Abstract
Bifunctional oligosaccharides, characterized by the formula ##STR1## wherein R.sub.1 represents a hydrogen atom, an alkyl group having 1-4 carbon atoms or an alkali metal, R.sub.2 represents a single bond or a divalent radical compound of monosaccharides and glc represents glucose, are obtained with the help of a specific microbial lyase cleaving the glucose-glucoronic acid bond in polysaccharides; said bifunctional oligosaccharides can be reacted with all kinds of products like proteins and drugs resulting in products having modified properties like solubility etc.
