Abstract: Microbial polysaccharides can be quantitatively precipitated from their aqueous solutions, in particular directly from the fermentation solutions, in an acidic medium in the form of an adduct with a tertiary amine which has a long-chain alkyl radical.

The adducts are suitable for use as thickeners and for preparing the free polysaccharides.
