title: Uptake of nourseothricin by the producing microorganism, Streptomyces noursei.
abstract: The uptake of 14C-(U)-nourseothricin by stationary phase mycelium of Streptomyces noursei JA 3890 b-NG 13/14 was demonstrated. An energy-dependent transport system appears to be involved in the transport of the antibiotic. Relatively large quantities of the antibiotic were adsorbed to the surface of mycelium. Degradation of nourseothricin by the producing microorganism was not detectable.
