Identifier les fonctionnalités des communautés bactériennes du sol. En direct des labos
2007
; Les chercheurs ont mis au point une méthode d’extraction et d’analyse des protéines générées par le métabolisme cellulaire des bactéries du sol (metaprotéome) pour caractériser in situ et sans a priori la structure fonctionnelle et la fonctionnalité des communautés microbiennes indigènes.
Gut Bacteria Metabolism Impacts Immune Recovery in HIV-infected Individuals.
2016
While changes in gut microbial populations have been described in human immuno-deficiency virus (HIV)-infected patients undergoing antiretroviral therapy (ART), the mechanisms underlying the contributions of gut bacteria and their molecular agents (metabolites and proteins) to immune recovery remain unexplored. To study this, we examined the active fraction of the gut microbiome, through examining protein synthesis and accumulation of metabolites inside gut bacteria and in the bloodstream, in 8 healthy controls and 29 HIV-infected individuals (6 being longitudinally studied). We found that HIV infection is associated to dramatic changes in the active set of gut bacteria simultaneously alter…
Protein and DNA fingerprinting of a soil bacterial community inoculated into three different sterile soils
2007
The functional and genetic structures of a soil bacterial community were characterized after inoculation into three different sterile soils using a protein and DNA fingerprinting method, respectively. Principal component analysis (PCA) of profiles revealed that, depending on soil characteristics, bacterial communities with similar genetic structures harbored different functional structures and thus could potentially be of differing ecological significance for soil functioning. Co-inertia analysis between protein fingerprinting data and the corresponding sets of soil physicochemical characteristics demonstrated the correlation between the functional structure of the bacterial community and s…
