In prezentul studiu a fost evaluat efectul acetaţilor de Cu(II) şi Zn(II) cu şi fără adaos de glucoză şi al iluminării asupra productivităţii şi producerii polizaharidelor intracelulare la cianobacteria Spirulina platensis. A fost analizată componenţa fracţiilor polizaharid
ice obţinute la separare prin cromatografia pe coloana de Toyo-Pearl şi stabilită natura
lor proteoglicanică. A fost propusă schema de realizare a unui procedeu de extragere şi purificare a complexului de polizaharide din biomasă.
In the present work, the authors studied the effect of Cu (II) and Zn (II) acetates with and without addition of glucose and the influence of two illumination regimes on the productivity and production of intracellular polysaccharides in cyanobacterium
Spirulina platensis. The composition of the polysaccharide fractions obtained by chromatographic
separation on a Toyo-Pearl column was analyzed and their proteoglycanic nature was determined. A scheme for the
extraction and purification procedure of the polysaccharide complex from biomass has been proposed.
