摘要

全球每年都会产生大量有机污染物,这些污染物通常具有持久性和毒性,对土壤、水、地下水和空气构成威胁。污染物的来源多种多样,既有固态物质,也有液态物质,如垃圾填埋场沥滤液和废水。这些化合物包括造纸和纸浆厂副产品、药品、各种类型的塑料、碳氢化合物、颜料和染料,以及杀虫剂和杀虫剂。真菌生物修复技术利用真菌的新陈代谢潜力消除或减轻污染物的影响,是一项前景广阔的技术。值得注意的是,Pycnoporus 属的物种具有降解多种有毒分子的强大能力。释放出的木质素分解酶(尤其是漆酶)和细胞色素 P450 单氧化酶系统相关的细胞酶促进了这种降解。漆酶由 Pycnoporus 属过度产生,因其氧化还原电位高而引人注目。本综述旨在强调 Pycnoporus 属在沉水发酵和固态发酵中降解污染物的能力。在过去十年中进行的最新研究一致强调 Pycnoporus 属是白色生物技术领域的有力竞争者。

Biotransformation of Pollutants by Pycnoporus spp. in Submerged and Solid-State Fermentation: Mechanisms, Achievements, and Perspectives
Substantial amounts of organo-pollutants, often persistent and toxic, are generated globally each year, posing a threat to soil, water, groundwater, and air. The pollutants encompass a wide range of substances from various sources, which include solid as well as liquid ones, such as landfill leachates and wastewaters. The compounds include paper and pulp mill byproducts, pharmaceuticals, diverse types of plastics, hydrocarbons, pigments, and dyes, as well as pesticides and insecticides. Fungal bioremediation stands out as a promising technology that uses the metabolic potential of fungi to eliminate or mitigate the impact of pollutants. Notably, species of the genus Pycnoporus exhibit significant capabilities for degrading a broad spectrum of toxic molecules. This degradation is facilitated by released ligninolytic enzymes, especially laccase, and cellular enzymes pertaining to the cytochrome P450 monooxygenase system. The laccase, which is overproduced by the genus Pycnoporus, is quite remarkable for its high redox potential. The objective of this review is to highlight the proficiency of the Pycnoporus genus in the degradation of pollutants in submerged and solid-state fermentation. Recent studies conducted over the past decade consistently highlight the Pycnoporus genus as a robust contender in the realm of white biotechnology.
