Abstract

Due to environmental concern, the research to date has tended to focus on how textile dye removal can be carried out in a greener manner. Therefore, this study aims to evaluate the decolorization and biotransformation pathway of Mordant Orange-1 (MO-1) by Cylindrocephalum aurelium RY06 (C. aurelium RY06). Decolorization study was conducted in a batch experiment including the investigation of the effects of physio-chemical parameters. Enzymatic activity of C. aurelium RY06 during the decolorization was also investigated. Moreover, transformation and biodegradation of MO-1 by C. aurelium RY06 were observed using the gas chromatography-mass spectrometry. Manganese peroxidase, lignin peroxidase, laccase, 1,2-dioxygenase, and 2,3-dioxygenase enzymes were detected during the decolorization. In general, the present work concluded that the MO-1 was successfully degraded by C. aurelium RY06 and transformed to be maleic acid and to be isophtalic acid.

摘要

由于对环境的关注，迄今为止的研究往往侧重于如何以更环保的方式进行纺织品染料去除。因此，本研究旨在评估 Cylindrocephalum aurelium RY06（C. aurelium RY06）对媒染橙 1（MO-1）的脱色和生物转化途径。在分批实验中进行了脱色研究，包括对生理化学参数影响的研究。还研究了 C. aurelium RY06 在脱色过程中的酶活性。此外，还使用气相色谱-质谱法观察了 C. aurelium RY06 对 MO-1 的转化和生物降解。在脱色过程中检测到锰过氧化物酶、木质素过氧化物酶、漆酶、1,2-加氧酶和 2,3-加氧酶。总的来说，本工作得出结论，MO-1 被 C. aurelium RY06 成功降解，并转化为马来酸和间苯二甲酸。
