Title:
ISOLATION OF MICROBIC POLYSACCHARIDE IN FORM OF AMINE ADDUCT
Document Type and Number:
Japanese Patent JPS5953501
Kind Code:
A
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. It is advantageous to add the amine to the polysaccharide solution and then to carry out the precipitation, in particular by adding the dispersion obtained to an acidic coagulation bath. The adducts are suitable for use as thickeners and for preparing the free polysaccharides.
