“…Oxidative stress parameters, such as the endogenous levels of antioxidants, were suggested as effective biomarkers of stress for multiple marine organisms, including corals (De Freitas Prazeres et al, 2012;Downs et al, 2005;Luz et al, 2018;Marangoni et al, 2017;Stuhr et al, 2017). Here, the increased TAC levels indicate that the corals are investing in antioxidant defences, a compensatory response to increasing thermal stress (Da Silva Fonseca et al, 2021;Marangoni et al, 2019;Marques et al, 2020). The steady increase likely reflects that the antioxidant capacity of the corals has not yet reached a tipping point, being overwhelmed by oxidative stress.…”

Antipatharians, also called black corals, are present in almost all oceans of the world, until extreme depths. In several regions, they aggregate in higher densities to form black coral beds that support diverse animal communities and create biodiversity hotspots. These recently discovered ecosystems are currently threatened by fishing activities and illegal harvesting for commercial purposes.

“…Numerous non-target organisms, such as bacteria, phytoplankton, invertebrates, fish, mammals, and humans, suffer from the deleterious effects of xenobiotics ( Giacomazzi and Cochet, 2004 ; Dupraz et al, 2016 ). As photosystem II and its conservation in plants are the targets of DUR, non-target phytoplankton is equally affected, such as seagrass and corals ( Marques et al, 2020 ; Thomas et al, 2020 ). Plants eventually die due to long-term starvation under moderate irradiation (electron transfer rate inhibition) or oxidative stress under higher levels of radiation ( Diepens et al, 2017 ; Wilkinson et al, 2017 ).…”

“… Negri et al (2015) reported 7-day IC 50 values (concentrations inhibiting quantum yield by 50%) of 2.7 and 3.8 μg/L for DUR on the growth of two tropical seagrass species, Zostera muelleri and Halodule uninervis , respectively. Moreover, phytoplankton could suffer from an additive toxicity effect with other adverse factors, such as ocean warming and ocean acidification ( Marques et al, 2020 ). van Dam et al (2015) conducted co-exposure experiments, revealing that the inhibition of photosynthetic yield under DUR and thermal stress is additive.…”

Emerging Strategies for the Bioremediation of the Phenylurea Herbicide Diuron

Diuron (DUR) is a phenylurea herbicide widely used for the effective control of most annual and perennial weeds in farming areas. The extensive use of DUR has led to its widespread presence in soil, sediment, and aquatic environments, which poses a threat to non-target crops, animals, humans, and ecosystems. Therefore, the removal of DUR from contaminated environments has been a hot topic for researchers in recent decades. Bioremediation seldom leaves harmful intermediate metabolites and is emerging as the most effective and eco-friendly strategy for removing DUR from the environment. Microorganisms, such as bacteria, fungi, and actinomycetes, can use DUR as their sole source of carbon. Some of them have been isolated, including organisms from the bacterial genera Arthrobacter, Bacillus, Vagococcus, Burkholderia, Micrococcus, Stenotrophomonas, and Pseudomonas and fungal genera Aspergillus, Pycnoporus, Pluteus, Trametes, Neurospora, Cunninghamella, and Mortierella. A number of studies have investigated the toxicity and fate of DUR, its degradation pathways and metabolites, and DUR-degrading hydrolases and related genes. However, few reviews have focused on the microbial degradation and biochemical mechanisms of DUR. The common microbial degradation pathway for DUR is via transformation to 3,4-dichloroaniline, which is then metabolized through two different metabolic pathways: dehalogenation and hydroxylation, the products of which are further degraded via cooperative metabolism. Microbial degradation hydrolases, including PuhA, PuhB, LibA, HylA, Phh, Mhh, and LahB, provide new knowledge about the underlying pathways governing DUR metabolism. The present review summarizes the state-of-the-art knowledge regarding (1) the environmental occurrence and toxicity of DUR, (2) newly isolated and identified DUR-degrading microbes and their enzymes/genes, and (3) the bioremediation of DUR in soil and water environments. This review further updates the recent knowledge on bioremediation strategies with a focus on the metabolic pathways and molecular mechanisms involved in the bioremediation of DUR.
