“…Mostly, to reduce the negative impacts of conventional textile processing techniques, researchers have been focused on the development of more eco-friendly alternatives. These techniques have been aiming to reduce the environmental impact of textile processing while maintaining or improving the quality of the textile products (Dong et al, 2020; Hussain and Wahab, 2018; Periyasamy et al, 2018). Innovations of the machinery and industrial processes, for example, could be used to reduce the use of salts and achieve more neutral operational processing (Kulshreshtha et al, 2010; Hussain and Wahab, 2018).…”

Eco-friendly agents, such as chitosan, enzymes, and plant-based extracts, could also be used to replace conventional chemicals and promote more sustainable conditions (Senthil Kumar and Gunasundari, 2018; Periyasamy et al, 2018).…”

Textile effluents, although their composition can vary considerably, typically contain high levels of dissolved salts and exhibit wide variations in pH. Ecotoxicological studies regarding the effects of these parameters, however, have been limited owing to the need for sensitive and easy-to-handle bioindicators that require low amounts of sampling, are cost-effective, time-efficient, and ethically endorsed. This kind of study, additionally, demands robust multi-factorial statistical designs that can accurately characterize the individual and combined relationship between variables. In this research, Response Surface Methodology (RSM) was used to calculate the individual and interaction effects of NaCl concentration and pH value of a Simulated Textile Effluent (STE) on the development rate (DR) of the bioindicators: Bacillus subtilis bacteria and Lactuca sativa lettuce. The results demonstrated that the bioindicators were sensitive to both NaCl and pH factors, where the relative sensitivity relationship was B. subtilis > L. sativa. The quadratic equations generated in the experiments indicated that increased concentrations of 50-250 mg L−1 of NaCl caused a perturbance of 1.40%–34.40% on the DR of B. subtilis and 0.50%–12.30% on L. sativa. The pH factor at values of 3–11 caused an alteration of 27.00%–64.78% on the DR of the B. subtilis and 51.37%–37.37% on the L. sativa. These findings suggest that the selected bioindicators could serve as effective tools to assess the ecotoxicological effects of textile effluents on different ecological systems, and the RSM was an excellent tool to consider the ecotoxicological effects of the parameters and to describe the behavior of the results. In conclusion, the NaCl and pH factors may be responsible for disrupting different ecosystems, causing imbalances in their biodiversity and biomass. Before discharge or reuse, it is suggested to remove salts and neutralize pH from textile effluents and, mostly, develop novel, eco-friendlier textile processing techniques.

“…Textile industries besides having a contribution to the development of the global economy, water pollution by textile effluents is one of the major concerned issues over the world. One million tons of synthetic dyes are produced each year worldwide and approximately 280,000 tons of these dyes are emitted to the industrial effluents annually [1] [2]. Because of their nondegradable nature, these dyes inhibit the entrance sunlight in water and hamper the photosynthesis process, thus affecting the aquatic flora and fauna [3] .…”

Water pollution from textile effluent is now one of the major issues all over the world. Malachite Green dye of the triphenylmethane group is a key component of textile effluents. This study aimed to isolate and identify potential Malachite Green dye degrading bacteria from textile effluents. Different growth and culture parameters such as temperature, pH, inoculum-size and dye concentration were optimized to perform the dye-degradation assay using different concentrations of Malachite Green dye in mineral salt medium. A photoelectric-colorimeter was used to measure the decolorizing activity of bacteria at different time intervals after aerobic incubation. Two competent bacterial strains of Enterobacter spp. (CV-S1 and CM-S1) were isolated from textile effluents showing potential degradation efficiency against Malachite Green dye. The RAPD analysis and 16S rRNA sequencing confirmed the genetical difference of the isolated strains Enterobacter sp. CV-S1 and Enterobacter sp. CM-S1. The two bacterial strains CV-S1 and CM-S1 showed complete Malachite Green dye degradation up to 15 mg/l under shaking condition with 5% (v/v) inoculums at pH 6.50 and temperature 35°C within 72 and 144 hours respectively. These findings indicate that the two potential bacterial strains can be used in large scale treatment of textile effluents in the future.
