“…Diniz and Voleksy [3] report 0.8-0.9 mmol Eu g −1 of Sargassum biomass for pH range 3-5, while Cadogan et al [28] report maximum monolayer sorption capacity of 114 and 3.2 mg g −1 by chitosan nanoparticles and crab shell powder, respectively. Maximum sorption capacity of Eu by crab shell particles at pH 6 was found to be 49.5 mg g −1 [29] and neodymium (an homolog of europium of same physicochemical properties) uptake lied between 10 and 12 mg g −1 by Candida colliculosa, Debaryomyces hansenii, and Kluyveromyces marxianus yeasts at pH 1.5 [2]. In the present study, under optimal conditions, Eu removal was found to be 37%, which corresponds to 8 mg Eu g −1 .…”

Exploitation of this phenomenon suggests the development of microbe-based remediation strategies to clean up metal-bearing waste streams and groundwaters and a potential use of micro-organisms, either in the treatment of radionuclides for reasons related to radioactive waste management or in the recovery of precious entities.…”

“…Europium and neodymium have been used as homologs of trivalent actinide elements, due to their similar physicochemical properties, in studies concerning the environmental behavior of the trivalent actinides [2]. Furthermore, considering the high cost of rare earth elements and the rapid growth of their applications such as in automotive catalytic converters, glass polishing and ceramics, petroleum refining, and electronics, studies of Eu (III) retention also aim at metal recovery for financial reasons [3,4].…”

A B S T R A C TThe Eu(III) uptake from aqueous solutions by Saccharomyces cerevisiae, Kluyveromyces marxianus, and Debaromyces hansenii was studied as a function of the growth temperature, supply of air flow during the cultivation process, and the age of cells. Our results revealed that exponential phase cells and the optimum temperature of growth resulted in a higher metal uptake, while aeration did not have any significant effect on the uptake. These traits make the proposed bisorbents desirable for clean-up processes due to easy access and low cost, as well as low time-and low energy-consuming optimal conditions as specified in this study. The reason why younger cells grown close to the optimal temperature show higher metal removal capacity is related to qualitative and quantitative alterations of their membranes' content in fatty acids and carboxyl groups mainly.

“…Exploitation of this phenomenon suggests a potential use of microorganisms, in the remediation of metal-containing waste waters (Volesky and Holan, 1995), in the recovery of precious entities, such as gold (Umali, et al, 2006), or in the treatment of radionuclides for reasons related to Radioactive Waste Management (Vlachou et al, 2009;Sarri et al, 2009). Diverse microorganisms, such as algae (Herrero et al, 2008;Lodeiro et al, 2006), fungi (Arica et al, 2001), bacteria (Ozdemir et al, 2004) and yeasts (Vlachou et al, 2009;Sarri et al, 2009), have been investigated, as an alternative way for removing toxic metals from aqueous solutions. Because some microorganisms may derive as by-products or even waste materials from industry or agriculture, are commonly considered as inexpensive biosorbents, like other naturally abundant materials (Carro et al, 2010;Hawari and Mulligan, 2006;McKey et al, 1999;Volesky 2003).…”

The dependence of Cd(II) and Cu(II) uptake by yeast cells on the age and temperature of cell culture was studied. Saccharomyces cerevisiae, Kluyveromyces marxianus and Debaromyces Hansenii were chosen as typical yeasts, while Cd(II) and Cu(II) as typical metal pollutants. Our results revealed that higher metal uptake was obtained by cells grown at the optimum temperature (30 o C) of cell culture. It was also found that the exponential phase cells resulted in a higher metal uptake than the stationary ones. A first interpretation of relevant bibliographic data concerning the effect of growth phase on metal uptake is proposed, assuming that limited qualitative changes in the cell wall structure take place as the cells pass from exponential to stationary phase, in addition to quantitative modifications, which have been reported in the literature. According to our interpretation the relative abundance among quantitative and qualitative alterations of cell wall, determines if stationary or exponential cells attain the higher metal binding capacity. An indication supporting our approach may be the fact that our hypothesis implies a decrease of pK a values of cell wall carboxyl groups with the age of cells, which is consistent with data reported by other authors. KEYWORDS: uptake, removal, Saccharomyces cerevisiae, Kluyveromyces marxianus, Debaromyces Hansenii, growth phase, growth temperature. INTRODUCTIONWater pollution, due to heavy metals, is a serious worldwide problem. Cadmium is a heavy metal, which poses serious health hazards through entry into the food chain (Vasudevan et al., 2003). Copper is another heavy metal with many industrial applications (Konstantinou and Pashalidis, 2008). Although it is an essential element, WHO has established a limit of 2 mg L -1 as the maximum acceptable concentration in drinking water. Aiming at removal of heavy metals, numerous attempts have been made to treat wastewaters by traditional methods such as, chemical precipitation, lime coagulation, ion-exchange, reverse osmosis, membrane separation, adsorption onto active carbon, e.t.c. However, all these methods have shown varying performances, often incomplete metal removal, especially in low concentration pollutant range, high energy requirements, high capital investment and operating costs (Grimm et al., 2008;Vázquez et al., 2009;Chojnacka and Michalak, 2009).
