Abstract
The purpose of this research was to investigate the potential of mercury resistant bacteria isolated from non-active solid waste landfill leachate. Biochemical characterization was used to identify the bacteria based on Bergeyââ¬â¢s Manual of Determinative Bacteriology. Biochemical analysis showed the potential bacteria was identified as Pseudomonas fluorescens with probability of 92.74%. Four concentrations of mercury, i.e. 5, 10,15 and 20/mg/L, were used for mercury resistance test. The IZD values at 0, 5, 10, 15, and 20 mg/L were 0.00ñ0.00, 0.7ñ0.03, 0.8ñ0.05, 1ñ0.08, and 1ñ0.05 cm, respectively. The MIC of mercury for P. fluorencens is 5mg/L. These results showed that P. fluorescens has a good potential to be used as bioremediation agent intreating mercury contaminated areas.
