Abstract

Telah dilakukan penelitian tentang biodegradasi pewarna tekstil metilen biru (MB) oleh Daedalea dickinsii dengan tujuan untuk mengetahui kemampuan D. dickinsii dalam mendegradasi MB. Degradasi dilakukan pada media cawan agar potato dextrose agar (PDA) dengan variasi konsentrasi MB 50, 75, dan 100 mg/L. D. dickinsii mampu mendegradasi MB pada media PDA dengan indeks dekolorisasi yaitu 0,92; 0,90; 0,88 pada konsentrasi MB secara berurutan 50, 75, dan 100 mg/L. Konsentrasi MB 100 mg/L dipilih untuk biodegradasi pada media cair potato dextrose borth (PDB). D. dickinsii mampu mendegradasi MB sebesar 21,20%; 24,64%; dan 53,55% setelah diinkubasi secara berurutan selama 0, 7, dan 14 hari. Dari proses degradasi MB oleh D. dickinsii selama 14 hari dihasilkan metabolit produk berupa C15H16N3S (3-(dimethylamino)-7- (methylamino)phenothiazine), C16H19N3SO (3,7- bis(dimethylamino)-4aH-phenothiazin-5-one) dan C16H21N3SO (4-(dimethylamino)-2-[m-(dimethylamino)phenylsulfinyl]benzen amine). Penelitian mengindikasikan bahwa D. dickinsii dapat digunakan untuk mendegradasi pewarna MB. ===================================================================================================== The biodegradation ability of Daedalea dickinsii to degrade methylene blue (MB) dye had been investigated. The degradation was done in potato dextrose agar (PDA) medium with addition of variation concentration of MB at 50, 75, and 100 mg/L. D. dickinsii had ability to degrade MB with decolourization index 0.92, 0.90, and 0.88 for concentration of MB at 50, 75, and 100 mg/L, respectively, in PDA medium. MB concentration at 100 mg/L was selected for biodegradation in liquid potato dextrose borth (PDB) medium. D. dickinsii degraded 21.20%, 24.64%, and 53.55% of MB after incubated for 0, 7, and 14 days. From14 days incubation, C15H16N3S (3-(dimethylamino)-7-(methylamino) phenothiazine), C16H19N3SO (3,7-bis(dimethylamino)-4aHphenothiazin- 5-one) and C16H21N3SO (4-(dimethylamino)-2-[m- (dimethylamino)phenylsulfinyl]benzen amine) were produced by D. Dickinsii as metabolite products of MB degradation. This study indicated that D. dickinsii can be used to degrade MB dye.
