    摘要: The invention relates to a method for producing polysaccharides containing &agr;-1,4-glucan chains. According to the inventive method, a glucosyl group acceptor undergoes a chain prolongation reaction by reacting it with saccharose in the presence of an amylosaccharase. The amount of the glucosyl group acceptor in the reaction mixture is chosen in such a way that the mole ratio of the available ends of the glucosyl group acceptor to the saccharose is at least 1:1,000 and/or the weight ratio of the glucosyl group acceptor to the saccharose is at least 1:0.
