摘要

The unwieldiness of Fenton reaction on biodegradation of methyl orange (MO) by brown-rot fungus Gloeophyllum trabeum was investigated based on Fe2+-dependent reaction. The degradation of MO (final concentration 75 mg/L) was performed in mineral salt media with and without Fe~(2+) with incubation period at 0, 7, 14, 21, and 28 days. Degradation analysis was performed using UV-Vis Spectrophotometer and LC-TOF/MS. The highest MO degradation occurred during 28 days incubation, which approximately 46.67% and 38.89% in medium with and without Fe~(2+), respectively, indicated that the presence of Fe~(2+) enhanced MO degradation. C_(15)H_(18)N_3O_5S~- and C_(17)H_(22)N_3O_7S~- were the metabolic products of MO degradation in mineral salt medium with Fe~(2+). The MO pathway by G. trabeum was stated by termination on double bond of the azo group and followed by hydroxylation to C_(15)H_(18)N_3O_5S~-, and then undergoes methylation to C_(17)H_(22)N_3O_7S~-. This study assumed that Fenton reaction might be involved in MO biodegradation by G. trabeum.
