“…Increasing environmental awareness and concern has attracted scientific community to extend its exploitation more vigorously in the area of phytoremediation because the fern can hyperaccumulate variety of pollutants such as heavy metals, radionuclides, dyes, and pesticides etc. from aquatic ecosystems along with other macrophytes (Padmesh et al 2006;Rai and Tripathi 2009;Mashkani and Ghazvini 2009;Sood et al 2011). This fern has many features that prove it as a better plant system than many other macrophytes, which include:…”

Aquatic macrophytes play an important role in the structural and functional aspects of aquatic ecosystems by altering water movement regimes, providing shelter to fish and aquatic invertebrates, serving as a food source, and altering water quality by regulating oxygen balance, nutrient cycles, and accumulating heavy metals. The ability to hyperaccumulate heavy metals makes them interesting research candidates, especially for the treatment of industrial effluents and sewage waste water. The use of aquatic macrophytes, such as Azolla with hyper accumulating ability is known to be an environmentally friendly option to restore polluted aquatic resources. The present review highlights the phytoaccumulation potential of macrophytes with emphasis on utilization of Azolla as a promising candidate for phytoremediation. The impact of uptake of heavy metals on morphology and metabolic processes of Azolla has also been discussed for a better understanding and utilization of this symbiotic association in the field of phytoremediation.

This fern has many features that prove it as a better plant system than many other macrophytes, which include: Fast Growth Rate: The ability of Azolla to grow rapidly, doubling its biomass in 2-4 days, is the most important attribute, along with its free-floating nature (Arora and Saxena 2005;Kathiresan 2007;Sood et al, 2008a).…”

“…Many biosorbents have been used to remove dyes from aqueous solutions, such as, Chlorella vulgaris (Aksu and Tezer, 2005), Azolla rongpong (Padmesh et al, 2006), Aspergillus foetidus (Patel and Suresh, 2008), Aspergillus parasiticus (Akar et al, 2009), Ulothrix sp. (Dogar et al, 2010) and Nostoc linckia (Mona et al, 2011), but studies about the use of S. platensis are very limited.…”

-The equilibrium and thermodynamics of azo dye (tartrazine and allura red) biosorption onto Spirulina platensis biomass were investigated. The equilibrium curves were obtained at 298, 308, 318 and 328 K, and four isotherm models were fitted the experimental data. Biosorption thermodynamic parameters (ΔG, ΔH and ΔS) were estimated. The results showed that the biosorption was favored by a temperature decrease. For both dyes, the Sips model was the best to represent the equilibrium experimental data (R 2 >0.99 and ARE<5.0%) and the maximum biosorption capacities were 363.2 and 468.7 mg g -1 for tartrazine and allura red, respectively, obtained at 298 K. The negative values of ΔG and ΔH showed that the biosorption of both dyes was spontaneous, favorable and exothermic. The positive values of ΔS suggested that the system disorder increases during the biosorption process.
