AbstractZinc is an important metal for humans and the environment. Its intensive application in industry has led to water and soilcontamination. A lot of microorganisms both unicellular and multicellular can be applied for removal of metals from theenvironment. The process of zinc adsorption by cyanobacteria Spirulina platensis biomass was investigated. The concentrationsof 0.34 mM and 3.4 mM of ZnSO4ˇ7H2O were used. The process of biosorption of zinc was studied during 1-hour experiment.To dete...

Growth rate and biomass yield in the case of Arthrospira platensis depend on nutrient availability, temperature and light, which can determine changes in the metabolism and therefore in the biomass composition. The aim of this study is to evaluate the behavior of A. platensis during the growing time in several liquid culture media and their influence on the yield of biomass production. The following culture media have been investigated in this sense: ARS, Zarrouk (Z), modified Zarrouk (MZ), eco...
