Abstract
Enzymatic and nonenzymatic antioxidant potentials of Chlorella vulgaris have gained considerable importance in recent decades C vulgaris strain highly tolerant to extreme pH variations was isolated and masscultivated in the wastewater from a confectionery industry Cvulgaris showed better growth in wastewater than in improvised CFTRI medium The microalgal biomass was then screened for the following antioxidants peroxidase superoxide dismutase polyphenol oxidase glutathione peroxidase chlorophyll a ascorbic acid αtocopherol and reduced glutathione The total polyphenol content of the strain was also studied The strain showed a high degree of enzymatic antioxidant activity 0195 × 10−5 ± 00072 units/cell peroxidase 004125 × 10−5 ± 0001 units/cell superoxide dismutase 02625 × 10−5 ± 0003 units/cell polyphenol oxidase and 0025 × 10−5 ± 0003 glutathione peroxidase The microalgal biomass also showed per milligram weight 02182 ± 0005 μg of ascorbic acid 000264 ± 0001 μg of αtocopherol and 007916 ± 0004 μg of reduced glutathione These results represent the possibility of using C vulgaris grown in confectionery industry wastewater as a source of nutritious supplement which is highly promising in terms of both economic and nutritional point of view
