Cover Story: Mars is currently considered relatively inhospitable due to its freezing temperatures, among other factors. Should life currently exist on the planet, it would likely consist of subsurface microorganisms capable of surviving and/or metabolizing at cold temperatures. Methanogens are found in a wide variety of environments on Earth, ranging from seafloor hydrothermal vents to arctic permafrost. Two non-psychrophilic species of methanogens, Methanobacterium formicicum and Methanothermobacter wolfeii, have been shown capable of active growth following long-term exposure (~4 years) to freezing temperatures.

Mucus: An Underestimated Gut Target for Environmental Pollutants and Food Additives

  • Kévin Gillois,
  • Mathilde Lévêque,
  • Vassilia Théodorou,
  • Hervé Robert and
  • Muriel Mercier-Bonin

Synthetic chemicals (environmental pollutants, food additives) are widely used for many industrial purposes and consumer-related applications, which implies, through manufactured products, diet, and environment, a repeated exposure of the general pop...

Chemical Elicitors of Antibiotic Biosynthesis in Actinomycetes

  • Anton P. Tyurin,
  • Vera A. Alferova and
  • Vladimir A. Korshun

Whole genome sequencing of actinomycetes has uncovered a new immense realm of microbial chemistry and biology. Most biosynthetic gene clusters present in genomes were found to remain “silent” under standard cultivation conditions. Some sm...

A Sensitive and Rapid Method to Determine the Adhesion Capacity of Probiotics and Pathogenic Microorganisms to Human Gastrointestinal Mucins

  • Bélinda Ringot-Destrez,
  • Zéa D’Alessandro,
  • Jean-Marie Lacroix,
  • Muriel Mercier-Bonin,
  • Renaud Léonard and
  • Catherine Robbe-Masselot

Mucus is the habitat for the microorganisms, bacteria and yeast that form the commensal flora. Mucins, the main macromolecules of mucus, and more specifically, the glycans that cover them, play essential roles in microbial gastrointestinal colonizati...

Comparing the Recombinant Protein Production Potential of Planktonic and Biofilm Cells

  • Alexandra Soares,
  • Luciana Calheiros Gomes and
  • Filipe José Mergulhão

Recombinant protein production in bacterial cells is commonly performed using planktonic cultures. However, the natural state for many bacteria is living in communities attached to surfaces forming biofilms. In this work, a flow cell system was used...
