“…Microalgae can be the strongest substitute for fossil fuel in a cost-effective justifiable way and can also lead to decreased greenhouse gas production 14 , 15 . The high photosynthetic ability of microalgae has not only useful for lipid growth but it is also useful as a capable practice for carbon sequestration, oxygen production and N cycling 16 , 17 . Algae have the ability to alter their growth rate and their biochemical composition in various physiochemical states 18 .…”

The biofuels are receiving considerable attention as a substitute for petro diesel. For microalgae, the cell density or biomass and lipid contents are key components for biodiesel production. This study was conducted to develop favorable culture conditions for Dunaliella salina to maximize its biomass and lipid accumulation. The effect of salinity (0.5 to 2.5 M NaCl) on the cell population, biochemical composition, and lipid output of Dunaliella salina was examined under a controlled environment for 21 days. Maximum growth (6.57 × 107 to 7.17 × 107cells mL−1) potentials were observed at 1.5 to 2 M NaCl. The photosynthetic pigments and carbohydrates also showed trends similar to growth. The maximum carotenoid level (5.16 mg L−1) was recorded at 2 M NaCl. Almost all physicochemical parameters increased with increases in salinity, biomass (1231.66 ± 1.26 mg L−1) and lipid content (248.33 mg L−1), as recorded at 2 M NaCl. Based on fluorescence intensity, the highest values (11.84 × 107cells/ml) of neutral lipids and total lipids (22.28%) were recorded at optimum salinity levels. The present study suggests that a high biomass and lipid accumulation of Dunaliella salina SA 134 could be obtained at the 2 M NaCl level.

“…In addition, a high-pH environment seriously affects the photosynthetic reaction process and cell uptake of nutrient salts, which leads to a decrease of microalgae biomass yield. Therefore, during the cultivation of the algae, the pH should be stabilized and managed to be neutral (pH = 6-8) [154].…”

“…During the experiment, the water pH values in the upper and lower layers of the ber membrane of experimental group A showed a trend from rising to decline between 7 and 7.5; the pH values of the upper and lower water bodies of experimental group B declined rstly and then increased between 7 and 7.5. The insigni cant changes in pH can be attributed to the factors as follows: the CO 2 consumption by the growth of algae in the water body, leading to an increase in pH value (Tsai et. al, 2012).…”

In this study, laboratory experiments were used to compare the effects of two LED light sources (blue and red) combined with fiber membranes on the increase of Dissolved Oxygen (DO) in eutrophic water bodies for improvement of water quality. The results showed that the application of these two LED light sources can increase the DO concentration and oxidation-reduction potential (ORP), and eliminate the NH4+-N in water bodies and the phosphorus release from the sediment, resulting in the improvement of sediment. Specifically, the blue LED light source is more benefitable to the increase of the DO concentration than the red LED light source. After 28 days, the DO concentration increases to 10 mg/L, and the redox potential is higher than 50 mV with the elimination of NH4+-N. This study illustrated that LED light sources can significantly increase the DO and effectively improve the water quality in eutrophic water bodies.
