Journal ArticleDOI
Rhizobacteria and plant symbiosis in heavy metal uptake and its implications for soil bioremediation.
Dana Luminita Sobariu,Daniela Ionela Fertu,Mariana Diaconu,Lucian Vasile Pavel,Raluca Maria Hlihor,Elena-Niculina Dragoi,Silvia Curteanu,Markus Lenz,Markus Lenz,Philippe F.-X. Corvini,Maria Gavrilescu +10 more
TL;DR: A methodology based on artificial neural networks and differential evolution (DE), specifically a neuro-evolutionary approach, was applied to model germination rates, dry biomass and root/stem length and proving the robustness of the experimental data.
Journal ArticleDOI
Characterization of heavy metal toxicity in some plants and microorganisms-A preliminary approach for environmental bioremediation.
Mariana Diaconu,Lucian Vasile Pavel,Raluca Maria Hlihor,Mihaela Rosca,Daniela Ionela Fertu,Markus Lenz,P. F. X. Corvini,Maria Gavrilescu +7 more
TL;DR: Investigations on plants and microorganisms revealed their ability to withstand metal toxicity and develop tolerance to heavy metals in soils contaminated with Cr(VI) and Cd(II).
Journal ArticleDOI
Biosorption of copper(II) ions from aqua solutions using dried yeast biomass
TL;DR: In this paper, the ability of yeast Saccharomyces cerevisiae biomass to remove Cu(II) ions from aqueous solutions was investigated by using of batch techniques, and the influence of different parameters on copper uptake by dried yeast, such as initial Cu (II) concentration, initial pH of solution and temperature, was studied.
Journal ArticleDOI
Experimental analysis and mathematical prediction of Cd(II) removal by biosorption using support vector machines and genetic algorithms.
Raluca Maria Hlihor,Mariana Diaconu,Florin Leon,Silvia Curteanu,Teresa Tavares,Maria Gavrilescu +5 more
TL;DR: The complete characterization of bioremoval parameters indicates that T. viride is an excellent material to treat wastewater containing low concentrations of metal and could play an important role in Cd(II) biosorption.
Journal ArticleDOI
Bioremediation of Cr(VI) Polluted Wastewaters by Sorption on Heat Inactivated Saccharomyces cerevisiae Biomass
TL;DR: In this paper, the potential of heat inactivated Saccharomyces cerevisiae in the bioremoval and reduction ofCr (VI) ions from wastewaters was evaluated in terms of metal uptake in time and at equilibrium, and biosorption efficiency, by varying pH, biosorbent doses, contact time and temperature, in batch mode.
