Hollow Fiber Membrane Module For Use In Production Of Chemical Substance And Process For Production Of Chemical Substance

Abstract: A hollow fiber membrane module for use in production of a chemical substance, which is used in continuous fermentation including.filtering a fermentation broth of a microorganism or a cultured cell through a hollow fiber membrane, collecting a chemical substance from a filtrate, retaining a concentrated solution in the fermentation broth or refluxing the concentrated solution, and adding a fermentation raw material to the fermentation broth, wherein a large number of hollow fiber membrane bundles are accommodated in a tubular case, at least one end part of each of the hollow fiber membrane bundles is fixed on the tubular case by a hollow fiber membrane bundling member with an end face of each of the hollow fiber membranes open, and the hollow fiber membrane bundling member is made of a synthetic resin having a hardness retention rate after contact with saturated steam at 121°C for 24 hours of 95% or more. Therefore, a hollow fiber membrane module for use in the production of a chemical substance by a continuous fermentation process capable of maintaining high productivity and treating steam sterilization is provided.
