Biotransformasi Zat Warna Bromocresol Purple dengan Kultur Hidup dan Enzim La…

The purpose of this work is to ascertain how incubating a live culture and semipure laccase enzyme generated by a local isolate of Trichoderma asperellum LBKURCC1 from Riau, Indonesia, affects the biotransformation of the bromocresol purple (BCP) dye. Using a UV-Vis Spectrophotometer, absorbance of BCP was determined at 0, 3, 6, 9, and 24 hours at pH 5.2; 5.7, and 6.4 while the cultures were be…
