title: Ribostamycin, as an intermediate in the biosynthesis of neomycin.
abstract: A mutant of a neomycin-producting Streptomyces fradiae was found which synthesizes ribostamycin instead of neomycin. After a reverse mutation new colonies were obtained producting neomycin again. Ribostamycin might thus be considered as an intermediate in the biosynthesis of neomycin.
