Abstract
Hypoxanthine, inosine and/or inosine-51-monophosphate are produced by cultivating an adenine-requiring auxotroph of a microorganism in a medium containing a growth-limiting amount of adenine and substantially large amounts of other nutrient sources than are required for propagation of said auxotroph, and continuing cultivation after growth has substantially ceased in order to accumulate the desired products. In a modification, the auxotroph is grown in a complete medium and the resulting cells cultivated in a medium containing substantially no adenine as a non-proliferating cell suspension. The products may be recovered from the cells or the culture medium. Examples describe the use of auxotrophs of Bacillus subtilis, Saccharomyces cereviciae, Escherichia coli. Bacillus megatherium, Bacillus cereus, Torula utilis, Streptomyces fradiae, Penicillium citrinum and Aspergillus oryzae obtained by radiation induced mutation of the parent strains.
