Heavy metal pollution of water and sediment endangers human health and the environment. To battle this problem, a purification strategy was developed in which arsenic, zinc or copper are removed from metal-polluted water and sediment. In this approach Escherichia coli bacteria accumulate metal ions from solutions, after which they produce gas vesicles and start floating. This biological device encompasses two integrated systems: one for metal accumulation, the other for metal-induced buoyancy. The uptake and storage system consists of a metal transporter and metallothioneins (metal binding proteins). The buoyancy system is made up of a metal-induced promoter upstream of a gas vesicle gene cluster. This device can be changed to scavenge for any compound by altering the accumulation and the induction modules. The combination of both systems enables the efficient decontamination of polluted water and sediment in a biological manner.

Heavy metal pollution of water and sediment endangers human health and the environment. To battle this problem, a purification strategy was developed in which arsenic, zinc or copper are removed from metal-polluted water and sediment. In this approach Escherichia coli bacteria accumulate metal ions from solutions, after which they produce gas vesicles and start floating. This biological device encompasses two integrated systems: one for metal accumulation, the other for metal-induced buoyancy. The uptake and storage system consists of a metal transporter and metallothioneins (metal binding proteins). The buoyancy system is made up of a metal-induced promoter upstream of a gas vesicle gene cluster. This device can be changed to scavenge for any compound by altering the accumulation and the induction modules. The combination of both systems enables the efficient decontamination of polluted water and sediment in a biological manner.
