Initially, optimization of sulfate reduction was performed at different sulfate concentrations (100-900 mg/L) and the constant COD of 1000 mg/L, corresponding to COD/sulfate ratio of 1.11-10, and varying HRT of 12-48h. Optimum COD/sulfate ratio and HRT was found 1.66 and 36h, respectively, corresponding to 96% COD removal, 44% sulfate removal and yielded about 24 W/m2 power density. Further, MFC was fed with azo dye containing (50-1000 mg/L) simulated wastewater to evaluate dye removal performance of sulfate reducing bacteria. Addition of azo dye slightly enhanced the power production to 26 W/m2, the highest value obtained during our study, compared to azo dye lacking study periods. Sulfate and COD removals were adversely affected at azo dye concentrations over 300 mg/L and 150 mg/L, respectively. Additionally, color removal performance of MFC was excellent however, chemical azo dye reduction out-competed with enzymatic reduction at high azo dye levels (>500 mg/L) leading to a poor sulfate (<15%) and COD (<45%) removal and recovery of azo dye reduction efficiency to 91%.</p> </p></abstract><publication_date><month>06</month><day>13</day><year>2019</year></publication_date><pages><first_page>381</first_page><last_page>388</last_page></pages><publisher_item><identifier id_type="pii">gnest_02926</identifier></publisher_item><doi_data><doi>10.30955/gnj.002926</doi><timestamp>1714134028</timestamp><resource>https://journal.gnest.org/publication/gnest_02926</resource></doi_data></journal_article></journal></body></doi_batch> </div>
