“…Additionally, the voltage values are in line with what other authors have reported [24,25]. In a prior study, Jamlus et al [26] discovered that K. pneumonia, K. variicola, B. licheniformis, and B. velezensis were the strains of electroactive bacteria that generated electricity, whereas abiotic experiments were performed without the substrate containing any electroactive bacteria. Both electroactive bacteria and abiotic sources of energy produced positive overall values.…”

A microbial fuel cell (MFC) is a type of device which is an electrochemical, after technology that is being to recover electricity from wastewater. This study's objective was to measure the potential difference from sludge collected from El-Sheikh Zayed water purification plant (Egypt in April 2021), isolate and identify bacteria present in sludge: Also, determine the effect of adding some metabolites on such physical and chemical properties. Potential difference measurement showed (192 mV) by using MFC. Pantoea spp., Aeromonas salmonicida, Comamonas testosteroni and Staphylococcus lentus were isolated and identified by biochemical reaction tests. A. salmonicida gave the highest potential difference (13mV). After adding some metabolites separately (albumen, dextrose, gelatin and casein), casein recorded 196Mv, a mixture was done between A. salmonicida and four metabolites measuring 50 mV. Physical and chemical analysis showed that biochemical oxygen demand (BOD) (55.0 P.P.M.), chemical oxygen demand (COD) (112.0 P.P.M.), and many minerals and heavy metals were also detected. Green synthesis of electricity from electrogenic bacteria using wastewater like sludge is a promising way to generate electricity by a cheap method.

“…In this pretext, Bacillus velezensis, an electrogenic microbe is found in a variety of habitats, such as water bodies, soil, etc., has a lower iron reduction potential; therefore, it produces lower electricity when compared with Shewanella and Geobacter species (Jamlus et al 2021). The transfer of electrons for the Bacillus velezensis can take place either through membrane-assisting components or through soluble electron shuttles or nanowires (Zuo et al 2006;Kalaiselvi and Panneerselvam 2021).…”

Various microbial strains and techniques are being used to improve power production in microbial fuel cells. Cow dung is a peculiar source of anaerobic and micro-aerophilic organisms that were employed in this study to isolate exo-electrogenic microorganisms. To validate their exo-electrogenic nature, all eight visually distinct bacterial single-cell colonies were tested using the ferrocyanide reduction assay, which resulted in the selection of one bacterial strain AD1-ELB with the ability to reduce ferrocyanide for further biochemical, physiological and electrochemical characterization. The selected strain AD1-ELB was identified as Bacillus velezensis by 16 s rRNA gene sequencing. When used in a single-chambered MFC, the isolated AD1-ELB strain produced a maximum open-circuit voltage of 455 mV with a maximum current density of 51.78 µA/cm 2 and maximum power density of 4.33 µW/cm 2 on the 16th day. Bacillus velezensis AD1-ELB strain was treated with lowfrequency ultrasound (40 kHz) for 1, 2, 3, 4, and 5 min to assess the effect of ultrasonic pre-treatment on an isolated pure culture-based microbial fuel cell. A 3-min exposure to low-frequency ultrasonic therapy resulted in an increase in maximum power of 4.33 µW/cm 2 with a current density of 51.78 µA/cm 2 in the MFC, which decreases significantly after 4 and 5 min. Thus, the overall power density achieved was 1.89 times greater than in MFCs with untreated strain. These findings support the use of low-frequency ultrasonic stimulation to improve the performance of microbial fuel cell devices and are restricted to the pure, single-cell strain AD1-ELB, with the potential for variation if some other isolated strain is utilized, hence requiring further study to determine its relative variations.

“…S. oneidensis is reported as having electrical activity and is involved in the production of electric current [144][145][146][147][148][149][150]. Bacillus and Klebsiella both strains can produce electric current [151]. Organic carbon content in the soil is also one of the major factors which influence the production of electric current [11].…”

Bacteria with the remarkable ability to transport electrons both intra and extracellularly for renewable energy production and environmental remediation. Nowadays, some bacteria have applications in the field of environmental sciences as well as physics, involving the production of useful substances and electric current. Prokaryotes have the potential to use charged electrodes to donate and accept electrons. These bacteria use a mechanism namely extracellular electron transport (EET) for multiple purposes; small power sources, pollution remedy, water reclamation, and electrosynthesis. Researchers are currently working on bacteria having EET ability at a basic level and looking forward to remarkable applications in the future. Microbial fuel cells (MFCs) are recognized as the most potent candidate for future alternative energy production. Nanowires such as those produced by Geobacter sulfurreducens and Shewanella oneidensis, facilitate electron transfer over longer distances, enhancing the efficiency of bioelectricity generation. This review briefly explains the components of bacteria involved in the EET mechanisms for the production of electric current and the role of biofilm for electrogenic bacteria. It also highlights the different methods used to promote the EET mechanism and some unusual external electrons used recently in MFC.
