| Summary: | Bioremediation is a technique that can be used to clean up the contaminated site or water. This method is advancement in biotechnology development of biological method in removal and contaminant degradation. By doing this research, we can study how it can solve the contaminated site and water problem. The main objective of this research is to study the potential microbe to remove cadmium by using bioremediation method and also to characterize the bacterial that exist from wastewater contained cadmium. The sources of contaminated water that contain cadmium was collected from wastewater plant located at Huntsman Tioxide (M) Sdn Bhd, Kemaman Terengganu Darul Iman. In this research, there will be a several methods used such as isolation, characterization and degradation of cadmium that can be used in bioremediation techniques. The isolated microbe from wastewater sample which is P1 is gram-negative bacterium and have cocci in shaped. It exhibited at the greatest cadmium tolerance. It was able to survive in 10mg/l of cadmium concentration. In culture exposed to 10mg/l, microbe P1 cells degrade 74.9% of cadmium in first day and decreased at second day to fifth day; 19.9%, 0.1%, 0.6% and 2.3% respectively. The highest amount of cadmium removed per ml of culture was observed in first day with 7.49 mg/l of cadmium. In conclusion, the microbe P1 has been shown the great potential of degrading the cadmium inside the wastewater. |
