Genomic insights into the coupling of a Chlorella-like microeukaryote and sulfur bacteria in the chemocline of permanently stratified Lake Cadagno

Meromictic Lake Cadagno is a permanently stratified system with a persistent microbial bloom within the oxic-anoxic boundary called the chemocline. The association between oxygenic and anoxygenic photosynthesis within the chemocline has been known for at l ...

Microbes support enhanced nitrogen requirements of coral holobionts in a high CO 2 environment

Nils Rädecker, Gabriela Hannah Holligan Perna

Ocean acidification is posing a threat to calcifying organisms due to the increased energy requirements of calcification under high CO2 conditions. The ability of scleractinian corals to cope with future ocean conditions will thus depend on their ability t ...

Single-cell studies of Mycobacterium smegmatis cell cycle using time-lapse fluorescence microscopy

Joëlle Xiao Yuan Ven

Cell division is one of the most primordial cellular processes and is essential for life propagation. It is composed of crucial events, namely genome duplication, chromosomes segregation and membrane separation. Failure of these processes will have dramati ...

Ecological implications of gene regulation by TfoX and TfoY among diverse Vibrio species

Melanie Blokesch, Candice Stoudmann, Noémie Matthey, Lisa Christina Metzger, Esther Jeanne Collas

Bacteria of the genus Vibrio are common members of aquatic environments where they compete with other prokaryotes and defend themselves against grazing predators. A macromolecular protein complex called the type VI secretion system (T6SS) is used for both ...

Molecular phylogeny suggests transfer of Hemidiscus into Actinocyclus (Coscinodiscales, Coscinodiscophyceae)

Lu Wang

Hemidiscus cuneiformis, type of the family Hemidiscaceae, is a diatom with a distinctive semi-circular shape in valve view. A strain of H. cuneiformis was established from the coastal region of the tropical southwestern Atlantic Ocean off Brazil. Cells of ...

Chemometric Analysis of Bacterial Peptidoglycan Reveals Atypical Modifications That Empower the Cell Wall against Predatory Enzymes and Fly Innate Immunity

Bruno Lemaitre

Peptidoglycan is a fundamental structure for most bacteria. It contributes to the cell morphology and provides cell wall integrity against environmental insults. While several studies have reported a significant degree of variability in the chemical compos ...

Indirect evidences for PCB congener degradation by Geobacteraceae in anaerobic sediment-free microcosms

Christof Holliger, Pierre Rossi, Luiz Felippe De Alencastro, Martina Praveckova

Although PCBs production was brought to a halt thirty years ago, recalcitrance to degradation makes them a major environmental pollutant. Previous studies confirmed that organohalide-respiring bacteria (OHRB) were capable of utilizing chlorinated congeners ...

The mitochondrial unfolded protein response in mammalian physiology

Johan Auwerx, Adrienne Joëlle Laurence Mottis, Virginija Jovaisaite

Mitochondria, the main site of cellular energy harvesting, are derived from proteobacteria that evolved within our cells in endosymbiosis. Mitochondria retained vestiges of their proteobacterial genome, the circular mitochondrial DNA, which encodes 13 subu ...

An experimental model approach of biologically-assisted silicate dissolution with olivine and Escherichia coli - Impact on chemical weathering of mafic rocks and atmospheric CO2 drawdown

Philippe Gillet, Bruno Garcia

Chemical weathering of Mg, Ca-silicates and alumino-silicates contributes significantly to the drawdown of atmospheric CO2 over long time scales. The present work focuses on how this mode of weathering may change in the presence of free-living bacteria in ...

Comparative 16S rDNA and 16S rRNA sequence analysis indicates that Actinobacteria might be a dominant part of the metabolically active bacteria in heavy metal-contaminated bulk and rhizosphere soil

Fabienne Gremion

Bacterial diversity in 16S ribosomal DNA and reverse-transcribed 16S rRNA clone libraries originating from the heavy metal-contaminated rhizosphere of the metal-hyperaccumulating plant Thlaspi caerulescens was analysed and compared with that of contaminate ...
