Abstract
Extensive use of detergent in households and massive disposal of the waste directly into the environment causes pollution of aquatic environment. Bioremediation is one of the effort taken to overcome this problem. In this study, fourlocal bacterial isolates were successfully obtained which were able to degrade SDS about 88%. Furthermore, optimization of SDS biodegradation was carried out using four consortiums from the mixed four isolates. The biodegradation ability of SDS was analyzed using the AS-MB method with double repetitions. Based on the SDS degradation capability by four consortia (A, B, C and D), two consortiums (B and C) showed the ability to degrade SDS 96.4% and 98.3%, respectively. The main capabilities of the B and C consortium were played mainly by isolates SB-2-1 and SB-3-3. The application of the two best consortiums for liquid waste containing-detergent showed that both of them were able to reduce surfactant concentrations by 33.2% and 37.3% in 6 days, better than compared with the natural biodegradation without bacterial isolates which were only able to degrade 5%.
