Project description:Pregnant C3H mice were given tap water (control group) and tap water containing 85 ppm sodium arsenite from gestational day 8 to 18 (arsenic group), respectively. The DNA methylomes of sperm of F1 mice were investigated by RRBS method. The results showed that gestational arsenic exposure increased hypomethylated cytosines in active retrotransposon subfamilies. The present study has indicated environmental impacts on sperm DNA methylome establishment.

Project description:Tor Caldara is a shallow-water gas vent located in the Mediterranean Sea, with active venting of CO 2 , H 2 S. At Tor Caldara, filamentous microbial biofilms, mainly composed of Epsilon- and Gammaproteobacteria, grow on substrates exposed to the gas venting. In this study, we took a metaproteogenomic approach to identify the metabolic potential and in situ expression of central metabolic pathways at two stages of biofilm maturation. Our findings indicate that inorganic reduced sulfur species are the main electron donors and CO 2 the main carbon source for the filamentous biofilms, which conserve energy by oxygen and nitrate respiration, fix dinitrogen gas and detoxify heavy metals. Three metagenome-assembled genomes (MAGs), representative of key members in the biofilm community, were also recovered. Metaproteomic data show that metabolically active chemoautotrophic sulfide-oxidizing members of the Epsilonproteobacteria dominated the young microbial biofilms, while Gammaproteobacteria become prevalent in the established community. The co-expression of different pathways for sulfide oxidation by these two classes of bacteria suggests exposure to different sulfide concentrations within the biofilms, as well as fine-tuned adaptations of the enzymatic complexes. Taken together, our findings demonstrate a shift in the taxonomic composition and associated metabolic activity of these biofilms in the course of the colonization process.

Project description:In this study we examined an anaerobic digester reactor fed with cellulose in order to identify cellulose degrading microorganisms using a culture independent approach. A metagenome was linked to the newly synthesized proteins involved by cellulose, by investigation of labelled proteins (Protein-SIP). The study aims at identifying microorganisms involved in the degradation of plant-based biomass.
