Abstract
By cultivating a D-ribose-producing microorganism of the genus Bacillus in a medium containing nutrients necessary for its growth, wherein the concentrations of L-tryptophan and L-tyrosine in the medium are controlled at 3 .mu.g/ml or less and 10 .mu.g/ml or less, respectively. D-ribose is produced in a good yield and the by-production of gluconic acid is efficiently suppressed.
Claims7
A process for producing D-ribose which consists essentially of cultivating a D-ribose-producing microorganism of the genus Bacillus in a medium containing nutrients necessary for its growth, wherein the concentrations of L-tryptophan and L-tyrosine in the medium are controlled at 3 .mu.g/ml or less and 10 .mu.g/ml or less, respectively, and harvesting the D-ribose produced and accumulated thereby from the medium.
