Lichen is a self-supporting symbiotic association of fungi and algae which was not yet explored for its bioremediation potential. Lichen Permelia perlata showed potential of decolorization and biodegradation of Solvent Red 24 (SR24). Optimum pH and temperature for decolorization was found to be 8 and 50°C, respectively. Induction in the activity of laccase in P. perlata during biodegradation of SR24 showed their involvement. HPTLC, FTIR and GC-HRMS analysis confirmed biodegradation of SR24 in to metabolites such as naphthalen-1-yldiazene, naphthalene, 1-(2-methylphenyl)-2-phenyldiazene and diphenyldiazene. Phytotoxicity and genotoxicity analysis revealed the reduction in toxicity of SR24 after its biodegradation.
地衣是真菌和藻类共生的自养体，其生物修复潜力尚未得到探索。地衣 Permelia perlata 显示出对溶剂红 24（SR24）的脱色和生物降解潜力。发现最佳脱色 pH 值和温度分别为 8 和 50°C。在 SR24 的生物降解过程中，漆酶活性的诱导表明其参与了这一过程。HPTLC、FTIR 和 GC-HRMS 分析证实了 SR24 生物降解为萘-1-基二氮烯、萘、1-(2-甲基苯基)-2-苯基二氮烯和二苯二氮烯等代谢物。植物毒性和遗传毒性分析表明，SR24 生物降解后毒性降低。
