Procedure for Isolating Mutants Defective in Metabolite Transport or Utilization

Claire M Berg 1, John J Rossi 1, Joyce V Coleman 1, Michele Conlon 1
PMCID: PMC246058  PMID: 1090600

Abstract

Mutants defective in uptake or utilization of a given metabolite can readily be obtained from facultative auxotrophs (for that metabolite) by penicillin enrichment under nonpermissive conditions in the presence of a low level of the required metabolite.
