College of Science, University of Thi-Qar discussed a master dissertation on increasing in fatty acid production in some types of algae under different growth conditions by the postgraduate student, Mrs. Zahraa Muhammad Abd Al-Kadhim.

The dissertation aimed at collecting several types of algae from the local environment, characterizing them morphologically and microscopically and purifying them to obtain sufficient biomass.

The dissertation reviewed collecting samples from the Tigris and Al-Gharraf rivers in Qalaat Sukkar district in Thi-Qar Governorate, and then isolating, cultivating and purifying algae (Chlorella) and (Oedogonium), which are green algae (Chlorophyta), (Lyngbya) and (Spirulina platensis), which are green algae. Cyanophyta (Spirulina platensis) was used to compare its biochemical content with the studied algae and multiplied on the basic culture medium (Chu-10, BG-11) to conduct chemical analyzes for it, as its biochemical content such as proteins, fats, carbohydrates and fatty acids was determined.

The dissertation recommended knowing the effect of other environmental factors on different types of microalgae that are common in our local environment, especially those of economic importance due to the necessity and importance of these fatty acids, especially omegas of all kinds.
