Characteristics and potential of micro algal cultivation strategies: a review (2012, background): “The removal of Ni(II), Fe(II/III), Hg(II), Cd(II), Cr(IV), Zn(II) or Au(II) ions fromwaste water by different immobilized Chlorella and Scenedesmus strains was also investigated and reported in literature (Becher, 1983; Brierley et al., 1986; Mallick, 2002; Mehta and Gaur, 2005).”
Metal bioremediation by CrMTP4 over-expressing Chlamydomonas reinhardtii in comparison to natural wastewater-tolerant microalgae strains (2017, background): “The potential of using plants and algae for metal bioremediation has led to 58 widespread evaluation of natural species that have innate or adapted ability for metal 59 tolerance and accumulation [1-3].”
The dual roles of phycoremediation of wet market wastewater for nutrients and heavy metals removal and microalgae biomass production (2016, background): “Besides, microalgae have high potential to resist heavy metals, therefore, it has been used to remove heavy metals from different types of wastewater (Cavet et al. 2003; Mehta and Gaura 2005).”
Biological Removal and Recovery of Toxic Heavy Metals in Water Environment (2012, methodology): “…of target metals, competing ions, and suspended solids of the influent, flow rate, size of biosorbent particles, and column length are important operational parameters in controlling metal removal efficiencies of the packed-bed column reactors (Kratochvil and Volesky, 1998; Mehta and Gaur, 2005).”
Biomass-derived biosorbents for metal ions sequestration: Adsorbent modification and activation methods and adsorbent regeneration (2014, background): “Even though HCl has a very high capacity to desorb metals, several studies have shown that it would also decrease metal adsorption abilities of the regenerated biosorbents because of hydrolysis of the polysaccharides on the biomass surface as metal binding sites [233,234].”
Bioactive compounds in seaweed: functional food applications and legislation (2011, background): “and wastewater or in the use of seaweed as a bioindicator (Boubonari et al. 2008; Cruz-Uribe et al. 2007; Mehta and Gaur 2005).”
Biorecovery of gold using cyanobacteria and an eukaryotic alga with special reference to nanogold formation – a novel phenomenon (2009, background): “1) can be attributed to their differences in chemical composition of cell surface leading also to variable chemical interactions (Mehta and Gaur 2005).”
Microalgal Biostimulants and Biofertilisers in Crop Productions (2019, background): “Mehta and Gaur [103] reported that complexation and microprecipitation are the most important mechanisms to avoid heavy metal toxicity used by microalgae.”
Microalgae - A promising tool for heavy metal remediation. (2015, background): “In case of bioremediation of HMs by algae, the presence of high concentrations of monovalent cations (Naþ and Kþ) causes an increase in ionic strength of a wastewater; this, in turn, decreases metal biosorption capacity of the biomass (Mehta and Gaur, 2005).”
Screening of different algae for green synthesis of gold nanoparticles (2012, background): “Over the past few decades many attempts have been made to understand the roles that organisms can play in the accumulation of gold and its conversion to non‐toxic nanoparticles (Mehta & Gaur, 2005 ).”
Sustainability and cyanobacteria (blue-green algae): facts and challenges (2011, methodology): “Each functional group has a specific dissociation constant and dissociates into corresponding anion and proton at a specific pH (Mehta and Gaur 2005 and references therein).”
