Article Synopsis
- The study focuses on the role of the LytSR two-component regulatory system (TCS) in the virulence of a coagulase-negative staphylococcus, especially in biofilm-related infections.
- Deleting the LytSR system led to decreased biofilm formation, characterized by lower biomass and increased dead cells, and significantly reduced virulence in a slow-killing assay.
- The results indicate that LytSR influences the expression of 286 genes related to metabolism and virulence factors, highlighting its importance in bacterial pathogenesis.
Low impact of phenanthrene dissipation on the bacterial community in grassland soil.
Environ Sci Pollut Res Int
February 2014
The effect of phenanthrene on the bacterial community was studied on permanent grassland soil historically presenting low contamination (i.e. less than 1 mg kg(-1)) by polycyclic aromatic hydrocarbons (PAHs).

In order to estimate the bioremediation potentials and to identify the bacterial species involved in hydrocarbon degradation, we used microcosms containing seawater from the Seine estuary supplemented with either naphthalene, phenanthrene, fluorene or pyrene. In the microcosms enriched with naphthalene or phenanthrene, hydrocarbon biodegradation was significant within 9 weeks (43% or 46%, respectively), as shown by analyses in GC-MS.
