Induction of the cadBA operon under acidic conditions and in the presence of lycine neutralized extracellualr environment and enabled production of CO(2); production of cadaverine and aminopropylcadaverine instead of putrescine and spermidine also resulted. cadAB operon induction also generates a proton motive force. Lack of cadBA opereon induction results in an increase in speF-potE operon expression.
