Project description:Microorganisms are key contributors to biogeochemical flux in estuarine ecosystems. In this study, we conducted proteogenomic characterization of microbial communities from estuarine ecosystems.
Project description:CdSe nanoparticles (CdSe NPs) are extensively used in the industry of renewable energies and it is regrettably expectedthat these pollutants will sometime soon appear in marine environmentthrough surface runoff, urban effluents and rivers. Bacteria living in estuarine and coastal sediments will be among the first targets of these new pollutants. The pseudomonads are frequently encountered in these ecosystems. They are involved in several biogeochemical cycles and are known for their high resistance to pollutants. Consequently, this study focussing on the effect of CdSe NPs on the marine strain P. fluorescensBA3SM1 is highly relevant for a number of reasons. First, it aims at improving knowledge about the interactions between bacteria and NPs. This is fundamental to use effectively NPs against pathogenic bacteria. Secondly, this study shows that CdSe NPs of 8 nm in diameter cause a decrease in the secretion of siderophorepyoverdine, a secondary metabolite having a key role in microbial ecology and also employed as a virulence factor in human pathogenic strains such as P. aeruginosa. Consequently, this study highlights that CdSe NPs can have an impact on secondary metabolism of bacteria with environmental and medical implications.
Project description:MicroRNAs (miRNAs) function as regulators in a broad range of phenotypes. The Oriental River Prawn (Macrobrachium nipponense) is an important commercial species that is widely distributed in freshwater and low-salinity estuarine regions of China and other Asian countries. To date, there are no reports describing M. nipponense miRNAs.

Project description:Proteomics of livers from Platichthys flesus after encagement in different estuarine sites for describing key molecular players in response to environmental stresses.
Project description:The great tit is a widely studied passerine bird species in ecology that, in the past decades, has provided important insights into speciation, phenology, behavior and microevolution. After completion of the great tit genome sequence, a customized high density 650k SNP array was developed enabling more detailed genomic studies in this species.
