    摘要: An industrially advantageous process for producing a substance wherein the production speed of a reaction product in a reaction with the use of a microbial catalyst can be maintained at a constant level over a long period of time. In a reaction with the use of a microbial catalyst (for example, resting cells of an arthrobacter capable of converting a-hydroxynitriles into the corresponding alpha -hydroxy acid amides or alpha -hydroxy acid ammonium salts), the substance is produced at a constant speed by adding the substrate at a constant speed, regulating the concentration of the microbial catalyst in the liquid reaction mixture at a constant level and controlling the temperature so as to rise the reaction temperature at the point that the enzymatic activity of the microbial catalyst is lowered in the course of the reaction so as to maintain the reaction speed at a constant level.

    摘要: A process for producing an amide compound from a nitrile compound by using a microbial catalyst characterized in that microbial cells having a nitrile hydratase activity of at least 50 U/mg dry cells at a reaction temperature of 10 DEG C, which are not in comprehensively immobilized, are brought into contact with a nitrile compound in an aqueous medium. According to this process in which microbial cells overexpressing the nitrile hydratase activity are used without comprehensive immobilization, the amide compound can be efficiently produced from the nitrile compound without causing the problem of lowering in the reaction speed or a decrease in the productivity per unit amount of the microbial cells due to the comprehensive immobilization. Accordingly, the amide compound can be produced within an extremely short period of time in case of a batch reaction, or by using equipment on a very small scale in case of a continuous reaction.
