Development of efficient electroactive biofilm in urine-fed microbial fuel cell cascades for bioelectricity generation

Resilience and limitations of MFC anodic community when exposed to antibacterial agents

“…For instance, MFC 2 produced almost two times more power (1.2mW) than MFC 4 (0.7mW), which in turn produced two times more power than MFC 6 (0.35mW), which received a more depleted urine feed. These results are similar to power outputs from similar MFCs previously reported [10] .…”

“…The introduction and implementation of MFC technology in the field (domestic or industrial) means that it would be subject to both natural and anthropogenic elements, which could adversely affect its overall performance. The anodic biofilm of MFCs is composed of complex mix of microbial communities of fermentative and electroactive organisms working together in synergy to achieve efficient degradation of substrates [9] , [10] . Nevertheless, the ability of the anodic biofilm to metabolise the feed substrate depends on the nature of the substrate and its constituent concentrations.…”

Electricity generation and pollutants removal of landfill leachate by osmotic microbial fuel cells with different forward osmosis membranes

“…The land ll leachate also contained a certain salinity, resulting in high salinity of the anolyte. Arcobacter belongs to the εproteobacteria class whose bioelectrochemical activity has been reported [41,42].The percentage of Arcobacter in ES-OsMFC (9.54%) was higher than in NW-OsMFC (6.01%) and TFC-OsMFC (0.35%). This might be one of the reasons why ES-OsMFC had a better power generation effect (Fig.…”

Impact of selected environmental factors on microbiome of the digestive tract of ruminants

“…An experiment carried out on mice showed that the digestive system is equipped with molecular mechanisms that monitor the state of the intestinal lumen, thanks to which the activity and mobility of neurons is adjusted accordingly. However, these mechanisms are not fully known [ 70 , 73 , 74 , 77 ].…”
