“…With the pH increase, the cell surface becomes more negatively charged, resulting in the increase of the affinity to metal ions in cationic form. At pH 6.0, Candida rugosa biofilm showed maximum Zn(II) removal of 44%, whereas Cryptococcus laurentii biofilm removed 37% of Zn(II) [ 3 ]. Cu 2+ and Zn 2+ were effectively removed from aqueous solutions by S. cerevisiae crosslinked with formaldehyde at pH 5.3 and 6.0, respectively [ 8 ].…”

“…Zinc is an essential element involved in different metabolic processes and an important component of more than 200 enzymes [ 2 ]. At the same time, zinc compounds are widely used in different industrial processes, which often result in the release of zinc ions into the environment, at a concentration of physiological and ecological concern [ 3 ]. Wastewater released by different industrial processes (electroplating and surface finishing) and mining contain high concentrations of zinc among other metal ions [ 4 ].…”

“…S. cerevisiae is extensively used in beverage and food production and is obtained in large quantities, as a by-product of the fermentation industry [ 5 ]. It was already shown that S. cerevisiae can remove toxic metals and radionuclides from aqueous solutions [ 1 , 3 , 4 , 5 , 6 , 7 ]. In the Ozer and Ozer [ 7 ] study, inactive S. cerevisiae biomass showed the highest sorption capacity for Pb(II) ions, followed by Ni(II) and Cr(VI).…”

The performance of the brewer’s yeast Saccharomyces cerevisiae to remove metal ions from four batch systems, namely Zn(II), Zn(II)-Sr(II)-Cu(II), Zn(II)-Ni(II)-Cu(II), and Zn(II)-Sr(II)-Cu(II)-Ba(II), and one real effluent was evaluated. Yeast biosorption capacity under different pH, temperature, initial zinc concentration, and contact time was investigated. The optimal pH for removal of metal ions present in the analyzed solution (Zn, Cu, Ni, Sr, and Ba) varied from 3.0 to 6.0. The biosorption process for zinc ions in all systems obeys Langmuir adsorption isotherm, and, in some cases, the Freundlich model was applicable as well. The kinetics of metal ions biosorption was described by pseudo-first-order, pseudo-second-order, and Elovich models. Thermodynamic calculations showed that metal biosorption was a spontaneous process. The two-stage sequential scheme of zinc ions removal from real effluent by the addition of different dosages of new sorbent allowed us to achieve a high efficiency of Zn(II) ions removal from the effluent. FTIR revealed that OH, C=C, C=O, C–H, C–N, and NH groups were the main biosorption sites for metal ions.

“…Etracellular polysaccharides (EPS) play a significant role in cell adhesion and biofilm formation, which is closely related to colonization, mineral solubilizing ability, and protection against adverse environmental conditions (Basak et al, 2014;Marino et al, 2018;Yu et al, 2019). Gene clusters encoding for d-TDP-glucose pyrophosphorylase (rfbA), d-TDP-glucose 4,6dehydratase (rfbB), d-TDP-4-dehydrorhamnose 3,5-epimerase (rfbC), and d-TDP-4-dehydrorhamnose reductase (rfbD), which can convert glucose-1-phosphate to the EPS precursor d-TDP-rhamnose via a series of reactions, were found in all Metallosphaera genomes (Supplementary Figure S9).…”

Members of the genus Metallosphaera are widely found in sulfur-rich and metal-laden environments, but their physiological and ecological roles remain poorly understood. Here, we sequenced Metallosphaera tengchongensis Ric-A, a strain isolated from the Tengchong hot spring in Yunnan Province, China, and performed a comparative genome analysis with other Metallosphaera genomes. The genome of M. tengchongensis had an average nucleotide identity (ANI) of approximately 70% to that of Metallosphaera cuprina. Genes sqr, tth, sir, tqo, hdr, tst, soe, and sdo associated with sulfur oxidation, and gene clusters fox and cbs involved in iron oxidation existed in all Metallosphaera genomes. However, the adenosine-5-phosphosulfate (APS) pathway was only detected in Metallosphaera sedula and Metallosphaera yellowstonensis, and several subunits of fox cluster were lost in M. cuprina. The complete 3hydroxypropionate/4-hydroxybutyrate cycle and dicarboxylate/4-hydroxybutyrate cycle involved in carbon fixation were found in all Metallosphaera genomes. A large number of gene family gain events occurred in M. yellowstonensis and M. sedula, whereas gene family loss events occurred frequently in M. cuprina. Pervasive strong purifying selection was found acting on the gene families of Metallosphaera, of which transcriptionrelated genes underwent the strongest purifying selection. In contrast, genes related to prophages, transposons, and defense mechanisms were under weaker purifying pressure. Taken together, this study expands knowledge of the genomic traits of Metallosphaera species and sheds light on their evolution.

“…These results are in agreement with those obtained by Padmavathy et al [21], who suggested that mannoproteins and glucans present on the cell wall were responsible for the sorption of Ni(II) ions. According to Basak et al [22] carboxyl, phosphate, sulfhydryl, hydroxyl and nitrogen-containing groups of yeast biomass surface participated in the removal of Zn(II) ion. Gerlach et al [27] have found that OH groups play the main role in iron ions binding.…”

Saccharomyces cerevisiae, waste biomass originated from beer fermentation industry, was used to remove metal ions from four copper-containing synthetic effluents: Cu-Fe, Cu-Fe-Ni, Cu-Fe-Zn, and Cu-Fe-Ni-Zn. The characterization of the biomass surface was investigated by Scanning Electron Microscopy and Fourier-transform Infrared Spectroscopy. The adsorption behavior of Saccharomyces cerevisiae for copper, iron, nickel and zinc ions in aqueous solution was studied as a function of pH, initial copper concentration, equilibrium time, and temperature. Langmiur, Freundlich, Temkin and Dubinin-Radushkevich equilibrium models have been assessed to describe the experimental sorption equilibrium profile, while pseudo-first order, pseudo-second order, Elovich and the intra-particle diffusion models were applied to describe experimental kinetics data. Maximum sorption capacities have been calculated by means of Langmuir equilibrium model and mean free sorption energies through the Dubinin-Radushkevich model. Thermodynamic analysis results showed that the adsorption of copper, iron and zinc was spontaneous and endothermic in nature, while of nickel exothermic. Saccharomyces cerevisiae can be successfully applied for complex wastewater treatment.
