Immobilized microbial nanoparticles for biosorption
Critical Reviews in Biotechnology, 2020Biosorption processes emerge as an economical and eco-friendly alternative technology for the removal of pollutants present in the environment. One biosorption process application is found in the immobilization of microbial cells for the removal of toxic pollutants in industrial wastewater.

Highlighting inconsistencies regarding metal biosorption
Journal of Hazardous Materials, 2016Thousands of articles have been devoted to examine different types of biosorbents and their use in cleaning polluted waters. An important objective of some studies has been the identification of the biosorption mechanisms. This type of investigation is not always performed, as it can only be done if scientists are aware of all mechanisms that, at least

Biosorption of Mercury by Microorganisms
Acta Biotechnologica, 1984AbstractBiomasses are able to sorb great amounts of mercury ions from water solutions.Sorbed concentrations are dependent on the pH‐value, the strain of microorganisms and the substrate used for cultivation.The uptake of mercury takes place at a high reaction rate and is completed after few minutes.

Biosorption is a unique ability of living or dead biomass to interact with substances such as metals where reduction of sorbate concentration can be achieved. Thus, it has been widely proposed as a promising alternative for metal remediation and recovery owing to its low cost and sustainable “green” nature.

There are many interactions between living cells and metals. Essential metals must he taken up by the cells, and they must be stored at their destinations. When the metals are present in the medium in too low a concentration, they must be accumulated. If the ambient metal concentration is too high, even essential metals become toxic and mechanisms of ...

Biosorption of Metal Ions on Arthrobacter sp.: Biomass Characterization and Biosorption Modeling
Environmental Science & Technology, 2000A culture of Arthrobacter sp. was tested for its ability to sorb copper, cadmium, and iron ions, and chemical modeling of experimental data was used to interpret the mechanism of biosorption. The purpose of the initial phase was to clarify the nature and concentration of active acidic sites on cell wall with the aid of potentiometric titration of an ...

Biosorption of copper by yeasts
Biology of Metals, 1991The ability to accumulate copper from aqueous solutions was determined with different yeast species. Yeast cells did not show any significant differences in process kinetics. The uptake was very fast and was influenced by environmental factors. The metal-accumulating capacity differed among the tested strains.

The ability of microorganisms to remove metal ions from dilute aqueous solutions is a widely studied phenomenon. Numerous applications of biosorption, mainly in laboratory or in pilot-scale, but recently also industrially, make often use of non-living biomass, which does not require supply of nutrients and can be exposed to environments of high ...

Biosorption: Application Strategies
2010Over the past few years, intensifying research into metal biosorption elucidated the principles of this effective metal removal phenomenon. Biosorption can be cost-effective, particularly in environmental applications where low cost of the metal removal process is most desirable.

Biosorption of Rare Earth Elements
Mineral Processing and Extractive Metallurgy Review, 1998Abstract By using X-ray microanalysis, the mechanism of sorption of rare earth elements (REE) and their localization in cells of Candida utilis were found to depend on the metal ion speciation in solution, the permeability of the cytoplasmic membrane (CPM), and elemental composition of cells.
