| Summary: | Phthalate compounds that are commonly found in everyday life are diethyl phthalate (DEP). This compound is dangerous because it is carcinogenic, xenoestrogenic and its effect on the endocrine disrupts the binding and action of natural hormones, thus disrupting physiological processes. The accumulation of plastic in the landfill causes this compound to be identified in leachate with an existing concentration of 1,277 mg/L. Biological treatment is one of the appropriate technologies in DEP removal. The treatment is carried out by removing DEP using fungi isolated in the leachate water sampled. The mechanism of phthalate degradation by fungi can be explained simply where fungi use phthalate as the only source of carbon and energy for their growth. Degradation tests were carried out at varying concentrations of 2 mg/l, 4 mg/l, 6 mg/l, 8 mg/l and 10 mg/l in a test time span of 15 days and analyzed every 3 days. Concentration testing was carried out by analysis using High Performance Liquid Chromatography (HPLC). DEP removal efficiency reached 98-99% in each concentration variation on day 9 with a specific fungal growth rate of 0.0531-0.111/day |
