“…ARS is a synthetic anthraquinonic acid–base indicator [ 35 , 36 ], used in histology to stain and locate calcium deposits in tissues [ 37 ], in geology to identify carbonate minerals, and widely used in textile dyeing. MG is a toxic and carcinogenic triphenylmethane dye, and is widely used in the textile and food industries, as well as in aquaculture as an antifungal, antimicrobial, and antiparasitic agent [ 38 , 39 , 40 , 41 ]. The synthesized MOF was characterized by means of XRD (X-ray diffraction), N 2 -adsorption isotherms, SEM (Scanning Electro Microscopy), FTIR (Fourier-Transform Infrared Spectroscopy), TGA (Thermogravimetric Analysis), and ELS (Electrophoretic Light Scattering) techniques.…”

Synthetic organic dyes are widely used in various industrial sectors but are also among the most harmful water pollutants. In the last decade, significant efforts have been made to develop improved materials for the removal of dyes from water, in particular, on nanostructured adsorbent materials. Metal organic frameworks (MOFs) are an attractive class of hybrid nanostructured materials with an extremely wide range of applications including adsorption. In the present work, an iron-based Fe-BTC MOF, prepared according to a rapid, aqueous-based procedure, was used as an adsorbent for the removal of alizarin red S (ARS) and malachite green (MG) dyes from water. The synthesized material was characterized in detail, while the adsorption of the dyes was monitored by UV-Vis spectroscopy. An optimal adsorption pH of 4, likely due to the establishment of favorable interactions between dyes and Fe-BTC, was found. At this pH and at a temperature of 298 K, adsorption equilibrium was reached in less than 30 min following a pseudo-second order kinetics, with k″ of 4.29 × 10−3 and 3.98 × 10−2 g∙mg−1 min−1 for ARS and MG, respectively. The adsorption isotherm followed the Langmuir model with maximal adsorption capacities of 80 mg∙g−1 (ARS) and 177 mg∙g−1 (MG), and KL of 9.30·103 L∙mg−1 (ARS) and 51.56·103 L∙mg−1 (MG).

“…Regarding MG, 92% decolorization was reached after 5 h of incubation in the presence of PhCOOH (Fig 7b). This result is of remarkable importance since MG is not only used as a dye for silk, leather, and paper, but also as a parasiticide and antifungal agent in aquaculture (Hashimoto et al, 2011).…”

“…Finding efficient methods for removal of these dyes is of main importance since reductive biotransformation of azo dyes results in the formation of toxic amines, while the anthraquinone dyes are resistant to degradation due to their fused aromatic ring structure (Ghaly et al 2014;Shing et al, 2015a). Additionally, oxidation of MG could prevent its metabolic reduction to leucomalachite, an equally carcinogenic form but with greater persistence in fish tissues (Hashimoto et al, 2011;Srivastava et al, 2014).…”

Laccases are oxidoreductases with the outstanding ability to oxidize phenolic and non-phenolic substrates coupled to the reduction of O2 to H2O. Among them, bacterial enzymes are suitable biocatalysts for application in industrial processes under harsh conditions. However, to be active on high redox potential substrates, bacterial laccases requires of redox mediators: electron carriers between the laccase and other compounds not directly oxidizable by the enzyme. Here we demonstrate that β-(10-phenothiazyl)-propionic acid can be used as an efficient and low-cost redox mediator for decolorization of synthetic dyes by bacterial laccases. Using this laccase-mediator system, more than 80% of Indigo Carmine and Malachite Green decolorization was reached after 1 h or 2 h of incubation, respectively, both at pH 8 and in tap water (pH 6.8). Furthermore, more than 40% of Remazol Brilliant Blue R and 80% of Xylidine ponceau were decolorized after 5 h at pH 8 and 50°C. In addition, we showed this system supports at least 3 decoloration cycles without loss of activity, representing a promising biological process for cost-effective and environmentally friendly decolorization and degradation of synthetic dyes and for other industrial applications of laccases requiring neutral or alkaline pH.

“…However, there are currently only 3 veterinary drugs regulated for use in aquaculture: florfenicol, oxytetracycline, and a parasiticide based on trichlorfon. Due to the lack of alternative veterinary medicinal products prescribed for use in aquaculture and the high cost of the available drugs, there is the suspicion that fish farmers are resorting to the irregular use of veterinary drugs prescribed for other animal species and even the use of illicit substances, such as the malachite green dye (FAO ; Hashimoto and others , ; MPA ).…”

Aquaculture has become an important source of fish available for human consumption. In order to achieve greater productivity, intensive fish cultivation systems are employed, which can cause greater susceptibility to diseases caused by viruses, bacteria, fungi, and parasites. Antimicrobial substances are compounds used in livestock production with the objectives of inhibiting the growth of microorganisms and treatment or prevention of diseases. It is well recognized that the issues of antimicrobial use in food animals are of global concern about its impact on food safety. This paper present an overview of the aquaculture production in the whole world, raising the particularities in Brazil, highlighting the importance of the use of veterinary drugs in this system of animal food production, and address the potential risks arising from their indiscriminate use and their impacts on aquaculture production as they affect human health and the environment. The manuscript also discusses the analytical methods commonly used in the determination of veterinary drug residues in fish, with special issue for fluroquinolones residues and with emphasis on employment of LC-MS/MS analytical technique.
