“…On the contrary, in Dunaliella salina Teodoresco, the saturated fatty acid level in the cell decreased, and the highly unsaturated fatty acid (HUFA) level increased with an increase in NaCl concentration [54]. The direct in uence of salt on the processes involved in electron transport and photophosphorylation results in a decrease in the quantum e ciency of photosynthesis [55].…”

The biochemical compositions of microalgae are altered with the change in pH, temperature, photoperiod, salinity, and metal content in the culture media. This study aimed to evaluate the effect of different environmental shocks on the lipid, EPA, and DHA fatty acids levels in Chlorella sp. The algae were cultivated for 12 days using a Guillard medium for biomass production. At this stage, algae were reared under eight shock conditions for six days; T1 (control), T2 was subjected to salinity+pH+starvation, T3 to salinity, T4 to starvation, T5 to pH+starvation, T6 to salinity+pH, T7 to salinity+starvation and T8 to pH shocks. The samples were collected at the end of the dark or light period. The results revealed that the lipid content of Chlorella sp. was signi cantly affected by darkness in T6. The lipid content under salinity shock during the light period was signi cantly lower than T5 on day 18. The Arachidonic acid (ARA) and EPA in T4 and DHA in T6 during the dark period exhibited signi cant differences compared to other groups (p<0.05). Based on the results obtained highest lipid production and DHA synthesis in chlorella sp. were induced on day 18 during the dark period by T4 and T6, respectively.

Microalgae hold great promise as a source of biofuels and biochemicals. The main obstacles to their industrial application are the high cultivation and downstream costs related to media and harvesting. In the work, we explored the multiple potentials of seawater to address key issues relating to the cultivation of Scenedesmus obliquus. Seawater can sufficiently replace some of the key elements in BG11 medium such as MgSO4, CaCl2, and NaCO3, and its use can significantly reduce the quantity of water required for the preparation of culture media. Among our results, the total chlorophyll content in cells grown in modified BG11 using 10 % (v/v) seawater was increased 1.47-fold without sacrificing biomass or lipid production. More than 70 % of the total algal biomass was auto-flocculated within one hour when cells were grown in seawater-supplemented media, which compares very favorably with a yield of only 3 % from cells grown in BG11.
