“…Another issue, which is often neglected in the literature, is the investigation of the effects of anions on biosorption processes. This aspect should also be taken into consideration because the presence of anions in aqueous solutions could affect metal cation biosorption [8].In the literature, two aspects of the effects of anions on biosorption processes are considered: the effects of anions on the maximum biosorption capacity in single-metal systems [9], and the effects of anion concentration on the biosorption of several metal ions in multi-metal systems [8,10,11]. It is important to emphasize that the influence of the anion on the biosorption capacity could differ depending on the biomass used and the biosorbed metal ions.…”

The results of research on the effects of anions on the biosorption of microelement cations by the edible marine macroalga Enteromorpha prolifera in single-and multi-metal systems are discussed in this paper. It was shown that the maximum biosorption capacity (q max ) in a single-metal system of Co (II) The biosorption of metal ions by algae has been widely reported in the literature. However, the majority of the published work describes single-metal biosorption systems. Very little information is available on multi-metal biosorption systems such as binary [1][2][3][4][5], ternary [1,[4][5][6], and quaternary systems [7]. There is a necessity to perform experiments on such systems because they better reflect real effluents from industrial operations. Another issue, which is often neglected in the literature, is the investigation of the effects of anions on biosorption processes. This aspect should also be taken into consideration because the presence of anions in aqueous solutions could affect metal cation biosorption [8].In the literature, two aspects of the effects of anions on biosorption processes are considered: the effects of anions on the maximum biosorption capacity in single-metal systems [9], and the effects of anion concentration on the biosorption of several metal ions in multi-metal systems [8,10,11]. It is important to emphasize that the influence of the anion on the biosorption capacity could differ depending on the biomass used and the biosorbed metal ions. The anions NO 3 -and SO 4 2-did not significantly influence the removal efficiency of the fungus Aspergillus niger for Cr(VI), Co(II), Ni(II), and Zn(II) ions, whereas the presence of Cl -anions significantly decreased the efficiency of metal ion biosorption in multi-metal systems [10]. In the case of another fungus, namely Rhizopus arrhizus, the degree of inhibition of the biosorption of La(III), Cd(II), Pb(II), and Ag(I) cations generally followed the order EDTA > SO 4 2-> Cl -> PO 4 3-> glutamate > CO 3 2- [12]. During biosorption of Co(II) cations by the brown macroalga Ascophylum nodosum, the presence of SO 4 2-and PO 4 3-anions did not result in any change in biosorption, in contrast to NO 3 -anions, which were the strongest inhibitor [13]. The opposite situation was observed in the case of biosorption of Zn(II) cations by the cyanobacterium Oscillatoria anguistissim, for which the inhibitory order of the anions was as follows: SO 4 2-> Cl -> NO 3 -(i.e., SO 4 2-anions were the strongest inhibitor) [11].

“…High zinc adsorption was reported for an other O. angustissima strain and for Microcystis sp. (641.25 and 999.5 mg g -1 , respectively; Ahuja et al 1999;Pradhan et al 1998). Otherwise, the application of these cyanobacteria as biosorbents is questionable, because of their possible toxic properties (Vasas et al 2010(Vasas et al , 2013.…”

Effects of zinc on growth, cell morphology, oxidative stress responses and zinc removal activity of two common phytoplankton species, Monoraphidium pusillum (Printz) Komárková-Legnerová and Monoraphidium griffithii (Berkeley) Komárková-Legnerová were investigated at a concentration range of 0.2-160 mg l -1 zinc. Cell densities and chlorophyll content decreased compared with controls in cultures of both species, effective concentrations causing 50 % growth inhibition within 72 h on the basis of cell numbers were 33.69 and 25.63 mg l -1 zinc for M. pusillum and M. griffithii, respectively. Changes in cell morphology and elevated lipid peroxidation levels appeared in zinc-treated cultures of both species, but only at higher ([10 mg l -1 ) zinc concentrations. The most effective zinc removal appeared at 20 and 10 mg l -1 zinc concentration for M. pusillum and M. griffithii, respectively. Removed zinc is mainly bound on the cell surface in the case of both species. This study provides new data for the zinc tolerance and zinc removal ability of the green algae M. pusillum and M. griffithii and shows that green algal species common in surface waters could have zinc tolerance and zinc-binding abilities, which makes them feasible in treatment of waters contaminated with 10-20 mg l -1 zinc.

“…In a study by Rabsch and Elbracher (1980), they observed that heat-killed cells of Coscinodiscus granii could accumulate three times more zinc than its live cells. The uptake of zinc metal by microalgal consortia is comparatively higher (Ahuja et al 1999). Some studies showed that in immobilized monocultures or consortia on alginate have greater metal uptake potential (Brun et al 1998;Gloaguen et al 1996;Ye et al 1997).…”

A set of experiments was conducted to provide significant insights of micro-algal consortia regarding chromium adsorption. Four monocultures; Scenedesmus dimorphus, Chlorella sp., Oscillatoria sp., and Lyngbya sp., and their synthetic consortia were evaluated initially for chromium bio-adsorption at four different regimes of hexavalent chromium i.e. 0.5, 1.0, 3.0 and 5.0 ppm. Based on findings, only 1.0 and 5.0 ppm were considered for future experiments. Consequently, three different types of monoculture and consortia cells namely; live cells, heatkilled cells, and pre-treated cells were prepared to enhance their adsorption potential. Maximal adsorption of 112% was obtained at the dose of 1.0 ppm with 0.1% SDS pretreated consortia cells over live consortia cells. In support, atomic absorption spectroscopy, laser induced breakdown spectroscopy, pulse amplitude modulated chlorophyll fluorescence, and scanning electron microscopy were performed to assess the structural and functional changes within consortia and their utilization in mitigation of elevated chromium levels.Keywords Micro-algal consortia Á Pulse amplitude modulated chlorophyll fluorescence (PAM) Á Scanning electron microscopy (SEM) Á Laser induced breakdown spectroscopy (LIBS) Á Atomic absorption spectroscopy (AAS)
