thus prepared.
