“…Moreover, the q max values obtained in the present study exceeded those in earlier reports [12,23,29,34]. In the earlier researches, q max was 98.04 mg/ml in the blue-green microalgae Scenedesmus platensis [28], 85.30 mg/g in the green microalgae Chlorella vulgaris [34], 88.20 mg/g in the filamentous green microalgae Oedogonium sp. [14] and 27.3 mg/g in the macro fungus Amanita rubescens [25].…”

Abstract. Dried biosorbent was prepared from Aphanothece sp. cyanobacteria harvested from a photobioreactor system fed with atmospheric carbon dioxide. Cadmium-ion biosorption of the prepared biosorbent from aqueous solution was characterized by non-linear (Langmuir, Freundlich and Dubinin-Radushkevich) isotherms, non-linear kinetics (pseudo first-order and pseudo second-order) and thermodynamic analysis. The optimum conditions were pH 8.0, 30°C, 0.1 g/L biomass, and 60 min contact time. The biosorption efficiencies exceeded 90%. The low-range data (initial Cd concentration C 0 = 1.09-6.23 mg/L) and highrange data (C 0 = 5.41-83.07 mg/L) were best fitted to the Langmuir model, with maximum uptake capacities of 12.01 and 187.5 mg/g (R 2 = 0.995 and 0.996). In the Dubinin-Radushkevich isotherm model, the mean biosorption energy was 12.91 kJ/mol, suggesting that ion exchange was the working mechanism. The biosorption apparently followed pseudo second-order kinetics (R 2 = 0.994-0.999; k 2 = 2.04 E-03 to 3.86 E-02 g/mg min). The biosorption process was energetically feasible (∆G 0 = −13.47-−8.88 kJ/mol), exothermic (∆H 0 = −74.82 kJ/mol) and tended to become more ordered (∆S 0 = −0.204 kJ/mol K) towards the end of the process. The biosorbent was reusable through three adsorption/desorption cycles in 1 M HCl.

“…Even so coccoid algae, which were very small after being so thinned, were easily isolated from lake waters. After obtaining single cells (Filaments of Cyanobacteria cells or cell colonies of Chlorophyta), they were transferred to BG-11 medium (NaNO3, 15; K2HPO4, 0.4; MgSO4·7H2O, 0.75; CaCl2·2H2O, 0.36; citric acid, 0.06; iron (III) ammonium citrate, 0.06; Na2-EDTA, 0.01; Na2CO3, 0.2 g/L, 1 mL; trace elements solution, (H3BO3, 61; MnSO4·H2O, 169; ZnSO4·7H2O, 287; CuSO4·5H2O, 2.5; (NH4)6Mo7O24·4H2O, 12.5 mg/L) in accordance with the procedure stated in Rippka (1988) (Katırcıoğlu, Aslım, Türker, Atıcı & Beyatlı, 2008;Rippka, 1988). This medium which has been frequently used for the growth of Cyanobacteria and Chlorophyta.…”

Morphological features are not sufficient for species characterization in microalgae. There are many possibilities for existing characters. Recently, molecular techniques have been used in many areas and this technique increasing the reliability of the work done. The general purpose of the study is to compare Cyanobacteria and Chlorophyta species under the culture conditions using classical classification and molecular identification. In order to achieve this aim, isolation of different clonal cultures of Cyanobacteria and Chlorophyta species from Apa

“…The major advantages of biosorption techniques are that they are low cost, simple and time saving. For preconcentration and removal of trace metals, yeast, bacteria, algae and fungus have been used, either free or immobilized, and/or either live or dead [14]. Immobilized biomass systems could provide additional advantages over freely suspended cells.…”

“…These advantages include ease of regeneration and reuse of the biomass, easier solid-liquid separation and suitability to on-line flow techniques. Natural and synthetic materials such as alginate [14], chitosan [15], Amberlite XAD resins [2] and silica gel [4] have been the most used support materials for the immobilization of microbial cells.…”

This study presents a procedure for preconcentration of Cr(III), Cd(II) and Mn(II) from water and biological samples using Penicillium digitatum immobilized on pumice stone. Optimum conditions such as pH, flow rate were evaluated. The recoveries of Cr(III), Cd(II) and Mn(II) under optimum conditions were found to be 98 l 2%, 100 l 2%, and 97 l 2%, respectively, at a 95% confidence level. Detection limits were 2.0, 1.6 and 1.5 ng/mL for Cr(III), Cd(II) and Mn(II), respectively. The proposed procedure was successfully applied for the determination of chromium, cadmium and manganese in dam water, spring water and fish (Carp) samples. The accuracy was evaluated through the analysis of the certified standard reference fish tissue samples (IAEA-407) and spiked fish and water samples.
