Microbial hydrogen sinks in the sand-bentonite backfill material for the deep geological disposal of radioactive waste

Rizlan Bernier-Latmani, Manon Frutschi, Nicolas Louis Maurice Jacquemin, Simiao Wang, Camille Aude Rolland, Niels Burzan, Aislinn Ann Boylan

The activity of subsurface microorganisms can be harnessed for engineering projects. For instance, the Swiss radioactive waste repository design can take advantage of indigenous microorganisms to tackle the issue of a hydrogen gas (H2) phase pressure build ...

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 ...

Modeling, analysis, and design of complex biological networks

Mohammadomid Oftadeh

Automating experimental procedures has resulted in an unprecedented increase in the volume of generated data, which, in turn, has caused an accumulation of unprocessed data. As a result, the need to develop tools to analyze data systematically has been ris ...

Active anaerobic methane oxidation and sulfur disproportionation in the deep terrestrial subsurface

Rizlan Bernier-Latmani, Manon Frutschi, Emma Bell, Chen Qian

Microbial life is widespread in the terrestrial subsurface and present down to several kilometers depth, but the energy sources that fuel metabolism in deep oligotrophic and anoxic environments remain unclear. In the deep crystalline bedrock of the Fennosc ...

Functional and structural characterization of Serratia marcescens ExbB: determinants of the interaction with HasB/TonB

Henning Paul-Julius Stahlberg

ExbBD is part of a cytoplasmic membrane molecular motor driven by the proton-motive force. It belongs to the larger family of motors involved in nutriment import across the outer membrane of Gram-negative bacteria (ExbBD), flagellar rotation (MotAB) or lat ...

Coordination-Driven Monolayer-to-Bilayer Transition in Two-Dimensional Metal–Organic Networks

Henning Paul-Julius Stahlberg, Mina Moradi, Patrick Shahgaldian

We report on monolayer-to-bilayer transitions in 2D metal–organic networks (MONs) from amphiphiles supported at the water–air interface. Functionalized calix[4]arenes are assembled through the coordination of selected transition metal ions to yield monomol ...

Methylation of arsenic by single-species and soil-derived microbial cultures

Karen Elda Viacava Romo

Arsenic (As) is simultaneously a ubiquitous and a toxic element. Arsenic is subject to bio-transformations catalyzed by microorganisms constituting the As biogeochemical cycle. The primordial Earth was devoid of oxygen, exposing life to the highly mobile a ...

Engineering of ecological niches to create stable artificial consortia for complex biotransformations

Jeremy Luterbacher

The design of controllable artificial microbial consortia has attracted considerable interest in recent years to capitalize on the inherent advantages in comparison to monocultures such as the distribution of the metabolic burden by division of labor, the ...

OsCAldOMT1 is a bifunctional O-methyltransferase involved in the biosynthesis of tricin-lignins in rice cell walls

Wu Lan

Lignin is a phenylpropanoid polymer produced in the secondary cell walls of vascular plants. Although most eudicot and gymnosperm species generate lignins solely via polymerization of p-hydroxycinnamyl alcohols (monolignols), grasses additionally use a fla ...

A Simple, Robust, and Low-Cost Method To Produce the PURE Cell Free System

Sebastian Maerkl, Barbora Lavickova

We demonstrate a simple, robust, and low-cost method for producing the PURE cell-free transcription translation system. Our OnePot PURE system achieved a protein synthesis yield of 156 peg/mL at a cost of 0.09 USD/ktL, leading to a 14-fold improvement in c ...
