ABSTRACT
As part of development for the mass cultivation of Dunaliella salina with high
-
carotene content, Dunnaleilla salina was cultivated as a model organism in outdoor ponds
at Emisal Co. (fayoum area). The objective was the optimization of operating condition
(temperature, aeration rate, sunlight, brine quality, and biomass density) production of
active biomass was optimal at temperature less than 35
oC, while higher temperature tended
to reduce motility and, eventually, growth also for brine quality, where brine has no color,
low COD value and low calcium sulphate or carbonate content is good quality for
cultivation of Dunaliella salina .
