A method of producing a chemical product via continuous fermentation, which comprises filtering a liquid culture medium of a microorganism or cultured cells through a separation membrane, collecting the product from the filtrate, keeping the unfiltered liquid in the liquid culture medium or refluxing thereinto and additionally supplying the material to be fermented into the liquid culture medium, wherein a porous membrane having an average pore size of 0.01 µm or more but less than 1 µm is employed as the separation membrane and the filtration is carried out at an intermembrane pressure difference of from 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.

La présente invention concerne un procédé de production d'un produit chimique par fermentation continue, ledit procédé comprenant la filtration d'un milieu liquide de culture d'un microorganisme ou de cellules cultivées à travers une membrane de séparation, la collecte du produit à partir du filtrat, en laissant le liquide non filtré dans le milieu de culture liquide ou en l'y renvoyant, et de plus l'introduction des matières à faire fermenter dans le milieu de culture liquide. Une membrane poreuse dont les pores ont un diamètre moyen supérieur ou égal à 0,01 µm mais inférieur à 1 µm est utilisée en tant que membrane de séparation et la filtration est réalisée avec une différence de pression inter-membranaire comprise entre 0,1 et 20 kPa. Grâce à ce procédé, la productivité de la fermentation du produit chimique peut être fortement augmentée avec une stabilité élevée et un coût bas.
