  • Title: Selective autocytotoxicity in a model system of Escherichia coli K-12 recombinants.
    Author: Martinez D, Whitehouse F.
    Journal: J Bacteriol; 1973 May; 114(2):882-4. PubMed ID: 4574705.
    Abstract:
    Autocytotoxicity was shown by Lac(+) recombinant strains of Escherichia coli K-12 when their growth was inhibited in media containing o-nitrophenyl-beta-d-galactopyranoside. Lac(-) strains without lactose permease or beta-galactosidase activity grew well. Selective autocytotoxicity was shown by simultaneous inhibition of Lac(+) cells and multiplication of Lac(-) cells grown together in this medium.
