    • The present invention relates to a process for producing a useful substance, which includes feeding a liquid mixture formed of two liquid phases into a fixed bed-type reaction column packed with an immobilized enzyme, and performing a reaction while allowing the liquid mixture to flow in the same direction in a co-current manner, wherein the fixed bed-type reaction column has partition plates inserted in the longitudinal direction of the fixed bed-type reaction column so as to form a plurality of tube-shaped structures, wherein each tube-shaped structure has a lateral cross-section which is circular or polygonal in shape with at least a part being unclosed and has a representative length of 100 mm or less, wherein the immobilized enzyme is packed into the tube-shaped structures, and wherein the liquid mixture is fed into the tube-shaped structures.Even when a reaction column having a large column diameter is used in the reaction performed by feeding a liquid mixture formed of two liquid phases into a fixed bed-type reaction column packed with an immobilized enzyme, the flow of the whole reaction liquid inside the column can be made uniform, and the enzymatic activity can be effectively appeared. As a result, reactivity and productivity can be enhanced. Particularly, in the hydrolysis of oils and fats, the enzymatic activity can be effectively appeared, so that fatty acids can be effectively produced. Furthermore, the operability at the time of removing the immobilized enzyme packed in the reaction column is good.
    • 本发明涉及一种生产有用物质的方法,包括将由两个液相形成的液体混合物进料到装有固定化酶的固定床型反应塔中,并进行反应同时使液体混合物流入 相同的方向,其中固定床型反应塔具有沿固定床型反应塔的纵向方向插入的隔板,以形成多个管状结构, 所述圆形结构具有圆形或多边形的横截面,其至少一部分未封闭并且具有100mm或更小的代表性长度,其中所述固定化酶被包装在所述管状结构体中,并且其中所述液体 混合物被送入管状结构。 即使在通过将由两个液相形成的液体混合物进料到装有固定化酶的固定床型反应塔中进行的反应中使用具有大柱直径的反应塔时,柱内的整个反应液体的流动 可以均匀,可以有效地出现酶活性。 因此,可以提高反应性和生产率。 特别是在油脂的水解中,能够有效地发挥酶活性,能够有效地制造脂肪酸。 此外,除去反应塔中填充的固定化酶时的操作性良好。
