Guanosine Formation from Guanine by Bacillus licheniformis

Abstract

Adenine-auxotrophic mutant of Bacillus licheniformis formed considerable amount of guanosine from guanine. The guanosine formation was stimulated by the addition of penicillin to the growing cells and by the presence of uridine in the crude extract. The crude extract preserved for long time showed the changes of the enzyme actions for added guanine.
