1. Regulatory roles of sRNAs in pathogenesis of Vibrio cholerae
Abstract : The Gram-negative pathogen Vibrio cholerae uses variety of regulatory molecules to modulate expression of virulence factors. One important regulatory element of microorganisms is small non-coding RNAs (sRNAs), which control various cell functions such as expression of cell membrane proteins, mRNA decay and riboswitches.

2. Adhesion-related interactions of Actinomyces and Streptococcus biofilm bacteria
Abstract : Adhesion of bacteria is a key event in biofilm formation and is mediated by bacterial adhesins recognising host or bacterial partner receptors. In oral biofilm formation, primary Actinomyces and Streptococcus colonizers adhere to salivary pellicle proteins such as proline-rich proteins (PRPs) as well as to mucosal surfaces. READ MORE

3. Evolutionary trajectories of Klebsiella pneumoniae : From experimental biofilm evolution to a hospital outbreak
Abstract : Bacterial evolution is closely intertwined with our lives. As their hosts, we shape how bacteria evolve by imposing numerous selective pressures during the time bacteria spend in our bodies. As a result, they adapt in various ways to colonize us or infect us better. READ MORE

4. 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.

5. Prevention of Biofilm Formation on Silicone Rubber Materials for Outdoor High Voltage Insulators
Abstract : Microbial colonization on the surface of silicone rubber high voltage outdoor insulators often results in the formation of highly hydrated biofilm that influence the surface properties, such as surface hydrophobicity. The loss of hydrophobicity might lead to dry band formation, and, in the worst cases, flashover and failure of the insulator. READ MORE
