The purine metabolism of the 8-azaguanine resistant and 8-azaxanthine resistant strains of Leuconostoc mesenteroides P-60 were compared with that of the original strain. These resistant strains did not require preformed exogenous purines for their growth and were less sensitive to aminopterin and 6-mercaptopurine than the original strain. While the growth of the azaguanine-resistant strain was inhibited by 8-azaxanthine like the original strain, azaxanthine-resistant strain was not inhibited by 8-azaguanine.
