Abstract
The heat generated by biodegradation in landfill site led to an increase in landfill temperature. This phenomenon considered to be a consequence of the heat generated by the biodegradation process. The increasing temperature is one of the stress factors for the bacteria in the landfill site. This factor will interfere with the cell’s metabolism and suppress the bacteria to grow. The focus of this study is to look into the influence of temperature on the adsorption ofEscherichia coli(E. coli) from landfill leachate using a geosorbent. The geosorbent was made from Dredged Marine Soils (DMS). The application of geosorbent as landfill liner could potentially entrap and reduce the pathogenic bacteria in leachate. Least number ofE. coliwas found in the landfill leachate at high-temperature degree. Concurrently a high number ofE. coliwas counted in the geosorbent. Findings from this study supported the idea thatE. coligrowth in landfill leachate was suppressed by the increment of the temperature. As a result,E. colideveloped strategies to respond against this environmental stress. TheE. colishifted from landfill leachate to the geosorbent seeking for protection. In general, the geosorbent using DMS material demonstrated the ability to adsorb bacteria at varied temperature degree.
