“…Bacillus, Ochrobactrum, Clostridium and Pseudomonas covered almost equal percent (14-16%) of 0.05 dominance compare to other strains after 40 days of operation. Previous studies were in agreement with the strains reported in the present study such Bacillus (Shaikh et al 2016), Clostridium (Ekambaram et al 2016) and Pseudomonas (Jayaprakash et al 2016) to treat dye wastewater in MFC. Ochrobactrum was reported as dominant strain by Jayashree et al (2015) in continuous upflow MFC to treat retting pond wastewater.…”

Single chamber air cathode microbial fuel cell (MFC) is a promising and sustainable technology to generate electricity. In the present study, the potential of air cathode MFC treating dye processing wastewater was investigated at various organic loads with interest focused on power densities, organic removal and coulombic efficiencies. The highest power density of about 515 mW/m 2 (6.03 W/m 3) with 56% of coulombic efficiency was procured at 1.0 (g COD/L) organic load. The high potency of TCOD (total chemical oxygen demand), SCOD (soluble chemical oxygen demand) and TSS (Total Suspended Solids) removal of about 85%, 73% and 68% respectively was achieved at the organic load of 1.0 (g COD/L). The bacterial strains in anode region at the initial stage of MFC operation were reported to be responsible for potential organic removal. The bacterial strains in air cathode MFC were identified as Paenibacillus sp. strain JRA1 (MH27077), Pseudomonas sp. strain JRA2 (MH27078), Ochrobactrum sp. strain JRA3 (MH27079), Sphingobacterium sp. strain JRA4 (MH27080), Stenotrophomonas sp. strain JRA5 (MH27081), Bacillus sp. strain JRA6 (MH27082) and Clostridium sp. strain JRA7 (MH27083) using phylogenetic analysis. After 60 days of air cathode MFC operation, the bacterial community in biofilm samples was dominated by Bacillus, Ochrobactrum and Pseudomonas (20-22%). The biofilm sample collected from the carbon brush consisted of Bacillus (33%), Ochrobactrum (30%), Pseudomonas (28%), Clostridium (6%) and Stenotrophomonas (3%). The present study revealed the treatment efficiency of dye processing wastewater along with power generation in single chambered air cathode MFC.

“…For instance, SCFAs, when used as fermentation metabolites, can inhibit bacterial growth to achieve treatment effects 25 . In addition, it has been shown that B. circulans can convert biomass into electrical energy 10 . Its halophilic strain BBL03 can ferment 1% chitin and use degraded metabolites as electron donors to generate electricity in seawater; therefore, it can serve as electricity-producing bacteria in MFCs 26 .…”

“…During metabolism and EET, NADH is oxidised to NAD + through NADH dehydrogenase and delivers electrons to the extracellular space to reduce extracellular electron acceptors 10 . EET includes direct and indirect modes, such as conductive protein filaments (microbial nanowires 11 ), electron-shuttling mediators (flavin 12 or methyl viologen 13 ), and the extracellular polymeric substances of biofilms (redox proteins 14 ).…”

Bacillus circulans (B. circulans) is widely used as an electrogenic bacterium in microbial fuel cell (MFC) technology. This study evaluated whether B. circulans can ferment glucose to generate electricity and mitigate the effects of human skin pathogens. The electricity production of B. circulans was examined by measuring the voltage difference and verified using a ferrozine assay in vitro. To investigate the fermentation effects of B. circulans on inhibition of human skin pathogens, Cutibacterium acnes (C. acnes) was injected intradermally into mice ears to induce an inflammatory response. The results revealed that the glucose–B. circulans co-culture enhanced electricity production and significantly supressed C. acnes growth. The addition of roseoflavin to inhibit flavin production considerably reduced the electrical energy generated by B. circulans through metabolism and, in vivo test, recovered C. acnes count and macrophage inflammatory protein 2 (MIP-2) levels. This suggests that B. circulans can generate electrons that affect the growth of C. acnes through flavin-mediated electron transfer and alleviate the resultant inflammatory response. Our findings demonstrate that probiotics separated from natural substances and antimicrobial methods of generating electrical energy through carbon source fermentation can help in the treatment of bacterial infections.
