Abstract:
A process to produce straight or branched carbohydrate polymers comprising:a) transferring a monosaccharide or oligosaccharide residue from a carbohydrate donor to an acceptor by using an enzyme, thereby forming a reaction mixture containing by-products which inhibit the activity or selectivity of the enzyme and carbohydrate polymers; b) removing any by-products from the reaction mixture formed in step a) which may inhibit yield or selectivity of the enzyme; c) separating carbohydrate polymers which have not achieved the desired chain length from carbohydrate polymers which have achieved the desired chain length; and d) recycling the carbohydrate polymers which have not achieved the desired chain length to said transferring step.
