dc.description.abstractBacterial isolates from Carlsberg-Ridge waters were tested for their ability to immobilize Ni. For this, test cultures were suspended for 60 d in seawater with and without added Ni at concentrations of 10 to 10,000 mu M. At an initial concentration of 100 mu M, isolates CR35 and CR48 caused a 89.8 and 6.95 mu M decrease in dissolved Ni at 28 + or – 2 degrees C and a 14.75 and 6.38 mu M at 3 + or – 1 degree C. Analyses showed the contribution of hydroxyl, carbonyl, sulfide and phosphoryl groups in Ni binding. The study proves that Ni immobilization can occur even in the absence of Mn and suggests their plausible role in the ridge ecosystem.
