“…Despite the significant economic contribution, it has brought with it a range of environmental problems, mostly pollution of water resources. The textile industry consumes large quantities of water for various processes and discharges equally large volumes of wastewaters containing a variety of pollutants and coloring agents such as the azo dye 6,7 .…”

In the 21 century, environmental pollution has been Background: acknowledged as one of the major problems. The textile and dyeing industries contribute a major portion by discharging intensely complex effluent consisting of highly noxious azoic dyes.In this study, biological treatment using acclimatized microorganisms Methods: were employed in search of a cheap and eco-friendly substitute for color removal from textile waste. The microbial inocula were isolated from effluent soil samples and then applied to flasks containing azo dyes as the only source of carbon for decolorization.Biochemical tests postulated predominance of and Results: Enterococcus bacterial strains. CO isolate or emerged as the best Bacillus Bacillus farraginis decolorizer of Orange M2R dye, decolorizing 98% of the dye. BG isolate or showed maximum decolorization on Green GS dye Paenibacillus macerans that decolorized 97% of the dye. The optimum physiochemical condition for decolorization of OM2R and GGS dye was pH 7.0, 2% NaCl conc., 1% initial dye conc. and 37°C temperature by the selected isolates.The findings were validated and have the potential for Conclusions: bioremediation in textile waste effluent treatment plants.

This study was conducted to isolate and identify bacteria from the wastewater of the textile printing industry inoculated with a mixture of cow dung, jaggery, and urea to assess the bioremediation potential of isolated bacterial species for reducing color and other polluting parameters of the wastewater. Based on colony characteristics, we were able to isolate nine types of bacteria (Pri 1 to 9), capable of thriving in textile printing wastewater. Out of the nine isolates examined, four (Pri 3, Pri 4, Pri 8, and Pri 9) significantly reduced the color and values of other physicochemical parameters of the wastewater. Isolated bacterial cultures were identified using various biochemical tests, antibiotic sensitivity tests, and rRNA sequence analysis. At the end of a 24-h incubation period at room temperature under shaking conditions at 100 rpm on an orbital shaker, isolate Pri 3 was identified as Alcaligenes aquatilis LMG 22996 (T), capable of reducing color by 86.13%, biological oxygen demand (BOD) by 70.44%, chemical oxygen demand (COD) by 80.65%, total dissolved solids (TDS) by 47.31%, total suspended solids (TSS) by 56.56%, and ammoniacal nitrogen by 75.95%; isolate Pri 4 as Priestia aryabhattai B8W22(T), capable of reducing color by 78.35%, BOD by 66.35%, COD by 74.92%, TDS by 34.94%, TSS by 31.66%, and ammoniacal nitrogen by 71.14%; isolate Pri 8 as Citrobacter werkmanii NBRC 105721(T), capable of reducing color by 90.37%, BOD by 82.13%, COD by 85.06%, TDS by 54.83%, TSS by 61.97%, and ammoniacal nitrogen by 80.76%; and isolate Pri 9 as Shewanella chilikensis JC5(T), capable of reducing color by 90.17%, BOD by 84.68%, COD by 83.46%, TDS by 59.13%, TSS by 62.45%, and ammoniacal nitrogen by 90.37%.

In the current scenario of the need for cost-effective remediation, our study aimed to assess the remedial potential of bacteria obtained from metal-rich wastewater. To simulate the conditions, we prepared wastewater containing five toxic metals (Cu, Cr, Ni, Fe, and Pb). Two types of metal-resistant bacteria were isolated from a prominent wastewater drain in Lahore, Pakistan. These isolated bacteria were thoroughly characterized—both phenotypically and genotypically. Subsequently, the isolated bacteria were exposed to the wastewater solution containing each of the aforementioned metals at a concentration of 250 ppm. The exposed isolates were then incubated for a duration of 15 days. After 5 days, we measured the uptake of metals by the bacterial isolates. Following the 15-day incubation period, we observed that the bacterial isolates demonstrated the maximum efficiency in removing metals, with approximately 47.5% of Fe, 77% of Ni, 75.75% of Cu, 64% of Cr, and 82.5% of Pb being removed. These findings have significant implications for the development of environmentally friendly and cost-effective strategies for metal ion remediation.
