“…Red dye is also decomposed by Staphlococcus strain in MFC effectively. However, the power supply and output potential firstly rose with increasing dye coloring concentration and then the tendency of the dye was changed in later stages when the poisonous of the dye affects the microbe 49 . However, Wu et al 38 investigated toulene remediation from synthetic wastewater and Pseudomonas sp.…”

The water polluted with toluene could be treated using a membrane less single chamber benthic microbial fuel cells (SBMFCs) by using sugar cane waste as a substrate producing energy. Toluene oxidizes into intermediate benzoic acid and completely converts into non-toxic carbon dioxide. The BMFC generated a voltage of 0.530 V between 40 and 80 days when the external resistance was 1 kΩ. The highest power density and current density generated about 34.7 mW/m 2 and 120 mA/m 2 within 41 days. Furthermore, toluene remediation rate was 98.22% by BMFC. On the 41st day, redox curves were measured around À0.6 V (forward peak) and À0.5 V (reverse peak) while specific capacitance of 0.141 F/g. The Nyquist plot was fitted equivalent circuit from electroimpedance spectroscopy performed to measure overall internal resistance (54.81 Ω). The scanning electron micrographs showed that pores over multianode surface were improperly spaced, but these pores were for biofilm growth. The 16S rRNA pyro-sequencing results identified the Staphylococcus sp. and Pseudomonas sp. These results showed that BMFC could be used for the power production and the toluene remediation. In this work, sugarcane waste was used as a substrate in a multi-anode system, as well as toluene treatment and energy production with the help of SBMFC without membrane.

“…Increased power generation in MFCs is typically limited by cathode surface area and ingredients (Logan et al, 2007;Cheng et al, 2006a;Huang and Logan, 2008). As a result, identifying inexpensive components and efficient cathode topologies is critical for enhancing the affordability and efficacy of MFCs (Rabaey et al, 2005a;Shahi et al, 2021).…”

The present study addressed the application of sandwich-type air cathode microbial fuel cell (ACMFC) for the production of bioelectricity. Activated carbon was pasted on aluminum mesh for the manufacture of anode and cathode. This electrode design eliminated the requirement for carbon cloth or a metal catalyst, resulting in a cathode with excellent activity for oxygen reduction. The findings demonstrated that open circuit voltage (OCV) initially rose with duration due to microbial growth rate. Furthermore, decreases in voltage are seen, probably as a result of a decrease in sufficient feed for the number of microbes. When fed with glucose (substrate), OCV suddenly increased when the bacteria re-grow and then maintains a consistent amount. The current was recorded employing a multimeter, the same as the OCV. The produced current was found to have increased significantly. These results demonstrate that activated carbon is an economical substance for obtaining advantageous oxygen reduction rates in ACMFC.

“…Therefore, bioremediation offers a convenient solution in terms of low cost and environmentally friendly. Microorganisms such as bacteria, fungi, and algae have been known to decolorize and metabolize azo dyes under anaerobic and aerobic conditions, including Staphylococcus equorum RAP2 [5]; basidiomycetes (Phanerochaete chrysosporium ATCC 24725) [6] and Fucus vesiculosus [7].…”

Industrial use of azo dyes has been linked to severe environmental damage in the textile and apparel sectors. The breakdown products of many azo dyes are poisonous and mutagenic, posing a threat to human health and the environment. Hence, azo dye wastewater bioremediation is gaining interest. The objective of this study was focused on the biodegradation of an azo dye, Reactive Orange 16 (RO16), in an anaerobic continuous tank reactor operated with digested sludge sample. The digested sludge was used as the organic biodegradation agent for azo dye. The aim was to investigate the fate of the anaerobic RR16 breakdown products during the degradation process. Gas Chromatography-Mass Spectrophotometry (GC-MS) was used to identify RO16 biodegradation metabolites and their corresponding molecular weight. As a result, RO 16 showed about 85.91% decolorization capacity, and the degradation metabolites were detected as pentanoic acid and phenol after seven days of incubation. The degradation mechanism was completed as the azo bond of RO16 was successfully cleaved based on the result of GC-MS, and the proposed pathway of the degradation mechanism is described. The digested palm oil sludge with dye degradation enzymes may provide new avenues for biological waste treatment, especially wastewater bioremediation.
