Summary: In this study, the de novo synthesis of triacylglycerol (TAG) in Coccomyxa sp. Obi strain under nitrogen (N)-replete and N-limiting conditions was analyzed. The results showed that TAG synthesis is limited by fatty acid supply under N-replete conditions, while it is enhanced under N-limiting conditions. The expression of the acyl-ACP thioesterase, FAT1, involved in releasing fatty acids from acyl-ACP, was induced under N-limiting conditions. Furthermore, the turnover of TAG was significant under N-replete conditions. The slow conversion of diacylglycerol to TAG partly explained the slower rate of TAG synthesis compared to polar lipid synthesis under N-limiting conditions.

Summary: The continued use of petroleum-derived fuels is unsustainable and microalgae is a promising source of renewable biofuel. Microalgae have higher oil productivity and do not require agricultural land. A developed microextraction method allows for efficient examination of lipid content with time and resource saving.

Summary: This study utilized hypotonic osmotic shock as a treatment step to enhance the recovery of biofuel-convertible lipids and proteins from lipid-rich saltwater Nannochloropsis gaditana slurries. The osmotic shock treatment weakened the structural integrity of the slurries and improved the efficiency of subsequent mechanical or chemical cell disruption technologies.

Summary: The inclusion of vegetable oils in aquafeeds has altered the fatty acid composition of the diets, leading to changes in the intracellular fate of these fatty acids in intestinal cells. In an in vitro study using rainbow trout intestinal epithelial cells, oleic acid was found to accumulate in cytosolic lipid droplets to a greater extent compared to other fatty acids. The carbon chain length and saturation level of fatty acids play a role in determining their intracellular metabolism.

Summary: This study evaluates the feasibility of using microalgae as oil feedstock for biodiesel production. The results show that oil extracted at room temperature has a higher biodiesel conversion yield compared to high-temperature extraction. The potential of using Chlorella vulgaris for biodiesel production is low, but enzymatic biodiesel production from microalgae represents a promising avenue for sustainable energy generation.

Summary: Microalgae present a promising alternative for future biofuel production, offering higher productivities per unit area and not depending on fertile soils or freshwater. Studies suggest that microalgal cultivation could require less than 1.1% of global land area, mainly in dry regions, with potential in regions like Africa, the Middle East, South America, the Caribbean, and Oceania for biofuel production.

Summary: This study explores the use of "sea-thermal" treatment of the microalgae Chlorella Vulgaris to produce energy-dense biofuels and value-added liquid products. The processing conditions and reaction medium were found to significantly affect the yields and properties of the products. Low temperatures and short reaction times favored the formation of biocrude, while high temperatures and prolonged processing times promoted the repolymerization of the biocrude to hydrochar. The salinity of the seawater also played a role in these transformations.

Summary: Microalgae are a promising feedstock for renewable fuels and their oil accumulation can be enhanced by exposure to nanoparticles. However, previous studies have used mostly non-biodegradable nanoparticles, limiting their application in biofuel production. This study reports the use of biodegradable engineered resin nanoparticles (iBCA-NPs) to enhance TAG and starch accumulation in Chlamydomonas reinhardtii. Short exposure to iBCA-NPs increased cellular TAG and starch contents significantly, with improved TAG production and increased fatty acid content. The addition of iBCA-NPs also increased cellular reactive oxygen species (ROS) content and upregulated the activities of antioxidant enzymes. The study demonstrates a useful approach to enhance energy-rich reserve accumulation in microalgae.

Summary: The use of indigenous microalgae strains for wastewater treatment and biofuel production is important for effective applications and carbon sequestration. Researchers successfully isolated indigenous microalgae strains from samples collected on coastlines and islands in South Korea, and found that one strain had better growth and pollutant removal abilities in wastewater compared to artificial growth medium. Additionally, this strain was able to fix CO2.
