This work investigates the possible usage of edible mushrooms as support for metabolic quantities of copper. Biosorption potential of natural and biodegradable matrix formed from wild Lactarius piperatus mushrooms, in suspension (LP) and alginate immobilized based beads (LPAB), was explored. The effects of biomass quantity, Cu(II) concentration, and temperature were assessed. LPAB showed better adsorption capacity (7.67 mg/g) by comparison to LP biosorbent (6.43 mg/g). Also, biosorption efficiencies up to 76 and 99 % for LP and LPAB (for the same quantity of biomass, 2 g), respectively, were obtained. Furthermore, a multilayer feed forward Artificial Neural Network (ANN) model was developed in order to predict the biosorption efficiency. The trained ANNs, for LP and LAPB biosorbents, showed good correlation (R = 0.998) between the predicted and experimental biosorption efficiency, associated to reduced mean relative errors and demonstrated that the ANN has a good generalization potential. 1–2 g of Lactarius piperatus mushroom, as powder or in alginate‐based beads containing Cu(II), could be used as a dietary supplement in order to supply the daily copper demand of the organism.

A B S T R A C TThere is a great interest in the removal of heavy metals from aqueous media by various biomass. In this study, the potential of using live and dead cells of Variovorax paradoxus and Arthrobacter viscosus bacteria for the removal of Zn(II) were investigated for the first time. The bacteria were isolated from the ceramic industry sludge. Remaining concentrations of Zn(II) in the metal solutions after biosorption by bacteria were measured by ICP-OES. The removal of Zn(II) from aqueous solution increased with increasing pH and initial ion concentration. The maximum removal efficiency of V. paradoxus live and dead cells was calculated as 92.7 and 91.3%, respectively, whereas the maximum removal efficiency of A. viscosus live and dead cells was calculated as 89.4 and 90.8%, respectively. The experimental data was found to comply with the Freundlich isotherm model and the biosorption mechanism was expressed with the pseudo-second-order model.

Algae biosorption is an ideal wastewater treatment method when coupled with algae growth and biosorption. The adsorption and bioaccumulation of strontium from simulated nuclear wastewater by Scenedesmus spinosus were investigated in this research. One hundred mL of cultured S. spinosus cells with a dry weight of 1.0 mg in simulated nuclear wastewater were used to analyze the effects on S. spinosus cell growth as well as the adsorption and bioaccumulation characters under conditions of 25 ± 1 °C with approximately 3,000 lux illumination. The results showed that S. spinosus had a highly selective biosorption capacity for strontium, with a maximum bioremoval ratio of 76%. The adsorbed strontium ion on cell walls was approximately 90% of the total adsorbed amount; the bioaccumulation in the cytoplasm varied by approximately10%. The adsorption quantity could be described with an equilibrium isotherm. The pseudo-second-order kinetic model suggested that adsorption was the rate-limiting step of the biosorption process. A new bioaccumulation model with three parameters was proposed and could give a good fit with the experiment data. The results suggested that S. spinosus may be a potential biosorbent for the treatment of nuclear wastewater in culture conditions.
