Effects of metals on activity and community of sulfate-reducing bacterial enrichments and the discovery of a new heavy metal-resistant SRB from Santos Port sediment (São Paulo, Brazil)
(2022-01-01)
Sulfate-reducing bacteria (SRB) can be used to remove metals from wastewater, sewage, and contaminated areas. However, metals can be toxic to this group of bacteria. Sediments from port areas present abundance of SRB and ...
Metal sulfide precipitation: Recent breakthroughs and future outlooks
(MDPI, 2021)
The interest in metal sulfide precipitation has recently increased given its capacity to efficiently
recover several metals and metalloids from different aqueous sources, including wastewaters
and hydrometallurgical ...
Applications of bacterial cellulose as precursor of carbon and composites with metal oxide, metal sulfide and metal nanoparticles: A review of recent advances
(Elsevier, 2017-02)
This mini review is limited to very recent studies (last 5–10 years) on two major issues, concerning: the production and physical/chemical modification of bacterial cellulose (BC), and its transformation into carbon and ...
Appraisal of fiber-metal laminate panels reinforced with metal pins deposited by CMT welding
(2017-11-15)
Adhesion between metal and composite is key to fiber-metal laminates (FML). CMT (Cold Metal Transfer) welding has been used for hybrid joints that couple metal pin anchoring with adhesive bonding, but this concept has not ...
Antimicrobial Polymers with Metal Nanoparticles
(MDPI, 2015)
Metals, such as copper and silver, can be extremely toxic to bacteria at
exceptionally low concentrations. Because of this biocidal activity, metals have been
widely used as antimicrobial agents in a multitude of ...
Heavy metal availability in pelargonium hortorum rhizosphere: Interactions, uptake and plant accumulation
(Taylor & Francis, 2012-06)
The rhizosphere is a key area for the plant metal uptake. We studied heavy metal availability in the rhizosphere and the bulk soil, the interactions between metal ions, and their effects on heavy metal uptake and accumulation ...
2-Mercaptobenzothiazole clay as matrix for sorption and preconcentration of some heavy metals from aqueous solution
(1995-05-03)
2-Mercaptobenzothiazole loaded on previously polystyrene treated clay was prepared, characterized and used for sorption and preconcentration of Hg(II) Pb(II), Zn(II) and Cd(II) from an aqueous solution. The support used ...
Diversity and Distribution of Heavy Metal-Resistant Bacteria in Polluted Sediments of the Araça Bay, São Sebastião (SP), and the Relationship Between Heavy Metals and Organic Matter Concentrations
(2016-10-01)
Heavy metals influence the population size, diversity, and metabolic activity of bacteria. In turn, bacteria can develop heavy metal resistance mechanisms, and this can be used in bioremediation of contaminated areas. The ...
Heavy metal resistance strategies of acidophilic bacteria and their acquisition: Importance for biomining and bioremediation
(2013)
Microbial solubilizing of metals in acid environments is successfully used in industrial bioleaching of ores or biomining to extract metals such as copper, gold, uranium and others. This is done mainly by acidophilic and ...
