Mesorhizobium metallidurans STM 2683(T) is a nitrogen-fixing bacterium that nodulates Anthyllis vulneraria in mine tailings highly contaminated in zinc, lead and cadmium. To study the mechanisms whereby this bacterium copes with metals, we functionally screened a cosmid genomic library of M. metallidurans for zinc or cadmium tolerance. A cosmid clo...
The Titicaca Lake is the most important water resource over the Andean plateau and the ecological equilibrium of this region is nowadays perturbed by recent changes in land use and management practices. The Katari watershed encompasses mining area, cities representing over 1.2 million habitants, and agricultural zones before ending in Cohana bay in...
Multidrug resistance, which is acquired by both Gram-positive and Gram-negative bacteria, causes infections that are associated with significant morbidity and mortality in many clinical settings around the world. Because of the rapidly increasing incidence of pathogens that have become resistant to all or nearly all available antibiotics, there is ...

A novel heterogeneous respirometer for in situ assessment of the biological activity and mass transport phenomena of biofilm developed on packing materials of gas-phase biological filters is presented. The flexible respirometer configuration allows reproducing the operational features of biofilters and biotrickling filters to obtain reliable diagno...
The genera Agrobacterium, Allorhizobium, and Rhizobium belong to the family Rhizobiaceae. However, theplacement of a phytopathogenic group of bacteria, the genus Agrobacterium, among the nitrogen-fixingbacteria and the unclear position of Rhizobium galegae have caused controversy in previous taxonomicstudies. To resolve uncertainties in the taxonom...
While considered as sustainable and low-cost agricultural amendments, the impacts of organic fertilizers on downstream aquatic microbial communities remain poorly documented. We investigated the quantity and quality of the dissolved organic matter leaching from agricultural soil amended with compost, vermicompost or biochar and assessed their effec...
