摘要

The increasing discharge of untreated textile effluents into freshwater resources has created a serious environmental challenge for sustainable agriculture and human health worldwide. This study evaluated a Gram-negative bacterial strain isolated from dye-contaminated sites for its potential in bioremediation of textile wastewater. Molecular identification based on 16 S rRNA sequence showed 100% similarity with Serratia liquefaciens AM-2. PCR amplification confirmed the presence of a NADPH-dependent FMN reductase gene associated with azo dye reduction. The strain showed maximal decolorization efficiencies of 92%, 80%, and 82% for Reactive Black 5, Reactive Red-120, and Congo Red after 72 h of incubation. Molecular docking analysis revealed strong predictive interaction of its azoreductase protein with azo dye degradation. Laboratory-scale treatment of textile wastewater with strain AM-2 significantly reduced EC, TDS, TSS, COD, and BOD by 45.2%, 39.5%, 56.6%, 54.8%, and 52.3%. Rice plants irrigated with treated wastewater showed higher chlorophyll a (49%), carotenoids (33.33%), and root dry weight (68.8%) compared with untreated wastewater. The treated wastewater also reduced H₂O₂ and MDA content by 26.15% and 78%. These results suggest the potential use of S. liquefaciens AM-2 as an environmentally friendly approach for textile wastewater treatment and agricultural reuse.
