The use of living Arthrospira platensis (A. platensis) cultures emerges as a promising green solution for the bioremediation water contaminated by toxic metal waste. scope present study is to evaluate microalga’s potential in heavy remediation, case multi-metal-treated (multi-MT) systems. For this reason, A. were exposed mono- and multi-metal solutions Cu, Cd, Ni, Pb, Zn, their adsorption ability was investigated. removal efficiency evaluated using atomic absorption spectroscopy (AAS). Additionally, examined Fourier transform infrared (FTIR) spectroscopy, Near-Infrared (NIR) Spectroscopy, UV-Vis spectrophotometry, optical microscopy, together with pH electrical conductivity (EC) measurements quality changes induced stress. results showed that still efficient multi-MT cultures. In particular, Zn elevated or relative respective mono-metal-treated (mono-MT) cultures, showing synergistic cooperative interaction between metals, while Ni decreased compared mono-MT an antagonistic other metals. shows considered effective microalga toward polluted

In recent years, overexplorations of ore and the growth industries are prime factors in release heavy metals environments. As a result, food crops water bodies contaminated with which may have several adverse effects on health humans other living species. These metalloids, such as Zn, Cu, Mn, Ni, Cr, Pb, Cd, As, upset biochemical pathways metabolite synthesis organisms contribute to etiology different diseases. Microorganisms include bacteria, archaea, viruses, many unicellular eukaryotes, can span three domains life—Archaea, Bacteria, Eukarya—and some microorganisms, cyanobacteria, shown high efficiency biosorption rate metals. Cyanobacteria suitable for bioremediation they grow environments, less negative impact surrounding environment, relatively cheaper manage. The structure cyanobacteria has no extensive internal-bound membranes, so it directly employ physiological mechanisms uptake from contamination sites. Such makeups managing bioremediating metal concentrations polluted This review aims explore potential metalloids bodies. Additionally, we identified prospects enhancing effectiveness.
