Process for the preparation of exocellular biopolymers having a thickening effect in aqueous media by aerobic culture of microorganism strains forming the biopolymers in an aqueous nutrient medium present as disperse aqueous phase in a water/oil emulsion (W/O-emulsion) stable under fermentation conditions using W/O emulsifiers for emulsion formation and stabilization, in which the oil phase is used in quantities below 50% by volume, based on the mixture as a whole, and fatty acid dialkanolamides are used as the W/O emulsifiers.
