Abstract
A method of determining the molecular mass composition of microbial ex opolysaccharides (EPS) by centrifuging them in a combined density grad ient created by NaCl and CsCl solutions and using the molecular mass o f dextranes as standards is developed. The process of determining the molecular mass distribution pattern of EPS is simplified and made cons iderably less time-consuming. This method allows the analysis of nativ e EPS with molecular masses ranging from 13 700 to 2 000 000.
