The present work provides a review focusing on contaminants of emerging concern (CECs) in aquatic environment, with an emphasis on their occurrence, monitoring, fate, and risk assessment in the research published in the scientific literature in 2019. Several studies revealed that these organic contaminants were detected in many water bodies and suspect, nontarget, and target screening provided an efficient detection for the co-existing organic substances with complex components. Wastewater resource recovery facilities were concurrently considered as a central source, and several specific chemicals have been found to be used as chemical markers to track the source of CECs in some urban watersheds. Reliable monitoring, reliable fate/toxicity assessment, and effective removal that consider CECs as a heterogeneous group rather than single substances will be the challenges for the research community in the future.

“…For this reason, their elimination from the environment is of paramount importance. Anti‐inflammatory drugs, antiepileptic and antidepressants are present in high concentration in wastewater and are challenging to be removed completely due to their physicochemical properties and resistance towards biological attack . Laccase enzymes can catalyze oxidation–reduction reactions to efficiently biodegrade some of these contaminants in a very efficient way and have been widely studied to improve the biodegradation of pharmaceutical contaminants (Table ) .…”

The application of enzymes offers an enormous potential in the improvement of existing industrial procedures and in the establishment of new processes for obtaining high-added value products. Enzymes provide cleaner and more efficient industrial processes and contribute to the sustainability concept. In this sense, laccases are very versatile biocatalysts currently used in food, textile and pulp and paper sectors among others. During the last years, scientific efforts have been diverted to the exploitation of such interesting enzymes in novel fields like lignocellulosic biorefineries, biosensors or enzymatic biofuel cells. This review provides a general vision of the use of laccase enzymes describing their main characteristics and mode of action. Furthermore, their current uses in industrial processes are summarized and the most novel potential application of laccases are revealed. The increasing interest on laccases is also demonstrated by the research efforts on enzyme engineering as it is detailed in this review. wileyonlinelibrary.com/jctb www.soci.org AD Moreno et al.

“…CECs usually reach aquatic compartments via domestic and industrial sewage or agriculture runoffs (Lapworth et al, 2012), where they are detected within nano (ng.L -1 ) or micro (µg.L -1 ) scales (Wilkinson et al, 2017) and frequently associated with a variety of short and long-term detrimental effects over biodiversity, community structure and human health (Brühl and Zaller, 2019;Lapworth et al, 2012;Saaristo et al, 2018;Sanchez and Egea, 2018;Santangeli et al, 2019). Because of the general inefficiently of conventional water treatment systems in the removal of such potutants (Bolong et al, 2009), the development of novel efficient and cost-effective technologies able to detect and/or remove the great diversity CECs from natural systems is greatly desirable (Bilal et al, 2019).…”

New tyrosinases with a broad spectrum of action against contaminants of emerging concern: Insights fromin silicoanalyses

Tyrosinases (EC 1.14.18.1) are type-3 copper metalloenzymes with strong oxidative capacities and low allosteric selectivity to phenolic and non-phenolic aromatic compounds that have been used as biosensors and biocatalysts to mitigate the impacts of environmental contaminants over aquatic ecosystems. However, the widespread use of these polyphenol oxidases is limited by elevated production costs and restricted knowledge on their spectrum of action. Here, six tyrosinase homologs were identified and characterized from the genomes of 4 widespread freshwater ciliates using bioinformatics. Binding energies between 3D models of these homologs and ~1000 contaminants of emerging concern (CECs), including fine chemicals, pharmaceuticals, personal care products, illicit drugs, natural toxins, and pesticides were estimated through virtual screening, suggesting their spectrum of action and potential uses in environmental biotechnology might be considerably broader than previously thought. Moreover, considering that many ciliates, including those caring tyrosinase genes within their genomes are fast-growing unicellular microeukaryotes that can be efficiently culturable at large-scales under in vitro conditions, should be regarded as potential low-cost sources for the production of relevant biotechnological molecules.
