Legumes form a large group of plants that constitute the third largest family of angiosperms,
including near 20,000 species and 750 genera. Most of them have the ability to establish …

The need for sustainable agricultural practices is revitalizing the interest in biological
nitrogen fixation and rhizobia-legumes symbioses, particularly those involving economically …

Lithotrophic sulfur oxidation is an ancient metabolic process. Ecologically and taxonomically
diverged prokaryotes have differential abilities to utilize different reduced sulfur compounds …

The taxonomy of rhizobia, bacteria capable of nodulating leguminous plants, has changed
considerably over the last 20 years, with the original genus Rhizobium, a member of the …

Symbiotic nitrogen fixation is the main route for sustainable input of nitrogen into
ecosystems. Nitrogen fixation in agriculture can be improved by inoculation of legume crops …

The Rhizobia are collectively comprised of gram negative soil bacteria that have the ability
to form symbiotic nitrogen-fixing root and/or stem nodules in association with leguminous …

Sulfur (S) deficiency in soils is becoming increasingly common in many areas of the world as
a result of agronomic practices, high biomass exportation and reduced S emissions to the …

Background Biogenic sulfuric acid (BSA) corrosion damages sewerage and wastewater
treatment facilities but is not well investigated in sludge digesters. Sulfur/sulfide oxidizing …

A polyphasic taxonomic approach was used to characterize 31 rhizobial isolates obtained
from Anthyllis vulneraria, a metallicolous legume species, growing close to a zinc mine in …

Sulfur (S) is a macro-element required for life. S deficiency limits plant growth.
Microorganisms carry out several essential steps in the recycling of organic and inorganic S …
