Abstract

Process for the production of chemical materials by the submerged and aerified fermentation method of a microorganism, characterized by the operation of weakening and reducing the foam without appreciably reducing the proportion of dissolved oxygen in the fermentation broth at the same time, by adding it thereto , as a defoaming agent, of a water-soluble condensation product, of a total molecular weight of the order of about 1600 to 2800, of ethylenic oxide with a hydrophobic polyoxypropylene chain insoluble in water, formed by the condensation of propylene oxide with propylene glycol said hydrophobic chain having a molecular weight of the order of about 1500 to 2500 and constituting about 90% by weight of said water-soluble condensation product.
