Optimization of As (III) and As (V) removal by Saccharomyces cerevisiae biomass for biosorption of critical levels in the food and water resources

Risk of low stability Saccharomyces cerevisiae ATCC 9763-heavy metals complex in gastrointestinal simulated conditions

“…Results have verified the ability of S. cerevisiae in biosorption of all metals and heavy metals, even As. The bioremoval ability of yeast depends on various factors such as initial yeast biomass, initial heavy metal concentration, pH, ambient temperature, presence of other heavy metal ions, contact time, and composition of culture media ( Hadiani et al., 2018a , Hadiani et al., 2018b ; Hadiani et al., 2019 ). Naturally, S. cerevisiae includes phosphodiester bridges on its cell that produce negative surface charges.…”

Insight on water remediation application using magnetic nanomaterials and biosorbents

“…Photooxidation [302], phytoextraction [303], electrocoagulation [304], electrodialysis [305] (Nemati et al, 2017), irradiation [306], membrane separation [307], ultrafiltration [308], forward osmosis [309], ion exchange [310], precipitation [311], coagulation/flocculation [312,313], microorganisms and plants [314][315][316] are applied to tackle different water pollutants from aquatic systems. However, most of these sophisticated processes have many certain limitations and restrictions such as high costs, inefficiency in low pollutants concentrations, long cycle times, reagents and energy consumption and chemical sewage sludge formation [317,318].…”

Perspectives regarding metal/mineral-incorporating materials for water purification: with special focus on Cr(vi) removal

“…Yet, the majority of these complicated processes could introduce some challenges, e.g., high costs, inefficiency in low-concentration polluters, huge time consumption, reagents and energy, and formation of chemical sewage sludge. 48,49 Based on the famous comment of Albert Einstein, ''We can't solve our problems by using the same kind of thinking we used when we created them. '', it is time to come up with alternative, greener, and cheaper technology for eliminating contaminants from water efficiently.…”
