In vivo polydopamine coating of Rhodobacter sphaeroides for enhanced electron transfer

Ardemis Anoush Boghossian, Melania Reggente, Fabian Fischer

Recent advances in coupling light-harvesting microorganisms with electronic components have led to a new generation of biohybrid devices based on microbial photocatalysts. These devices are limited by the poorly conductive interface between phototrophs and ...

Reactivity of Cyanobacteria Metabolites with Ozone: Multicompound Competition Kinetics

Urs von Gunten

Cyanobacterial blooms occur at increasing frequency and intensity, notably in freshwater. This leads to the introduction of complex mixtures of their products, i.e., cyano-metabolites, to drinking water treatment plants. To assess the fate of cyano-metabol ...

Collective motion in a sheet of microswimmers

Viktor Skultéty

Self-propelled particles such as bacteria or algae swimming through a fluid are non-equilibrium systems where particle motility breaks microscopic detailed balance, often resulting in large-scale collective motion. Previous theoretical work has identified ...

Interactions between pili affect the outcome of bacterial competition driven by the type VI secretion system

Melanie Blokesch, Anne-Florence Raphaëlle Bitbol, Alexandre Lemopoulos, Richard Marie Servajean, Simon Bernhard Otto

The bacterial type VI secretion system (T6SS) is a widespread, kin-discriminatory weapon capable of shaping microbial communities. Due to the system’s dependency on contact, cellular interactions can lead to either competition or kin protection. Cell-to-ce ...

Vertical distribution and seasonal dynamics of planktonic cyanobacteria communities in a water column of deep mesotrophic Lake Geneva

Tamar Kohn, Stéphane Joost, Anna Carratala Ripolles, Oliver Michele Selmoni, Charlotte Gisèle Weil, Hannah Elisa Chmiel, Annie Sandrine Guillaume, Coralie Chappelier

Background: Temperate subalpine lakes recovering from eutrophication in central Europe are experiencing harmful blooms due to the proliferation of Planktothrix rubescens, a potentially toxic cyanobacteria. To optimize the management of cyanobacteria blooms ...

Living Photovoltaics based on Recombinant Expression of MtrA Decaheme in Photosynthetic Bacteria

Ardemis Anoush Boghossian, Melania Reggente, Mohammed Mouhib, Alessandra Antonucci, Nils Schürgers, Sara Politi

At the center of microbial bioelectricity applications lies the critical need to express foreign heme proteins that are capable of redirecting the electron flux of the cell’s metabolism. This study presents bioengineered Synechocystis sp. PCC 6803 cells ca ...

Photobiology and metabolic interactions in the symbiotic jellyfish Cassiopea

Niclas Heidelberg Lyndby

The symbiont-bearing jellyfish Cassiopea live a benthic lifestyle, positioning themselves upside-down on sediments in shallow waters to allow their endosymbiotic algae to photosynthesize in the sunlight. Over the last decades Cassiopea has become increasin ...

Stress granules quantification on fixed and live cells

Francesco Stellacci, Romain Guiet, Xufeng Xu

The custom script was written based on Fiji for measuring the number or size of stress granules inside fixed cells (using a fixed threshold) or live cells (using a local maximum). It allows the batch image data processing for the study of the effects of di ...

Archaeal type IV pili stabilize Haloferax volcanii biofilms in flow

Alexandre Louis André Persat, Lorenzo Anton-Louis Talà, Pascal Damian Odermatt

Multicellular communities of contiguous cells attached to solid surfaces called biofilms represent a common microbial strategy to improve resilience in adverse environments.1-3 While bacterial biofilms have been under intense investigation, whether archaea ...
