Potensi Jamur dari Limbah Detergen dalam Mendegradasi Linear Alkylbenzene Sulfonate

Abstract

Contamination of detergent containing linear alkylbenzene sulfonate (LAS) waste could occur due to the absence of a standard system regarding waste management, especially from laundry businesses. This research aims to obtain fungal isolates from stream contaminated with detergent waste to degrade LAS. The parameters observed were the biosurfactant activity, the growth of isolates, and the residue of LAS.Isolation was carried out on selective Mineral Salt Medium (MSM) added with 150 ppm LAS as the carbon source. There were 9 fungal isolates that were able to produce biosurfactant. Screening of biosurfactant activity in the form of Emulsification Index (IE24), showed that 5 isolates showed the highest results, namely isolate SP 02 at 40.3%; SP 03 at 29.6%; SP 04 at 26.4%; SP 05 at 17.8%; SP 08 at 15%. The highest LAS degradation was in line with the best growth shown by isolate SP 02 at 85.80% and the best growth by isolate SP 02 at 0.73 g. While the lowest LAS degradation was found in isolate SP 08 at 47.45% with the lowest growth by isolate SP 08 at 0.33 g. Isolate SP 02 had the potential to degrade LAS surfactant and had the potential as a bioremediation agent.
