ABSTRACT:
Uridine is produced by cultivating in a culture medium a uridine-producing microorganism, which belongs to the genus Bacillus and which is deficient in uridine nucleoside phosphorylase activity and is resistant to a pyrimidine analogue, and recovering the accumulated uridine. This method has the advantage of substantially avoiding the by-production of uracil and uridylic acid.
