LAJU DEGRADASI SENYAWA HIDROKARBON YANG MENCEMARI TANAH OLEH Salipiger bermudensis (DQ 178660) DENGAN STIMULASI FERTILIZER

Salipiger bermudensis (DQ 178660) is one of soil bacterium that produce biosurfactant as a secondary metabolite. It was isolated and identificated for its capacity to utilize the fraction of hydrocarbons. The purpose of this research is to analyze degradation activity of Salipiger bermudensis (DQ 178660) on hydrocarbon contaminated soil. Salipiger bermudensis (DQ 178660)  was used as a model to degrade hydrocarbon and it was detected by GC-MS. Adding of fertilizer as a nutrient into soil is believed to enhanced in situ biodegradation by stimulating the growth of bacterium to degrade hydrocarbon contaminated soil. Analysis of Gas Chromatography – Mass Spectroscopy showed that degradation of hydrocarbon by Salipiger bermudensis (DQ 178660) has been successed respectively. It means that Salipiger bermudensis (DQ 178660) was be able to degrade hydrocarbon contaminated soil.
