“…Exposure to these textile effluents could result in the dysfunction of organs, specifically the kidney, reproductive system, liver, brain and central nervous system [ 2 , 3 ]. For instance, malachite green (MG) is extensively used in the textile industry [ 4 , 5 ]. The discharge of MG effluent gives undesirable color to the effluent, and it reduces the penetration of sunlight into the river or lake which threatens the life of the aquatic ecosystem with hypoxiation.…”

Textile industry effluent contains a high amount of toxic colorants. These dyes are carcinogenic and threats to the environment and living beings. In this study, poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-co-HFP) was used as the based polymer for PIMs with bis-(2-ethylhexyl) phosphate (B2EHP) and dioctyl phthalate (DOP) as the carrier and plasticizer. The fabricated PIMs were employed to extract the cation dye (Malachite Green; MG) from the feeding phase. PIMs were also characterized by scanning electron microscopy (SEM), atomic force microscope (AFM), contact angle, water uptake, Fourier-transform infrared spectroscopy (FTIR) and ions exchange capacity. The performance of the PIMs was investigated under various conditions such as percentage of carrier and initial dye concentration. With permeability and flux values of 0.1188 cm/min and 1.1913 mg cm/min, PIM produced with 18% w/w PVDF-co-HFP, 21% w/w B2EHP, 1% w/w DOP and 40% w/w THF and was able to achieve more than 97% of MG extraction. The experimental data were then fitted with a pseudo-second-order (PSO) model, and the calculated R2 value was ~0.99. This shows that the data has a good fit with the PSO model. PIM is a potential alternative technology in textile industry effluent treatment; however, the right formulation is crucial for developing a highly efficient membrane.

“…CM-S1 from textile effluent which they used to decolourise malachite green (MG). The results showed that the two strains could completely decolourise 15 mg/L of the dye in 78 and 144 h respectively at optimized pH of 6.5 and temperature of 35 °C without the need of additional carbon and protein sources [ 151 ]. This means that these species can use the dye as their carbon and energy source for their growth.…”

“…Microbes play significant role in the field of bioremediation and may be very fruitful in saving environment from the different types of pollution. [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23] Many publications of authors have also valuable information in the field of microbial bioremediation. [5][6][7][8][9] Use of microbes in the treatment of dyes is bright research area of the green chemistry sector because it neither requires any drastic conditions nor produces any toxic pollutants or toxic by-products.…”

Dyes are colored substances being used to color various types of fabrics and materials from ancient time. During their use in the coloring of various types of materials as well as during their synthesis; they come out in the environment as such or in the form of toxic by-products and by mixing in aqueous system generate various types of problems to organisms living in that aqueous environment as well as human beings using that polluted water in any way. Several techniques are being used in the present time to solve such environmental problems. In this direction, many researches are also running on the green use of microbial technology in bioremediation of toxic, carcinogenic and extremely harmful unused dye’s products as well as its by-products by elimination or degradation or de-colorization. This mini-review discusses about the some recent researches done in this field in order to solve this problem and future aspect of the use of this green technology
