Abstract

Penelitian ini tentang biodegradasi pewarna tekstil metil orange (MO) oleh jamur pelapuk coklat Gloeophyllum trabeum dengan tujuan untuk mengetahui kemampuan G. trabeum dalam mendegradasi MO. Biodekolorisasi MO dilakukan pada media cawan agar potato dextrose agar (PDA) dengan variasi konsentrasi MO. G. trabeum mampu mendekolorisasi MO pada media cawan agar untuk konsentrasi 50, 75, dan 100 mg/L dengan masing–masing indeks dekolorisasi yaitu 0,75; 0,70 dan 0,56. Biodegradasi MO juga dilakukan pada media potato dextrose borth (PDB). G. trabeum mampu mendegradasi MO sebesar 4,94% , 41,57%, dan 47,53% setelah diinkubasi selama 0, 7 dan 14 hari. Dari proses degradasi MO oleh G. trabeum dihasilkan metabolik produk yaitu 4-{[(4-dimetilamin-3-hidroksi) fenil] diazeni} benzensulfonat, 4-{[fenilamin]diazenil} benzensulfonat, 4-{[(4-metilamin-3-hidroksi) fenil] diazenil} benzenoksi, 4-{[(3,5-dihidroksiamin) fenil] diazenil} benzensulfonat, dan Hydroquinone. Penelitian mengindikasikan bahwa G. trabeum dapat digunakan untuk mendegradasi MO. =========================================================================================== The biodegradation of methyl orange (MO) dye by brown rot fungus Gloeophyllum trabeum was investigated. Biodecolorization of MO was conducted on potato dextrose agar (PDA) medium with a variation concentration of MO. G. trabeum had ability to decolorize MO on PDA medium in concentration of 50, 75, and 100 mg/L with each decolorization index (DI) of 0.75; 0.70 and 0.56 respectively. Biodegradation of MO was also conducted on potato dextrose borth (PDB) medium. G. trabeum degraded MO by 4.94%, 41.57%, and 47.53% after incubated for 0, 7 and 14 days, respectively. Detected metabolic products were 4-{[(4-dimethylamin-3-hydroxy) phenyl] diazenil} benzensulfonate , 4-{[phenylamin] diazenil} benzensulfonate, 4- {[(4-methylamin-3-hydroxy) phenyl] diazenil} benzenoxy, 4- {[(3,5-dihydroxyamin) phenyl] diazenil} benzensulfonate, and Hydroquinone. This study indicated that G. trabeum can be used to degrade MO.
