A process for producing a sugar nucleotide characterized by using as an enzyme source an optionally processed culture of a microorganism capable of producing the sugar nucleotide from a nucleotide precursor and a sugar, effecting an enzymatic reaction in an aqueous medium containing the enzyme source, the nucleotide precursor and the sugar to thereby accumulate the sugar nucleotide in the medium, and taking up the sugar nucleotide from the medium; and a process for producing a complex carbohydrate characterized by using as enzyme sources an optionally processed culture of a microorganism capable of producing a sugar nucleotide from a nucleotide precursor and a sugar, and an optionally processed culture of a microorganism or animal cells capable of producing the complex carbohydrate from the sugar nucleotide and a complex carbohydrate precursor, effecting enzymatic reactions in an aqueous medium containing these enzyme sources, the nucleotide precursor, the sugar and the complex carbohydrate precursor to thereby accumulate the complex carbohydrate in the medium, and taking up the complex carbohydrate from the medium. |
