Abstract: A method for producing a hollow fiber film, characterized in that a poly(vinylidene fluoride) type resin solution which comprises a poly(vinylidene fluoride) type resin and a poor solvent for the resin and ha s a temperature of the phase separation temperature thereof or higher is delivered into a cooling bath having a temperature of the phase separation temperature or lower, to thereby coagulate the resin; and a hollow fiber fil m, characterized in that it comprises a poly(vinylidene fluoride) type resin an d has a spherical structure having an average diameter ranging 0.3 to 30 .mu.m . The method allows the production of a hollow fiber film of a poly(vinylidene fluoride) type resin having high chemical resistance, which exhibits high strength and high water permeability, at a low load to the environment and a t a low production cost.

Abstract: The invention provides a method of producing a chemical product through continuous fermentation which includes filtering a culture of a microorganism or cultured cells with a separation membrane to recover a product from a filtrate and simultaneously retaining a nonfiltered fluid in, or refluxing it to, the culture, and adding fermentation materials to the culture, wherein a porous membrane having an average pore size of 0.01 µm or more to less than 1 µm is used as the separation membrane and the filtration is conducted with a transmembrane pressure difference in the range of 0.1 to 20 kPa. According to this method, the fermentation productivity of the chemical product can be largely elevated at high stability and a low cost.
