“…Similarly, Petruzzi et al, (2016) assessed the stability of Saccharomyces cerevisiae W13ochratoxin A complex under simulated GIT conditions and stated that approximately 70% of the toxin was released after 6 h exposure to salivary and simulated GIT juices (Petruzzi, Corbo et al, 2016). In addition, Mirmahdi et al, (2022) reported that bonds of heavy metal-Saccharomyces cerevisiae complexes in digestion conditions were reversible.…”

“…Therefore, it is necessary to investigate regarding simultaneous removal of heavy metals in multi-metallic contaminated drinking water. In this research teams' previous work, we used Saccharomyces cerevisiae ATCC 9763 for biosorption of heavy metals (As, Pb, Hg, and Cd) from drinking water (Mirmahdi, Mofid et al, 2022). In this study, L. acidophilus ATCC 4356 was used to remove these metals due to the ability of this bacterium in biosorption of heavy metals.…”

Water contamination with heavy metals is increased due to environmental contaminants. Arsenic, cadmium, mer-cury, and lead are well-known toxic heavy metals for humans. Lactobacillus acidophilus is an ideal absorbent for the removal of metals from drinking water. In this study, the ability of treated and untreated L. acidophilus ATCC 4356 to remove four heavy metals, simultaneously, from multi-metallic contaminated water in 24 h was investigated. In addition, the stability of the bacteria–metal complexes was evaluated in simulated gastrointestinal tract conditions. According to the results, untreated L. acidophilus could remove 99.01% and 92.35% of mercury and lead in water, respectively (initial concentration of 700 µg.L−1; inoculum size of 2.6×1012 CFU.mL−1; pH 4; 37°C; 24 h), whereas removal of arsenic and cadmium, under the same conditions, was 91.28% and 61.91% by heat and NaOH treated cells, respectively. In the digest condition, the complexes of bacteria-metal were reversible and the bond stability of untreated bacteria–Hg complexes was stronger than other complexes. The results suggest that treated or untreated L. acidophilus ATCC 4356 cells have the potential to adsorb heavy metals in contaminated water.

“…Heavy metals such as arsenic, cadmium, lead, and mercury are some of these pollutants, and elimination of them from the body is on the research agenda ( Ahmed et al., 2017 ; Feng et al., 2022 ). Several studies have proven that probiotic bacteria have the ability to absorb heavy metals and remove pollution caused by them ( Massoud and Zoghi, 2022 ; Mirmahdi et al., 2022 ). The Lactobacillus bacteria can absorb and remove some extent of these heavy metals ( Singh et al., 2022 ; Majlesi et al., 2017 ).…”

“…Two isotherm models (Langmuir and Freundlich), three kinetics models (pseudo-firstorder (1st), pseudo-second-order (2nd), and intraparticle diffusion), and thermodynamic parameters were utilized to model the empirical data using the mathematical formulas [29,34,47] prescribed in Table 1. The best isotherm and kinetics models were selected relying on the regression coefficients (R 2 ), estimated statistically.…”

“…Thus, efficient and low-cost processes for producing large-scale yeast biomass have evolved. S. cerevisiae is a promising biosorbent that has been shown to eliminate pesticides [31], mycotoxins [32], and trace elements from synthesized water or aqueous solutions, even when deactivated, and it has its highest efficiency in short contact times [7,29,[33][34][35][36][37][38][39][40][41][42][43][44][45]. Furthermore, the encapsulation of S. cerevisiae in a biopolymer, for example, alginate [32,43,[46][47][48][49][50], is an alternative strategy for their application, as well as being steadier, simple-to-deal with, and economical.…”

The examination of the performance of raw and immobilized S. (Saccharomyces) cerevisiae in the simultaneous abatement of metal ions from wastewater effluent is the focal point of this article. The optimal storage time for raw and immobilized S. cerevisiae, during which they can be utilized, was estimated. The outcomes revealed that as the initial metal ion concentrations increased, the adsorption capacity improved, while the removal efficiency of S. cerevisiae yeast cells decreased, with the highest uptake obtained at the optimal conditions: pH = 5.0, 2.0 g S. cerevisiae/L, 25 °C, and a contact time of 25 min. The maximum adsorption capacities (qmax) for Pb(II), Cd(II), and Ni(II) ions are shown by Langmuir at 65, 90, and 51 mg/g, respectively. It was discovered that the metal ions’ biosorption reactions were spontaneous and were fitted by the pseudo-second-order model. The mechanisms of the metal ions’ abatement were explained by using XRD (X-ray diffraction), FTIR (Fourier transform infrared spectroscopy), (BET) Brunauer–Emmett–Teller, and TEM (transmission electron microscopy) outputs. EDTA and citric acid can eliminate more than 70 ± 4 and 90 ± 5% of the adsorbed ions, respectively. The experiment of storage demonstrated that the immobilized S. cerevisiae was more stable for 8 months than the raw yeast.
