Abstract

STUDY OF POLYSACHARIDES PRODUCED BY CYANOBACTERIA SPIRULINA PLATENSIS IN MIXTROPHIC CULTIVATION 

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. 

Keywords: Spirulina platensis, cultivation, intracellular polysaccharides, extraction, purification.
