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.
