“…On the other hand, Nouren et al [50] reported a better improvement in Zea mays seed germination, shoot and root length when exposed to treated Direct Yellow 4 compared to untreated samples, which result in a 50% inhibition rate. Similarly, Santana et al [51] also observed an increase in lettuce and clove seed germination when exposed to a treated sample of Reactive Red 195 compared to the parent compound as a result of complete mineralisation of the azo dye. The finding of Santana et al [51] also supported by the work of Roy et al [52] who reported significant improvement in chickpea seed germination when exposed to a treated sample of Reactive Yellow.…”

The finding of Santana et al [51] also supported by the work of Roy et al [52] who reported significant improvement in chickpea seed germination when exposed to a treated sample of Reactive Yellow. Therefore, it can be summarised that a proper decolourisation of a dye compound will result in total mineralisation, which significantly reduces the toxicity of the dye.…”

The application of microorganisms in azo dye remediation has gained significant attention, leading to various published studies reporting different methods for obtaining the best dye decolouriser. This paper investigates and compares the role of methods and media used in obtaining a bacterial consortium capable of decolourising azo dye as the sole carbon source, which is extremely rare to find. It was demonstrated that a prolonged acclimation under low substrate availability successfully isolated a novel consortium capable of utilising Reactive Red 120 dye as a sole carbon source in aerobic conditions. This consortium, known as JR3, consists of Pseudomonas aeruginosa strain MM01, Enterobacter sp. strain MM05 and Serratia marcescens strain MM06. Decolourised metabolites of consortium JR3 showed an improvement in mung bean’s seed germination and shoot and root length. One-factor-at-time optimisation characterisation showed maximal of 82.9% decolourisation at 0.7 g/L ammonium sulphate, pH 8, 35 °C, and RR120 concentrations of 200 ppm. Decolourisation modelling utilising response surface methodology (RSM) successfully improved decolourisation even more. RSM resulted in maximal decolourisation of 92.79% using 0.645 g/L ammonium sulphate, pH 8.29, 34.5 °C and 200 ppm RR120.

“…For the systems involving radiation, three types of radiation were applied: UV-C, sunlight (artificial solar), and natural solar. Except for the photolysis procedure, all the tests were performed using [H 2 O 2 ] at 50 mg L −1 , applied fractionally at the half concentration at times from 0 to 15 min (Santana et al, 2019). The concentration of [H 2 O 2 ] was calculated through stoichiometric equations (data not shown) of the degradation reaction of each dye in the presence of this as an oxidant (Ilha et al, 2009;Kumar et al, 2021).…”

groups and reduction of the chemical oxygen demand. The post-treatment samples were tested for toxicity on lettuce Lactuca sativa germination to verify the effect of the advanced oxidation process employed. The most efficient treatment determined in the preliminary study was photo-Fenton assisted by sunlight radiation. Under the best conditions developed and analyzed with the experimental designs, a 99% degradation of the chromophore groups was achieved, and a 98.72% decrease in chemical oxygen demand, in 120 min. The experimental data were well represented by the nonlinear kinetic model proposed by Chan and Chu with values of R 2 > 0.95. The toxicity test results demonstrated a decrease in the root growth of the species Lactuca sativa. The results demonstrate that the photo-Fenton system assisted by sunlight Abstract Effluents from the food industry regularly contain synthetic dyes that cause damage to ecosystems and water bodies. The present work aimed to evaluate homogeneous advanced oxidation processes for the mixed degradation of food dyes blue 1 and yellow 6. Through preliminary studies of advanced oxidation processes by photolysis, UV/H 2 O 2 , Fenton, and photo-Fenton, applying UV-C, artificial solar (sunlight), and natural solar radiation, the system with the best performance for the integral optimization of the treatment was determined. Based on the treatment with the best results, the multilevel factorial design 2 2 × 3 1 and central composite design 2^2 + star were created to optimize the variables [H 2 O 2 ], [Fe], and pH. The kinetics of the process was evaluated based on the percentages of degradation of the chromophore

“…The results obtained at each point (analysis of concentration of equilibrium) were subsequently used as a basis on which to employ the kinetic model described by Chan and Chu [36]. The results indicated that the pseudo-first order [37] could be employed for the degradation process by applying Equation (1).…”

“…It is worth highlighting that this will also depend on the type of seed analyzed, since the Daucus carota were affected to a greater extent as regards to their root growth ( Figure 10). In [37], Napoleão et al pointed out that, in the case of species such as Impatiens balsamina, Celosia cristata, and Americano Hard, when carrying out a toxicity analysis after applying AOPs, the growth of the species analyzed have been affected.…”

Oxytetracycline is one of the antibiotics most frequently used in the Shrimp Industry during the control of bacterial diseases. These emerging pollutants, which appear in low concentrations, are persistent and alternative treatments and are required for their elimination. The degradation of oxytetracycline was evaluated in an aqueous solution by applying homogeneous (UV/H2O2 and photo-Fenton) and heterogeneous (UV/TiO2/H2O2) advanced oxidative processes (AOPs). The studies were carried out using a bench reactor with short-wave ultraviolet lamps (UV-C). We quantified the extent to which the degradation of the drug had been efficient by employing highly efficient liquid chromatography (HPLC) and a PDA detector with a wavelength of 354 nm and a C18 column. The best results were obtained when applying the UV/H2O2 treatment, which attained a degradation of 97% under the initial conditions of a dose of 8 µL of H2O2 and 120 min of radiation. The pseudo-first order kinetic model proposed by Chan and Chu showed that the experimental results had an adequate fit, with values greater than R2 ≥ 0.95. Toxicity tests were applied to verify the effect of AOPs employed, when the drug was present in low concentrations. The test results demonstrated a decrease in the root growth of the species Lactuca sativa and Daucus carota.
