Microbial ecology of hot desert edaphic systems.
This review examines the microbial communities of hot desert terrestrial biotopes (including soils, cryptic and refuge niches and plant-root-associated microbes) and the processes that govern their assembly and the possible effects of global climate change on hot desert microbial communities and the resulting feedback mechanisms.

Herbaspirillum lusitanum sp. nov., a novel nitrogen-fixing bacterium associated with root nodules of Phaseolus vulgaris.
The complete 16S rDNA sequence of a representative strain was obtained and phylogenetic analysis based on the neighbour-joining method indicated that this bacterium belongs to the beta-Proteobacteria and that the closest related genus is Herbaspirillum. Expand
Phyllobacterium trifolii sp. nov., nodulating Trifolium and Lupinus in Spanish soils.
The results of DNA-DNA hybridization, phenotypic tests and fatty acid analyses confirmed that this strain represents a novel species of the genus Phyllobacterium, for which the name PhyllOBacterium trifolii sp. Expand
Abundance, diversity and prospecting of culturable phosphate solubilizing bacteria on soils under crop–pasture rotations in a no-tillage regime in Uruguay
Phosphate solubilizing bacteria (PSB) abundance and diversity were examined during two consecutive years, 2007 and 2008, in a crop/pasture rotation experiment in Uruguay and no differences were found in PSB abundance or diversity. Expand
Rhizobium lusitanum sp. nov. a bacterium that nodulates Phaseolus vulgaris.
The results of DNA-DNA hybridization and phylogenetic analysis showed that the strains isolated in this study belong to a novel species of the genus Rhizobium, for which the name RhizOBium lusitanum sp. Expand
Correlation among soil enzyme activities under different forest system management practices
Abstract Soil enzyme activities were performed in three permanent no-till and unfertilised plots located in the South of Salamanca province (Spain), the first in a Castanea sativa Mill. paraclimaxExpand
Lactococcus lactis subsp. tructae subsp. nov. isolated from the intestinal mucus of brown trout (Salmo trutta) and rainbow trout (Oncorhynchus mykiss).
Three strains, designated L105(T), I3 and L101, were isolated from the intestinal mucus of brown trout and rainbow trout and represent a new subspecies, for which the name Lactococcus lactis subsp. Expand
Phosphate-solubilizing bacteria as inoculants for agriculture: use of updated molecular techniques in their study
Une methode d'isolation de souches efficientes pour the solubilisation du phosphate and une methode pour obtenir des sondes d'ADN specifiques des souches d'un equipement sophistique are presente. Expand
Diversity and activity of phosphate bioleaching bacteria from a high-phosphorus iron ore
Many of the current world iron ore resources contain over 0.08 w% of P, making this material out-of-standard for the manufacture of metallic iron and steel. Solubilization of phosphatic minerals canExpand
Mobilization of phosphorus from iron ore by the bacterium Burkholderia caribensis FeGL03
The bacterium Burkholderia caribensis FeGL03, isolated from a Brazilian high-phosphorus iron ore, was used to mobilize the phosphate contained in the same ore. The phosphate-mobilizing ability of theExpand
