Abstract: Polysaccharides are obtained by fermentation using a mixed culture of several microorganisms, of which at least one also produces a polysaccharide in pure culture, which polysaccharides are suitable as viscosity regulators. A mixed culture of the strains Pseudomonas maltophilia DSM 2130 and Agrobacterium tumefaciens DSM 2128 is particularly suitable.

Abstract: A process for the single-stage preparation of glycosyl fluorides by dissolving saccharides in liquid hydrogen fluoride and evaporating the hydrogen fluoride, wherein the resulting glycosyl fluoride is isolated in such a way that, when the evaporation of the hydrogen fluoride is started at a relatively high temperature, in general at -20 DEG to +20 DEG C., the evaporation is effected at a high evaporation rate or, when a low evaporation rate is used at the start of the evaporation, a sufficiently low temperature is set, in general -80 DEG C. to -30 DEG C.
