“…It is directly related with the competition ability of hydrogen ions with metal ions for active sites on the biosorbent surface 20, 21 . Generally, metal biosorption involves complex mechanisms of ion exchange, chelation, adsorption by physical forces, and ion entrapment in inter and intra fi brillar capillaries and spaces of the cell structural network of a biosorbent 22 . FTIR analysis showed that Y. lipolytica has many functional groups such as hydroxyl, carboxyl, amide or amino groups involved in potential mechanisms of metal ion binding.…”

This study examined the biosorption process of Ni(II) and Zn(II) from an aqueous solution by dead biomass of Yarrowia lipolytica. Optimum biosorption conditions were determined as a function of pH, biomass dosage, contact time, and temperature. The biosorbent was characterized by FTIR, which indicated the participation of hydroxyl, carboxyl, amide and amine groups in the process of binding the metal ions. The results showed that the biosorption processes of both metal ions closely followed pseudo-second order kinetics. The equilibrium data of Ni(II) and Zn(II) ions at 20, 30 and 40 o C fi tted the Langmuir and Freundlich isotherm models. Langmuir isotherm provided a better fi t to the equilibrium data, with a maximum biosorption capacity of the Y. lipolytica biomass for Ni(II) and Zn(II) of 30.12 and 44.44 mg/g respectively. The calculated thermodynamic parameters demonstrated that the biosorption of Ni(II) and Zn(II) ions onto the Y. lipolytica was feasible, spontaneous and endothermic.

“…At this point the total removal of the metal is carried out. The results are coincident for tamarind Shell with 95% of remotion at 58˚C and 3 hours [22], for the adsorption of Cadmium(II) from aqueous solution on natural and oxidized corncob (40˚C and 5 days) [27], but this are different for the mandarin waste [25], Caladium bicolor (wild cocoyam) biomass [28], and Saccharomyces cerevisiae [29]. The increase in temperature increases the rate of removal of Chromium(VI) and decreases the contact time required for complete removal of the metal, to increase the redox reaction rate [22].…”

We studied the Chromium(VI) removal capacity in aqueous solution by the lemon shell, using the diphenylcarbazide method to evaluate the metal concentration. So, the highest biosorption of the metal (50 mg/L) occurs within 100 minutes, at pH of 1.0, and 28˚C. According to temperature, the highest removal was observed at 60˚C, in 11 minutes, when the metal (1 g/L) is completely adsorbed. At the analyzed concentrations of Cr(VI), lemon shell, showed excellent removal capacity, besides it removes efficiently the metal in situ (97.2% removal, 7 days of incubation, 5 g of biomass). After 1 hour of incubation the studied biomass reduces 1.0 g of Cr(VI) with the simultaneous production of Cr(III); so it can be used to eliminate it from industrial wastewater.

Cleanup of industrial effluents containing heavy metals: a new opportunity of valorising the biomass produced by brewing industry

Heavy metal pollution is a matter of concern in industrialised countries. Contrary to organic pollutants, heavy metals are not metabolically degraded. This fact has two main consequences: its bioremediation requires another strategy and heavy metals can be indefinitely recycled. Yeast cells of Saccharomyces cerevisiae are produced at high amounts as a by-product of brewing industry constituting a cheap raw ma-terial. In the present work, the possibility of valorising this type of biomass in the bioremediation of real industrial efflu-ents containing heavy metals is reviewed. Given the auto-aggregation capacity (flocculation) of brewing yeast cells, a fast and off-cost yeast separation is achieved after the treat-ment of metal-laden effluent, which reduces the costs associ-ated with the process. This is a critical issue when we are looking for an effective, eco-friendly, and low-cost technolo-gy. The possibility of the bioremediation of industrial effluents linked with the selective recovery of metals, in a strategy of simultaneous minimisation of environmental hazard of indus-trial wastes with financial benefits from reselling or recycling the metals, is discussed.
