Biodegradasi Limbah Lindi Hitam, Acid Orange dan Acid Red menggunakan Jamur Trametes versicolor F200
Abstract
Limbah lindi hitam dan zat warna azo (acid orangedan acid red) merupakan limbah berbahaya yang dapat mengkontaminasi ekosistem, sehingga perlu dilakukan pengolahan sebelum limbah dibuang ke ekosistem. Pengolahan secara fisik maupun kimiawi memiliki kelemahan diantaranya membutuhkan input energi tinggi, biaya yang mahal, penerapan yang terbatas dan menghasilkan produk lain yang bersifat toksik. Trametes versicolor dapat dijadikan sebagai agen biodegradasi, sebab menghasilkan anzim ligninolitik seperti Lakase (Lac), Manganese peroksidase (MnP) dan Lignin peroksidase (LiP).Jamur T. versicolor F200 mampu mendekolorisasi hingga 50%pada limbah lindi hitam; 90% pada Acid orange; dan 90% pada Acid red. Aktivitas enzim Lac, MnP dan LiP terbaik masing-masing yaitu 143,59 U/L (6 hari inkubasi), 33,3 U/L (6 hari inkubasi) dan 1167,42 U/L (awal inkubasi) pada limbah lindi hitam; 520,513 U/L) (awal inkubasi), 138 U/L (awal inkubasi) dan 358 U/L (awal inkubasi) pada acid orange; dan 408,3 U/L (awal inkubasi, 77 U/L (awal inkubasi) dan 228,871 U/L (akhir inkubasi).
