“…The pellet and organic layer were retained. The lyophilization of bacterial samples was performed using the published procedure [24]. The deglycosylation with TFMS has the advantage over enzymatic removal of sugars in that all carbohydrate groups tested to date can be removed in a single step, while leaving the protein backbone intact [25].…”

“…In the literature, there are information on biotransformations in which not efficient inorganic forms of microelements are transformed into organic forms by binding with proteins, lipids and polysaccharides and other cell components, which are more bioavailable [11] . One of many examples of modified organisms is Spirulina sp., which was transformed into Se-supplementable alga in biacumulation process [36,37] . Biomass of Spirulina sp.…”

Equilibrium experiments of chromium(III) biosorption by m icroalga (Spirulina sp.) and macroalga (Pithophora varia) were investigated in this paper. Influence of the following process parameters was studied: pH, biomass concentration and temperature. The equilibrium of the process was described with Langmuir equation. The model parameters were determined at various process conditions. The best operation conditions for the process were selected: pH 5, T 20 o C, C s 1g.l -1 for Pithophora varia and the same for Spirulina sp. Under these conditions, the maximum biosorption capacity 60.6 mg.g -1 and 34.6 mg.g -1 , and affinity constant 0.182 l.mg -1 and 0.0553 l.mg -1 were reached for Pithophora varia and Spirulina sp., respectively. It was found that Pithophora varia was more efficient in biosorption of Cr(III) ions than Spirulina sp. Biosorptive properties of microalgal and macroalgal biomass can be employed either in the production of biological feed supplements for livestock or in wastewater treatment processes.

“…Timiriazev Institute for Plant Physiology of the Russian Academy of Sciences was used. The cultivation conditions for S. platensis cells in standard water-salt nutrient medium are described elsewhere [13,14]. After 5-day cultivation, cells of S. platensis were separated from the culture broth by centrifugation (12,000 g) for 20 min, and then the biomass was washed twice with sterile distilled water.…”

“…In our earlier investigations, S. platensis was used as a matrix for the development of new pharmaceutical substances [13][14][15][16]. The elemental content of the initial biomass of Spirulina was studied using the neutron activation analysis; it was shown that the concentrations of some toxic elements in the biomass of S. platensis do not exceed permissible levels [14].…”

Abstract:The synthesis of gold and silver nanoparticles by the blue-green algae Spirulina platensis for medical purposes was studied. A complex of optical and analytical methods was used in order to characterize produced nanoparticles. It was shown that the extracellular formation of metal nanoparticles of spherical shape with sizes in the range between 8 and 40 nm (the average size of 20-30 nm) takes place. The characteristics of gold and silver nanoparticles in the Spirulina biomass were compared. The role of biosorption processes in the synthesis of nanoparticles was estimated by using equilibrium dialysis. A positive influence of sonication on the process of microbial synthesis and yield of nanoparticles were demonstrated. The neutron activation analysis and the atomic absorption spectrometry were applied for characterizing the dynamics of gold and silver nanoparticles formation in the Spirulina platensis biomass. The neutron activation analysis was used for studying the elemental content of the Spirulina platensis biomass.
