Abstract Coastal systems have seen increasing pressure from anthropogenic activities since the beginning of the century, affecting the health of these ecosystems. This increased pressure takes the form of an increase discharge of terrestrial organic matter (OM) and nutrients, leading to a higher primary productivity in the surface waters and to higher ...

Electrochemical activity of Geobacter sulfurreducens biofilms on stainless steel anodes [PDF]
Stainless steel was studied as anode for the biocatalysis of acetate oxidation by biofilms of Geobacter sulfurreducens. Electrodeswere individually polarized at different potential in the range−0.20V to +0.20V vs. Ag/AgCl either in the same reactor or in

Spatially resolved Shewanella–acetogen interactions link DIET and MET pathways to acetate formation, offering a generalizable framework for designing structured, high‐efficiency microbial electrosynthesis systems. Abstract Precise manipulation of interspecies electron transfer (IET) is critical for advancing microbial electrosynthesis (MES) toward ...

Recent advances in electron transfer between biofilms and metals [PDF]
Microbial biofilms produce electrochemical interactions with metal surfaces by following a wide variety of different electron exchange pathways. Reviewing the mechanisms identified in the biocorrosion of steels leads us to distinguish direct and indirect

The Role of Fe(II) Minerals in Carbon Stabilization in Coastal and Estuarine Anoxic Environments
Abstract Fe(III) (oxyhydr)oxides are well‐known for their role in organic carbon (OC) stabilization in terrestrial soils. Coastal and estuarine soils typically act as iron sinks and receive a high input of OC. However, tidal submersion induces anoxic and reducing conditions that favor the microbial reductive dissolution of Fe(III) (oxyhydr)oxides ...

Forming microbial anodes under delayed polarisation modifies the electron transfer network and decreases the polarisation time required. [PDF]
Microbial anodes were formed from compost leachate on carbon cloth electrodes. The biofilms formed at the surface of electrodes kept at open circuit contained microorganisms that switched their metabolism towards electrode respiration in response to a ...

This work experimentally validates the integration of bioelectrochemical energy based on the microbial fuel cells (MFC) into a hybrid PV‐battery system for off‐grid aquaculture IoT monitoring. Results demonstrate that MFC integration reduces battery discharge by 6.1% extending operational lifespan while minimising electronic waste. ABSTRACT Internet of

Millimetre‐Scale Stratification of Microbial Communities in Hydrothermal Sediments
Zooming into the millimetre‐scale spatial distribution of organic molecules in hydrothermally impacted sediments using mass spectrometry imaging reveals a distinct lipid zonation with abrupt transitions at critical redox interfaces. This zonation reflects a pronounced stratification of diverse microbial communities and highlights surprisingly ...
