From two sensors to a single sensor: Better understanding of oxygen–sulfide interfaces

Limnology and Oceanography: Methods, Volume 21, Issue 10, Page 606-614, October 2023., 2023
Abstract Intense biogeochemical transformations in sediments and biofilms may occur over sub‐mm distances. Our current understanding of those transformations in such narrowly stratified environments has been facilitated by the introduction of microsensors.

In‐situ PLL‐g‐PEG Functionalized Nanopore for Enhancing Protein Characterization

Chemistry – An Asian Journal, Volume 18, Issue 17, September 1, 2023., 2023
In‐situ functionalization of thin PLL‐g‐PEG on SiN nanopores based on the self‐assembly and electrostatic interaction between the nanopore and PLL backbone of PLL‐g‐PEG is reported. This functionalization of SiN nanopores leads to non‐sticky protein translocation and volume estimation of individual proteins.

Interaction of living cable bacteria with carbon electrodes in bioelectrochemical systems. [PDF]

Appl Environ Microbiol
Cable bacteria are filamentous bacteria that couple the oxidation of sulfide in sediments to the reduction of oxygen via long-distance electron transport over centimeter distances through periplasmic wires.

Living electronics: A catalogue of engineered living electronic components

Microbial Biotechnology, Volume 16, Issue 3, Page 507-533, March 2023., 2023
Biology leverages a range of electrical phenomena to extract and store energy, control molecular reactions and enable multicellular communication. Recently, the microbial machinery enabling these redox reactions have been leveraged for interfacing cells and biomolecules with electrical circuits for biotechnological applications.

Sulfate biosensor for environmental applications

Limnology and Oceanography: Methods, Volume 20, Issue 10, Page 674-681, October 2022., 2022
Abstract Sulfate is present in all freshwater and marine environments and is reduced to toxic and corrosive hydrogen sulfide by anaerobic bacteria. By measuring depth profiles of sulfate in sediments, it is possible to obtain estimates of sulfate reduction rates (SRRs).

Redox Mediators in Microbial Electrochemical Systems

ChemElectroChem, Volume 9, Issue 13, July 14, 2022., 2022
Electron transfer mechanisms: in microbial electrochemical systems is crucial for understanding and optimizing these processes. This review focused on mediated electron transfer and gave the reader a handbook for mediator selection by stating the relevant redox potentials and microbial interaction sites. Furthermore, the review focused on what mediator

Enhanced benthic nitrous oxide and ammonium production after natural oxygenation of long‐term anoxic sediments

Limnology and Oceanography, Volume 67, Issue 2, Page 419-433, February 2022., 2022
Abstract Coastal and shelf sediments are central in the global nitrogen (N) cycle as important sites for the removal of fixed N. However, this ecosystem service can be hampered by ongoing deoxygenation in many coastal areas. Natural reoxygenation could reinstate anoxic sediments as sites where fixed N is removed efficiently. To investigate this further,

Halobacterium salinarum NRC‐1 Sustains Voltage Production in a Dual‐Chambered Closed Microbial Fuel Cell

The Scientific World Journal, Volume 2022, Issue 1, 2022., 2022
Sustained bioenergy production from organisms that thrive in high salinity, low oxygen, and low nutrition levels is useful in monitoring hypersaline polluted environments. Microbial fuel cell (MFC) studies utilizing single species halophiles under salt concentrations higher than 1 M and as a closed microbial system are limited.

Cable bacteria at oxygen‐releasing roots of aquatic plants: a widespread and diverse plant–microbe association

New Phytologist, Volume 232, Issue 5, Page 2138-2151, December 2021., 2021
Summary Cable bacteria are sulfide‐oxidising, filamentous bacteria that reduce toxic sulfide levels, suppress methane emissions and drive nutrient and carbon cycling in sediments. Recently, cable bacteria have been found associated with roots of aquatic plants and rice (Oryza sativa).
