Polydopamine-coated photoautotrophic bacteria for improving extracellular electron transfer in living photovoltaics

Fabian Fischer, Ardemis Anoush Boghossian, Charlotte Elisabeth Marie Roullier, Melania Reggente, Mohammed Mouhib, Patricia Brandl, Hanxuan Wang

Living photovoltaics are microbial electrochemical devices that use whole cell–electrode interactions to convert solar energy to electricity. The bottleneck in these technologies is the limited electron transfer between the microbe and the electrode surfac ...

Non-targeted facilitation of primary sludge anaerobic fermentation by micro-aeration and the simultaneous nutrients transformations

Mohammed Mouhib, Lin Li, Qiang He, Chenxi Liu

Anaerobic fermentation is a widely used technology for resource recovery from municipal sludge (e.g., primary sludge). Micro-aeration is an emerging strategy which can be incorporated into this technology. However, the effect of micro-aeration on the anaer ...

Engineering extracellular electron transfer for enhanced energy harvesting in microbial electrochemical devices

Mohammed Mouhib

Microorganisms known as exoelectrogens evolved the ability of transporting electrons across insulating biological membranes. In a physiological context, this enables respiration on extracellular electron acceptors and electron transfer to other organisms. ...

Extracellular electron transfer pathways to enhance the electroactivity of modified Escherichia coli

Ardemis Anoush Boghossian, Nils Schürgers, Melania Reggente, Mohammed Mouhib

Escherichia coli (E. coli) show limited extracellular electron transfer (EET) that compromises their use in bioelectronics. We enhance the EET in E. coli by expressing an electron transfer pathway that spans the inner and outer membranes of the cell, inclu ...

Carbon nanotube uptake in cyanobacteria for near-infrared imaging and enhanced bioelectricity generation in living photovoltaics

Vitalijs Zubkovs, Ardemis Anoush Boghossian, Alessandra Antonucci, Charlotte Elisabeth Marie Roullier, Nils Schürgers, Benjamin Paul Johanès Gabriel Lambert, Alice Judith Gillen, Melania Reggente, Mohammed Mouhib

Single-walled carbon nanotubes (SWCNTs) have unique optoelectronic properties that make them suitable for applications ranging from phototherapy to imaging and sensing, but their uptake has mainly been explored in eukaryotic cells. Here the authors explore ...

Enhancing bioelectricity generation in microbial fuel cells and biophotovoltaics using nanomaterials

Amirmostafa Amirjani, Ardemis Anoush Boghossian, Alessandra Antonucci, Alice Judith Gillen, Melania Reggente, Mohammed Mouhib

Microbial fuel cells and biophotovoltaics represent promising technologies for green bioelectricity generation. However, these devices suffer from low durability and efficiency that stem from their reliance on living organisms to act as catalysts. Such lim ...
