Randomized trial shows significant decolorization of Reactive Red 111 in saline-alkaline conditions, indicating an eco-friendly treatment option.
Key Points
This study aims to evaluate the effectiveness of a microbial consortium from mangroves in decolorizing Reactive Red 111 dye under saline-alkaline conditions.
Isolated haloalkaliphilic microbial consortium from Bhadeli mangrove ecosystem.
Evaluated decolorization efficiency under varying dye concentrations (100-1000 mg/L) and conditions (pH 7.5-8, NaCl 10 g/L).
Characterized microbial community using 16S rRNA sequencing and analyzed degradation pathways through LC–MS and FTIR.
Achieved 96.58% decolorization of Reactive Red 111 within 8 hours under optimal conditions.
Maintained >95% efficiency across dye concentrations and significant tolerance to extreme salinity (100 g/L NaCl) and alkalinity (pH 11).
Phytotoxicity analysis revealed substantial removal of toxicity post-treatment.
