Abstract

1. Process for isolating microbial polysaccharides from adducts thereof with long-chain amines by treating these adducts with monohydric alkanols having 1 to 3 carbon atoms and with basic derivatives of alkali metals dissolved therein, which comprises using an adduct of a tertiary amine having one long-chain and two short-chain aliphatic radicals.
