Biosorption of precious metals
Biotechnology Advances, 2007Biosorption has emerged as a low-cost and often low-tech option for removal or recovery of base metals from aqueous wastes. The conditions under which precious metals such as gold, platinum and palladium are sorbed by biomass are often very different to those under which base metals are sorbed.

Biotechnology Progress, 1995
AbstractOnly within the past decade has the potential of metal biosorption by biomass materials been well established. For economic reasons, of particular interest are abundant biomass types generated as a waste byproduct of large‐scale industrial fermentations or certain metal‐binding algae found in large quantities in the sea.

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 mechanism of cobalt biosorption
Biotechnology and Bioengineering, 1989AbstractNonliving biomass of the common seaweed Ascophyllum nodosum is capable of accumulating cobalt from aqueous solutions to the extent of 160 mg Co2+/g. Successful desorption of cobalt from the biomass by acidic CaCl2 solutions revealed that the metal uptake phenomenon is reversible, implying physical sorption of cobalt.

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.

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 chromium by Termitomyces clypeatus
Colloids and Surfaces B: Biointerfaces, 2007The manuscript describes removal of chromium from aqueous solution by biomass of different moulds and yeasts. The biomass of Termitomyces clypeatus (TCB) is found to be the most effective of all the fungal species tested. The sorption of hexavalent chromium by live TCB depends on the pH of the solution, the optimum pH value being 3.0.

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.

Biosorption of Radionuclides by Fungal Biomass
Journal of Chemical Technology & Biotechnology, 1990AbstractFour kinds of bioreactor were evaluated for thorium removal by fungal biomass. Static‐bed or stirred‐bed bioreactors did not give satisfactory thorium removal probably because of poor mixing. An air‐lift bioreactor removed approximately 90–95% of the thorium supplied over extended time periods and exhibited a well‐defined breakthrough point ...

Biosorption with Algae: A Statistical Review
Critical Reviews in Biotechnology, 2006The state of the art in the field of biosorption using algae as biomass is reviewed. The available data of maximum sorption uptake (qmax) and biomass-metal affinity (b) for Cd2 +, Cu2 +, Ni2 +, Pb2 + and Zn2 + were statistically analyzed using 37 different algae (20 brown algae, 9 red algae and 8 green algae).
