| dc.description.abstract | Phycocyanin is a blue pigment-protein complex synthesized by microalgae
Spirulina platensis. It has been used in the food and biotechnology because of
their color, fluorescence and antioxidant properties. In Vietnam, the highest
content of phycocyanin extracted was lower than 5%. The object of this study
was to obtain the highest yield of phycocyanin under different treatments
(solvents, ultrasonic temperature and enzyme treatment conditions including
concentration, pH and temperature). Method used in this study for phycocyanin
quantification was spectrophotometer at wavelengths 652nm and 515nm. As a
result, it released the highest yield at 92.31mg/g of dry biomass, achieved
around 8.6% of extraction under ultrasonic temperature of 40℃ for 10 minutes
combined enzyme treatment with enzyme concentration of 2% at pH 5 and
temperature at 50℃ for 1 hour. Contribution of this study for science is to
provide a reference using ultrasound and Viscozyme L on the extraction of
phycocyanin from Spirulina platensis. | en_US |
