Denitrification in pathogenic bacteria : for better or worst ?
2005
A large variety of physiological and taxonomic groups have the ability to use nitrogen oxides as alternative electron acceptors. Brucella spp. is an alpha-proteobacteriaceae that induces a persistent disease in some mammals. Recent work has revealed that a denitrifying gene cluster is important in the interaction of Brucella neotomoae with its host.

Les confiscacions de béns als austriacistes de Dénia. Una primera aproximació.
2007
Lopez Camps, Joaquin Enrique - Joaquim.Lopez@uv.es La caiguda de Dénia en mans de les tropes borbòniques el novembre de 1708 va afavorir el desplegament d'un procés de confiscació dels béns dels austriacistes de la ciutat amb el qual es pretenia incrementar els ingressos de la Corona i compensar la fidelitat dels borbònics valencians. No obstant, la despoblació quasi completa de la ciutat i la paralització de les activitats econòmiques va dificultar extraordinàriament aquest procés. L'article analitza quantitativa i qualitativament el procés confiscatori a Dénia i mostra les dificultats que la política de segrest dels béns dels austriacistes va tenir en el conjunt del País Valencià.
Loss in microbial diversity affects nitrogen cycling in soil
2013
International audience; Microbial communities have a central role in ecosystem processes by driving the Earth's biogeochemical cycles. However, the importance of microbial diversity for ecosystem functioning is still debated. Here, we experimentally manipulated the soil microbial community using a dilution approach to analyze the functional consequences of diversity loss. A trait-centered approach was embraced using the denitrifiers as model guild due to their role in nitrogen cycling, a major ecosystem service. How various diversity metrics related to richness, eveness and phylogenetic diversity of the soil denitrifier community were affected by the removal experiment was assessed by 454 s…

Ecology of N2O reducing bacteria in arable soils
2016
Nitrous oxide (N2O) is an important greenhouse gas (GHG) and the main ozone depleting substance. Agricultural soils are the main anthropogenic-induced source of this GHG. The concentration of N2O in the atmosphere is steadily increasing, but we still lack knowledge on the factors controlling its production and consumption in soils. The reduction of N2O to N2 by microorganisms harboring the N2O reductase gene (nosZ) is the only known biological process able to consume this GHG. Recent studies revealed a previously unknown clade of N2O-reducers which was shown to be important to the N2O sink capacity of soils. This thesis seeks to gain a greater understanding on the ecology of N2O-reducers in…
