Abstrakt:

Experimental investigations of biotransformation of mercury Hg(II) to Hg(0) in aqueous solution by immobilized bacteria were carried out in two types of lab scale bioreactors: in fixed andfluidized bed. An isolated and identified natural strain of Aeromonas hydrophila was immobilizedon the surfaces of porous carriers and employed in mercury removal from liquid phase in thefixed bed reactor. For mercury biotransformation in the fluidized bed a genetically modifiedstrain of Pseudomonas putida KT2442:; mer73 entraped in PVA gel beads was used. The investigations reveal that mereuiy biotransformation is a fast process controlled by diffusion. Themost promising way of mercury removal from waste-water is employment of fluidized bed ofimmobilized bacteria, because of continuous mercury volatilization and possible recovery of thismetal.
