A doctoral dissertation entitled “The Effect of Some Environmental Factors on the Production of Fatty Acids (EPA-DHA) in Certain Types of Algae and Evaluating Their Cytotoxic Activity Against Certain Cancer Lines” was discussed at the College of Education, Al-Qadisiyah University. The dissertation was presented by researcher Hamida Ayal Maktoof and supervised by Assistant Professor Dr. Raed Kadhim Abd.

The most important findings indicate that the alga Nannochloropsis ocenica possesses genetic and enzymatic flexibility that allows it to outperform the algae Clorella vulgaris and Spirulina platensis when salt stress is combined with light intensity. Furthermore, the efficiency of fatty acid elongation pathways is linked to the availability of photosynthetic products (ATP and NADPH), making light the most important determining factor in the quality of the resulting fatty acids.
