Cactaceae Nopalea cochenillifera cell cultures and intact plants (cladodes) transform various toxic textile dyes, including Red HE7B into less phytotoxic, non-hazardous metabolites. The [tentative] pathway analysis demonstrates that Red HE7B is transformed into 3-amino-5-imino-5,8-dihydronaphthalen-2-ol, 2-amino-6-(carboxycarbonyl)-3,4-dihydroxybenzoic acid, 4-aminophenol, and phenoL The significant induction of the activities of intracellular laccase (687%), tyrosinase (219%), azoreductase (144%), and 2,6-dichlorophenolindophenol reductase (167%) indicated the involvement of these enzymes in the transformation pathways of Red HE7B but these enzymes have not been definitively linked to the phytotransformation of this toxic dye. The present foundation work could add another plant candidate for phytoremediation of undesirable products from industry wastes and harmful chemicals.
仙人掌科诺帕利拉 cochenillifera 细胞培养物和完整植物(刺)转化各种有毒纺织染料,包括红色 HE7B 为毒性较低、无危险的代谢物。[暂定]途径分析表明,红色 HE7B 转化为 3-氨基-5-亚氨基-5,8-二氢萘-2-醇、2-氨基-6-(羧基羰基)-3,4-二羟基苯甲酸、4-氨基酚和苯酚。细胞内漆酶(687%)、酪氨酸酶(219%)、偶氮还原酶(144%)和 2,6-二氯苯酚靛酚还原酶(167%)的活性显著诱导表明这些酶参与了红色 HE7B 的转化途径,但这些酶尚未明确与该有毒染料的植物转化相关。目前的基础工作可以为植物修复工业废物和有害化学品产生的不良产物再添加一个候选植物。
