Over the past few decades, there has been a growing concern regarding fate and transport of pharmaceuticals, particularly antibiotics, as emerging contaminants in environment. It proposed that presence antibiotics at concentrations typically found wastewater can impact dynamics bacterial populations facilitate spread antibiotic resistance. The efficiency currently-used treatment technologies eliminating pharmaceuticals is often insufficient, resulting release low these compounds into In this study, we addressed challenges by evaluating how different influent ibuprofen (IBU) influenced laboratory-scale, integrated constructed wetland-microbial fuel cell (CW-MFC) system seeded with Eichhornia crassipes, terms organic matter removal, electricity generation, change community structure compared to unplanted, sediment MFC (S-MFC) abiotic S-MFC (AS-MFC). We observed addition IBU (5 mg L-1) resulted notable decrease chemical oxygen demand (COD) suggesting high caused partial inhibition for electroactive microbial due its complexity aromaticity. However, CW-MFC could recover from after an acclimation period unplanted S-MFC, even though level was increased up 20 L-1, plants CW-MFCs have beneficial role relieving anode respiration levels IBU; thus, promoting metabolic activity community. Similarly, removal (i.e., 49-62%) much higher SMFC 29-42%), AS-MFC 20-22%) during all experimental phases. addition, our throughput sequencing revealed performance associated increasing relative abundances several groups are closely affiliated fermentation. summary, results show demonstrates suitability effective generation.

Demand for energy resources is increasing rapidly, leading to excessive exploitation of fossil fuels. The production chicken, which a popular source protein, generates huge amount waste. Microbial fuel cells (MFC) have the potential generate clean, sustainable, and environmentally benign electricity by utilizing electrogenic bacteria present in chicken manure (CM), while also decreasing study was conducted assess effect different temperatures numbers chambers series parallel circuits on performance membrane-less MFCs (ML-MFCs). central composite design (CCD) based response surface methodology (RSM) applied optimize ML-MFCs circuits, with focus chemical oxygen demand (COD) removal efficiency (R2 = 0.958 0.967), biomass 0.995 0.836), power density 0.825). revealed that highest COD (series: 89.554 %, parallel: 84.994%), 1.095 mg/L, 2.267 mg/L), 0.551 W/m2, 0.360 W/ m2) were achieved when pre-treatment temperature 40°C. best ML-MFC condition plotted polarization curve order analyze nature ML-MFC. Findings this suggest great generation waste reduction, optimization operating conditions can enhance their performance.

Nonelectroactive clostridium obtains extracellular electron transfer-capability after forming chimera with Geobacter

ISME Communications, Journal Year: 2024, Volume and Issue: 4(1)

Published: Jan. 1, 2024

Abstract Extracellular electron transfer (EET) of microorganisms is a major driver the microbial growth and metabolism, including reactions involved in cycling C, N, Fe anaerobic environments such as soils sediments. Understanding mechanisms EET, well knowing which organisms are EET-capable (or can become so) fundamental to electromicrobiology geomicrobiology. In general, Gram-positive bacteria very seldomly perform EET due their thick non-conductive cell wall. Here, we report that Clostridium intestinale (C.i) attained EET-capability for ethanol metabolism only after forming chimera with electroactive Geobacter sulfurreducens (G.s). Mechanism analyses demonstrated was possible fusion two species achieved. Under these conditions, pathway C.i integrated by G.s, achieved oxidation subsequent reduction extracellular acceptors coculture. Our study displays new approach via recruiting an bacterium, suggests previously unanticipated prevalence world. These findings also provide perspectives understand energetic coupling between bacterial ecology interspecies mutualisms.

Published: May 14, 2024

Investigating biodegradable and biocompatible materials for electronic applications can lead to tangible outcomes such as developing green-electronic devices reducing the amount of e-waste. The proposed emulsion-based conducting ink formulation takes into consideration circular economy green principles throughout entire process, from selection production process. is formulated using biopolymer polylactic acid dissolved in a sustainable solvent mixed with water, along conductive carbon nanotubes (CNTs) silver flakes fillers. Hybrid fillers lower percolation threshold costs, while maintaining excellent electrical properties. coating formed after deposition ink, undergoes isothermal treatment at different temperatures durations improve its adhesion coating's performance was evaluated by creating an eight-finger interdigitated sensor Voltera PCB printer. demonstrates exceptional when exposed various loading unloading pressures within 0.2-500.0 kPa range. results show consistent correlation between change resistance stress caused applied load. marine environments, which helps avoiding accumulation ecosystem over time.
