A mutant strain of Escherichia coli in which β‐glucoside transport is resistant to catabolite inhibition by methyl α‐glucoside was characterized. The mutation was probably within the gene, bglC , coding for the β‐glucoside enzyme II. The mutant organism is shown to transport the β‐glucoside substrate, salicin, in preference to methyl α‐glucoside or fructose. Salicin also caused inducer exclusion of lactose in the mutant strain.
