title: Simultaneous selection of mutants in gluconeogenesis and nucleoside catabolism in Salmonella typhimurium.
abstract: Penicillin selection in minimal thymidine medium, used to select mutants in deoxynucleoside catabolism, also yields a high percentage (37%) of mutants in fructose diphosphatase. The expression of the deo regulon is retarded in the mutants defective in the glyconeogenic pathway.
