Human health and the environment are endangered by heavy metal pollution in water and sediment. To battle this problem, a '''purification strategy''', in which arsenic, zinc and copper are removed from water and sediment, was developed. This strategy encompasses a biological device in which <i>E. coli</i> bacteria accumulate metal ions from solutions, after which they '''produce gas vesicles''' and '''start floating'''. This biological device consists of two integrated systems: one for metal uptake and storage, the other for metal induced buoyancy. The uptake and storage system consists of a [[Team:Groningen/Project/Transport|metal transporter]] and [[Team:Groningen/Project/Accumulation|metal binding proteins]] (to reduce toxicity and increase accumulation). The buoyancy system is made up of a [[Team:Groningen/Project/Promoters|metal induced promotor]] in front of a [[Team:Groningen/Project/Vesicle|gas vesicle gene cluster]]. The combination of both systems will enable the efficient cleaning of polluted water and sediment in a biological manner. | Human health and the environment are endangered by heavy metal pollution in water and sediment.

Heavy metal scavengersHuman health and the environment are endangered by heavy metal pollution in water and sediment. To battle this problem, a purification strategy, in which arsenic, zinc and copper are removed from water and sediment, was developed. This strategy encompasses a biological device in which E. coli bacteria accumulate metal ions from solutions, after which they produce gas vesicles and start floating. This biological device consists of two integrated systems: one for metal uptake and storage, the other for metal induced buoyancy. The uptake and storage system consists of a metal transporter and metal binding proteins (to reduce toxicity and increase accumulation). The buoyancy system is made up of a metal induced promotor in front of a gas vesicle gene cluster.
