AI summary
70% confidenceThis study investigates the environmental performance of microbial fuel cells (MFCs) using live sludge to produce voltage and remove Congo red dye from aqueous solutions. The results show that MFCs can achieve high decolorization rates and voltage output, with a maximum output voltage of 889 mV at pH 7.5. Microbial community analysis reveals the impact of bacteria on removal and voltage.

Abstract
In this work, Single chamber Microbial fuel cells (SCMFCs) are a versatile technology is depending on the interaction mechanisms of bacteria, to produce bioelectricity simultaneously and treat Congo red (CR) dye from aqueous solution at different pH (6.5-8). Electricity generation from the biodegradable organic substrate (sucrose) accompanied by decolorization of azo dye was investigated in the batch test results showed that more than 99% decolorization demonstrated at UV-Visible Spectrophotometer (500 nm) was achieved within 20 days and maximum output voltage (889 mv) had been obtained in an open circuit at a pH value of 7.5. Microbial community analysis showed that species in live sludge and the impact of bacteria grown on removal and voltage.
