Zagadenje zivotne okoline teskim metalima je ozbiljan problem savremenog sveta. Medumetalima koji su cesti zagadjivaci su: bakar, kadmijum i ziva. Cilj ovog rada je bilo ispitivanjeosetljivosti soja Pseudomonas aeruginosa san ai na pomenute teske metale. Minimale inhibitomekoncentracije kadmijuma i bakra od 2 i 4 mM, redom, pokazale su da je soj otporan na ova dvametala.MIK za zivu je bila najniza testirana koncentracija metala od 0,5 mM. Dobijene vrednostiMIK-aza kadmijum i bakar stavljaju soj P. aeruginosa san ai u grupu bakterija koje ispoljavajuvisokutoleranciju prema ovim teskim metalima. Utvrdeno je daje ziva toksicna za soj. lspitivanjamehanizama detoksikacije soja P. aeruginosa san ai u cilju potencijalne primene u procesimabioremedijacije su u toku.

Thepollution of the environment with toxic heavy metals is spreading throughout the world alongwithindustrial progress. Among the common heavy metals used and the more widespreadcontaminants of the environment are mercury, cadmium and copper. Present research wasperformedin order to screen tolerance of strain Pseudomonas aeruginosa san ai to these heavymetals.Study showed that P. aeruginosa san ai is tolerant to cadmum and coper with MIC's of 2and4 mM, respectively. MIC for mercury was the lowest tested concentration of 0.5 roM. Thissuggeststhat P. aeruginosa san ai has large potential for bioremediation of environmentscontaminatedwith cadmium and copper and that mercury is toxic for the strain. In order toimprovepossible application of strain P. aeruginosa san ai in processes of bioremediation thestudyofmechanisams of metal uptake are underway.
