Abstract

The evaluation of continuous elimination and transformation of toxic endocrine disruptors micropollutants (MPs) (Bisphenol A, Nonylphenol [NP] and Triclosan [TCS]) using immobilized laccase of Coriolopsis sp. showed the high potential of this laccase as a bio-agent for the elimination and transformation process of selected MPs. A toxicology test using Escherichia coli has shown that toxicity completely disappeared after transformation and elimination of Bisphenol A, while in cases of NP and TCS 95% and 90% toxicity, respectively, disappeared. As compared to initial activity, immobilized laccase activity remained practically constant at the end of several runs of elimination and transformation processes of MPs. This feature is promising for the use of immobilized Coriolopsis sp. laccase in a future industrial depollution process.

固定化Coriolopsis sp.漆酶对酚类微污染物的持续消除和转化

利用固定化漆酶对有毒内分泌干扰物微污染物(双酚A、壬基酚[NP]和三氯生[TCS])的连续清除和转化评价表明，该漆酶作为一种生物制剂对所选的MPs进行清除和转化过程具有较高的潜力。利用大肠杆菌进行的毒理学试验表明，双酚A转化消除后毒性完全消失，而NP和TCS的毒性分别消失95%和90%。与初始活性相比，固定化漆酶的活性在MPs的消除和转化过程的几轮结束时几乎保持不变。这一特性为固定化科氏菌漆酶在未来工业除污过程中的应用提供了良好的前景。

期刊介绍： The Water Quality Research Journal publishes peer-reviewed, scholarly articles on the following general subject areas: Impact of current and emerging contaminants on aquatic ecosystems Aquatic ecology (ecohydrology and ecohydraulics, invasive species, biodiversity, and aquatic species at risk) Conservation and protection of aquatic environments Responsible resource development and water quality (mining, forestry, hydropower, oil and gas) Drinking water, wastewater and stormwater treatment technologies and strategies Impacts and solutions of diffuse pollution (urban and agricultural run-off) on water quality Industrial water quality Used water: Reuse and resource recovery Groundwater quality (management, remediation, fracking, legacy contaminants) Assessment of surface and subsurface water quality Regulations, economics, strategies and policies related to water quality Social science issues in relation to water quality Water quality in remote areas Water quality in cold climates The Water Quality Research Journal is a quarterly publication. It is a forum for original research dealing with the aquatic environment, and should report new and significant findings that advance the understanding of the field. Critical review articles are especially encouraged.
