“…The effects of antibiotics on ecological functions may cause changes in nitrogen transformation, methanogenesis, sulfate reduction, nutrient cycling, and degradation of organic matter, causing an ecological imbalance [ 13 ]. In addition, exposure to antibiotics may also negatively impact non-target aquatic organisms, including freshwater algae [ 15 ], zooplankton [ 16 ], crustaceans, and fishes [ 17 ], by inducing chronic effects such as changes in behavior, reproduction, and growth [ 11 , 18 ].…”

Laccases are industrially relevant enzymes that have gained great biotechnological importance. To date, most are of fungal and mesophilic origin; however, enzymes from extremophiles possess an even greater potential to withstand industrial conditions. In this study, we evaluate the potential of a recombinant spore-coat laccase from the thermoalkaliphilic bacterium Bacillus sp. FNT (FNTL) to biodegrade antibiotics from the tetracycline, β-lactams, and fluoroquinolone families. This extremozyme was previously characterized as being thermostable and highly active in a wide range of temperatures (20–90 °C) and very versatile towards several structurally different substrates, including recalcitrant environmental pollutants such as PAHs and synthetic dyes. First, molecular docking analyses were employed for initial ligand affinity screening in the modeled active site of FNTL. Then, the in silico findings were experimentally tested with four highly consumed antibiotics, representatives of each family: tetracycline, oxytetracycline, amoxicillin, and ciprofloxacin. HPLC results indicate that FNTL with help of the natural redox mediator acetosyringone, can efficiently biodegrade 91, 90, and 82% of tetracycline (0.5 mg mL−1) in 24 h at 40, 30, and 20 °C, respectively, with no apparent ecotoxicity of the products on E. coli and B. subtilis. These results complement our previous studies, highlighting the potential of this extremozyme for application in wastewater bioremediation.

“…In the food web, molluscs behave as herbivores, predators, detritus (deposit or pedal feeding), and filter feeders [3]. They consume nutrients from bacteria, microzooplankton, mesozooplankton, and resuspended benthic microalgae [4,5]. In the global mollusc's diversity, 0.2 million species were recorded [6].…”

West Bengal-Odisha coastal mangrove ecosystem represent a productive and dynamic ecosystem enriched with diversified habitat and niches. The intertidal bivalve Glauconome chinensis has been reported presently in the intertidal zone of Subarnarekha estuary of West Bengal-Odisha coast of Bay of Bengal. The studied bivalve characterised by unique morphological and microanatomical features. The present paper deals with morphological (shape and sizes of the shell, siphon, mantle, foot, adductor muscle, gill, digestive gland, reproductive system) and also microanatomical characteristics of different body tissues of the intertidal bivalve Glauconome chinensis.

Glyphosate (GLY), the most widely used herbicide active ingredient (AI) in the world, is frequently detected in aquatic environments where it can affect non-target organisms. Globally, more than 2000 commercial GLY-based herbicides (GBHs) are used to control weeds. Non-target organisms are exposed to complex pesticide formulations under real environmental conditions, but the co-formulants contained in GBHs are classified as so-called inert and inactive ingredients in terms of their biological effects. The main objective of this comprehensive review is to compile the results of aquatic ecotoxicological studies on the side-effects of GLY, GBHs, and their formulating agents. Based on the results demonstrated for a variety of plant and animal aquatic organisms, oxidative stress appears to be a major trigger for these adverse effects, affecting the integrity of DNA and other biochemical functions. Furthermore, there is evidence of impairment of various physiological and behavioral functions. Adverse effects of GLY and GBHs have been observed even at very low concentrations. There are also differences in the sensitivity of the aquatic organisms tested, even with similar lifestyles, habitats or identical taxa. The studies typically investigate the short-term effects of a single exposure to GLY/GBH on a single species, whilst in reality multiple applications of GBHs together with other pesticides are common during a cropping cycle. Moreover, the interactions between GLY/GBHs and other aquatic contaminants are rarely studied. Higher toxicity of GBHs compared to GLY alone has often been observed, demonstrating that co-formulants can be highly toxic on their own and markedly increase the toxicity of the GBH formulation. The possible impurities in GBHs, such as heavy metals, can cause additional problems for the environment and food safety. The widespread and massive use of GBHs leads to increased exposure and environmental hazards. In addition, the need for a revision of the risk assessment system is emphasized. According to the results of aquatic ecotoxicological studies, the current use and pollution of the aquatic environment by GLY/GBHs is highly problematic and cannot be considered environmentally sustainable. It is, therefore, necessary to at least tighten the permitted forms of use.
