Isolation Of Tellurite And Seleniteresistant Bacteria

Deep-ocean hydrothermal-vent environments are rich in heavy metals and metalloids and present excellent sites for the isolation of metal-resistant microorganisms.Both metalloid-oxide-resistant and metalloid-oxide-reducing bacteria were found.Tellurite- and selenite-reducing strains were isolated in high numbers from ocean water near hydrothermal vents, bacterial films, and sulfide-rich rocks.

Metal Fractionation In Soils And Assessment

Extraction procedure.A modification of the three step bcr sequential extraction method described by tokalioglu et al.2010 was applied to 1 g of soil in duplicate.The main modification with respect to tokalioglu et al.2010 was that the final extraction step used 7.5 n hno 3, rather than aqua regia.This is an important difference if one cares about the chemically immobile silicate-bound.

Water system degradation has a severe impact on daily life, especially in developing countries.However, microbial changes associated with this degradation, especially changes in microbes related to sulfur s cycling, are poorly understood.In this study, the abundance, structure, and diversity of sulfate-reducing microorganisms srm and sulfur-oxidizing microorganisms som in the sediments.

16s Rrna Gene Amplicon Based Metagenomic

Rice is a major staple food across the globe.Its growth and productivity is highly dependent on the rhizobiome where crosstalk takes place between plant and the microbial community.Such interactions lead to selective enrichment of plant beneficial microbes which ultimately defines the crop health and productivity.In this study, rhizobiome modulation is documented throughout the development.
