Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
Dunaliella salina is a type of unicellular and halophilic green biflagellate microalga without a rigid cell wall structure. It contains abundant polysaccharide addition to β-carotene. The purpose of present study was to extract of polysaccharide from D. salina with low cost and without organic solvents pollution. In this study, water-soluble polysaccharide was extracted by hydrolyze with alkaline protease. Meanwhile, the contents of heavy metal ion in polysaccharides were reducing at a certain extent. HPLC, IR and GC were performed to detect the molecular weight, structure, monosaccharide composition of the polysaccharide, respectively. The results of hydroxyl radical assay, superoxide anion assay and reducing power assay also indicated that polysaccharide extracted from Dunaliella salina had oxidative stability.
