title: A novel biosensor selective for organoarsenicals.
abstract: Organoarsenicals used as herbicides and growth promoters for farm animals are degraded to inorganic arsenic. Available bacterial whole-cell biosensors detect only inorganic arsenic. We report a biosensor selective for the trivalent organoarsenicals methylarsenite and phenylarsenite over inorganic arsenite. This sensor may be useful for detecting degradation of arsenic-containing herbicides and growth promoters.
