A Cyanobacterium Treated Textile Wastewater for the Plant Growth Enhancement: Experimental Study

Phycoremediation of textile dye sample collected from the industrial area of PGC Textile Corporation Private Limited, Tirupur, and was carried out by using certain Cyanophyceae members of microalgae such as Oscillatoria boryana CAS101, Phormidium calcicola CAS102, and Synechocystis pevalakii CAS103. The treatment of effluent was analyzed by investigation of various parameters on control and treated effluent. The biochemical studies in treated effluent using the algae revealed that there is an increase in the level of protein up to 10%, 13% carbohydrate, 14% chlorophyll a, 16% chlorophyll b, 13% carotenoid, and 29% lipid. The textile dye color was decolorized from blue to green, and the pH level also increased from 5.7 to 7.5 due to the influence of the tested organisms. Reduction in absorbance was marked at various ranges from 385 to 280 nm of the UV spectrum. The degradation ability of S. pevalakii CAS103 was determined using FT-IR spectrum analysis, which revealed that the microalgae grown medium and effluent added grown medium showed shifting of intensity and peaks at 1076 cm(-1) and 1036 cm(-1), respectively. Finally, the result indicated that textile dye treatment using 385 nm to 280 nm seems to be a feasible technique for bioremediation of textile dye. The present investigation was found to be a very useful, sensitive, biological, and rapid treatment method for dye degradation.

Automated summary

This study conducted phycoremediation experiments on textile dye samples from PGC Textile Corporation Private Limited. Results showed that the microalgae used in the experiment resulted in an increase in protein, carbohydrate, chlorophyll, carotenoid, and lipid content in the treated effluent. The color of the dye was decolorized and the pH level increased. The study also analyzed the degradation ability of one of the microalgae using FT-IR spectrum analysis. The findings suggest that the spectral treatment technique is a feasible method for the bioremediation of textile dye.
