High Protein and β-Carotene Yield of Dunaliella spp. Exposed to High Light Intensities and Nutrient Limitation
Samia K. Mikhail & Wagdy LabibNational Institute of Oceanography and Fisheries,Kayet Bey, Anfoshi, Alexandria, Egypt
Material and Methods
D. Bardawil (N.M, 15.43 & S.M, 13.04 µg ml-1)
D. Salina (N.M, 14.77 & S.M, 12.31 µg ml-1)
I- Total protein
II- Dry weight
Under stress conditions transient response in the surviving population of Dunaliella spp., including rounding of the cells, decreased motility, change in colour from green to deep orange and cessation of cell division was observed.
II- Protein contents
Essential amino acids
Dunaliella spp. is a good source for the three EAA.
