Isolating Tryptophan Regulatory Mutants in Escherichia coli by Using a trp-lac Fusion Strain
A trp-lac fusion strain of Escherichia coli in which the lac structural genes are part of the tryptophan operon has been used to isolate trp regulatory mutants. This was accomplished by isolating lac(+) colonies on either lactose-minimal agar or lactose-MacConkey indicator agar. Seventy-seven of 78...
