The bioremediation of emerging recalcitrant pollutants in wastewater via enzyme biotechnology has been evolving as cost-effective with an input of low-energy technological approach. However, the enzyme based bioremediation technology is still not fully developed at a commercial level. The oxidoreductases being the domineering biocatalysts are promising candidates for wastewater treatments. Henceforth, comprehending their global market and biotransformation efficacy is mandatory for establishing these techno-economic bio-enzymes in commercial scale. The biocatalytic strategy can be established as a combinatorial approach with existing treatment technology to achieve towering bioremediation and effective removal of emerging pollutants from wastewater. This review provides a novel insight on the toxicological xenobiotics released from industries such as paper and pulps, soap and detergents, pharmaceuticals, textiles, pesticides, explosives and aptitude of peroxidases, nitroreductase and cellobiose dehydrogenase in their bio-based treatment. Moreover, the review comprehensively covers environmental relevance of wastewater pollution and the critical challenges based on remediation achieved through biocatalysts for future prospectives.
通过酶生物技术对废水新兴难处理污染物进行生物修复，作为一种具有成本效益的低能源技术方法不断发展。然而，基于酶的生物修复技术在商业水平上仍未完全开发。氧化还原酶作为占主导地位的生物催化剂，是废水处理的有前途的候选物。因此，了解它们的全球市场和生物转化效果对于在商业规模上建立这些技术经济生物酶是强制性的。生物催化策略可以与现有处理技术相结合，建立组合方法，以实现卓越的生物修复和有效去除废水中的新兴污染物。
本综述提供了一个新颖的视角，探讨了造纸和纸浆、肥皂和洗涤剂、制药、纺织、农药、爆炸物等行业释放的毒理性外源性物质，以及过氧化物酶、硝基还原酶和纤维二糖脱氢酶在生物处理中的应用。此外，本综述还全面涵盖了废水污染的环境相关性以及基于生物催化剂修复的关键挑战，为未来的发展提供了展望。
