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.

Zeolite stimulates the activity of microbial enrichments converting butyrate to methane [PDF]

, 2021
Conductive materials have been tested as a strategy to improve methane production (MP) in anaerobic digestion (AD) processes1,2. The effect of zeolite (0.5 g/L) towards microbial enrichments converting butyrate (10 mmol/L) to methane was investigated and

Pure cultures of hydrogenotrophic methanogens are affected by modified activated carbons, zeolite, sand and glass beads [PDF]

, 2021
The metabolism of hydrogenotrophs has been showed to be improved in the presence of carbon nanotubes, which is relevant since they are crucial microorganisms in the conversion of waste to methane1.

Cable bacteria reduce methane emissions from rice-vegetated soils

Nature Communications, 2020
Rice paddies are a major source of the Earth’s atmospheric methane, making these important food crops potent contributors to greenhouse gas emissions. Here the authors show that inoculation of paddies with a particular bacterium could significantly curb ...

Tracing and regulating redox homeostasis of model benthic ecosystems for sustainable aquaculture in coastal environments

Frontiers in Microbiology, 2022
Aquaculture in coastal environments has an increasingly important role in the world’s food supply; however, the accumulation of organic compounds on seafloors due to overfeeding adversely affects benthic ecosystems. To assess the ecological resilience of

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
