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.

Aquatic ecosystems polluted by heavy metals can affect microalgae growth when their concentrations overcome certain limits, depending on each involved metal species. Yet, for in the low range, exhibit tolerance and accumulate a diversity of species from aqueous media. In particular, Spirulina platensis proved biosorption ability like Zn, Cd, Pb, or Cr, which make it useful bioremediation aquatic media with metals. This prokaryotic cyanobacteria species, has high protein, carbohydrate, fats content, interact through biosorption/bioaccumulation, leading to changes biomass yield, rate, implicitly, composition. paper aims investigate influence some ions development metabolic processes occurring S. platensis, order establish its limitations bioremediation. this regard, submerged cultures involving standardized culture medium (Zarrouk), presence nickel, cadmium, lead different (0.5 mg/L, 1.0 1.5 were considered. The cultivation was carried out 28 days, determination cell mass growth, dry biomass, protein accumulation, viability, pH media, at time intervals (0, 3, 7, 13, 18, 24, days). affected degrees, both type ion concentration. most toxic accumulation nickel cadmium ions, respectively. Cadmium, regardless concentration, caused decrease weight throughout period. Instead, exhibited lowest effect viability integrity spirulina cells, concentration used.

Erbium belongs to rare earth elements critical for industry, especially nuclear technology. Cyanobacteria Arthospira platensis was used Er(III) removal from wastewater by applying biosorption and bioaccumulation processes. The influence of pH, concentration, contact time temperature on the capacity determined. optimal conditions were defined as pH 3.0, 15 min 20 °C, when 30 mg/g removed. kinetics process better described pseudo-first-order model, while equilibrium fitted Freundlich model. In experiments, uptake biomass effect biochemical composition assessed. It shown that in concentrations 10–30 mg/L did not affect content biomass, proteins, carbohydrate photosynthetic pigments. Its toxicity expressed reduction lipids growth level malonic dialdehyde. Biomass accumulated 45–78% Eu(III) present cultivation medium. Therefore, can be considered a safe efficient bioremediator erbium contaminated environment.

Europium recovery from wastewater is determined by its high significance for industry and toxicity living organisms. The capacity of cyanobacteria Arthospira platensis (Spirulina) to remove Eu(III) through biosorption bioaccumulation was evaluated. In experiments, the effects four variables pH, metal concentration, time, temperature on removal were studied. effect concentrations biomass biochemical composition assessed. efficiency uptake in both experiments using ICP-AES techniques. Maximum achieved at pH 3.0. Equilibrium data fitted well with Langmuir Freundlich models, maximum adsorption 89.5 mg/g. pseudo-first-, pseudo-second-order, Elovich models found correlate experimental data. According thermodynamic studies sorption feasible, spontaneous, endothermic nature. At addition ions cultivation medium 10–30 mg/L, accumulation 9.8–29.8 mg/g (removal constituting 98–99%). did not affect productivity content carbohydrates pigments but led decrease protein an increase amount MDA.
