1. Microbial biofilm communities associated with degradation of sprayed concrete in subsea tunnels
Abstract : Deterioration of concrete leads to reduced structural strength implying high societal challenge with huge economic impact. In the Oslofjord subsea tunnel, complex microbial biofilm activity together with abiotic attack from saline groundwater are responsible for concrete matrix degradation and steel fiber corrosion.

2. Microbially induced concrete degradation in subsea tunnels - Community structure of biofilms from sprayed reinforced concrete in the Oslofjord tunnel
Abstract : Microbially induced concrete deterioration has been discovered in several Norwegian subsea tunnels with significant disintegration of the calcium silicate hydrate (C-S-H) and steel fibre corrosion in areas with leakages of saline groundwater. Complex microbial biofilm activity together with abiotic attack from saline ground water, with high concentrations of Cl−, SO42−, Mg2+ and HCO3−, are responsible for the degradation in the specific subsea tunnel environment.

3. The interplay between bile acids and gut microbiota in metabolic and hepatobiliary disease
Abstract : The gut microbiota, a metabolic regulator, orchestrates the production of bioactive metabolites such as secondary bile acids. Growing evidence suggests that shifts in the gut microbiota composition are linked to metabolic and hepatobiliary disease. READ MORE

4. Microbial modulation of metabolic diseases
Abstract : The gut microbiota, the ensemble of microorganisms living in the gastrointestinal tract, and the host have a mutualist relationship. Alterations of this delicate equilibrium can lead to changes in microbiota composition and/or function leading to the onset of metabolic diseases (e.g., type 2 diabetes and non-alcoholic fatty liver diseases).
