Summary: The study shows that utilizing Fe3O4 nanoparticles can significantly increase the biomass and total lipid production of microalgae. By initially exposing the algae to low concentrations of Fe3O4 nanoparticles and then treating them with higher concentrations, growth and lipid accumulation can be effectively promoted.

Summary: Biomass pyrolysis has been hindered by the formation of NOx precursors, mainly from protein pyrolysis. The effect of lipids on this process is unclear. In this study, proteins and lipids were extracted from chlorella and sewage sludge to investigate their thermal decomposition characteristics, thermodynamic properties, kinetic parameters, and reaction mechanisms. The results showed that lipids restrict the pyrolysis of sludge protein, while there was no significant difference in the pyrolysis of chlorella protein with or without lipids.

Summary: In this study, GXU-A4 was isolated from an aerobic tank treating molasses vinasse (MV) and identified as Desmodesmus sp. It exhibited good growth with high lipid content and chemical oxygen demand (COD) when grown using MV and the anaerobic digestate of MV (ADMV) as the growth medium. GXU-A4 demonstrated high fouling tolerance, rapid growth rate, biomass accumulation, and nutrient removal ability in MV and ADMV, indicating its potential for MV recycling.

Summary: This study investigates the potential of UV/gamma-radiation for enhancing lipid production in Chlorella sorokiniana. The results show that growth, chlorophyll content, and photosynthesis efficiency decrease in a dose-dependent manner after irradiation. Transcriptional profiling reveals the modulation of photosynthetic and DNA repair/replication genes under UV and gamma radiation. Upregulated fatty acid biosynthesis genes coincide with increased total lipid accumulation under UV and gamma radiation. Ascorbic acid supplementation reduces UV and gamma radiation-induced lipid accumulation, indicating ROS as a major driver. Fatty acid analysis shows that UV favors the accumulation of saturated lipids, while gamma radiation treated lipids have a higher accumulation of essential omega-3 fatty acid.

Summary: This study compared the performance of Monoraphidium sp. and Chlorella sorokiniana in the energy conversion process, finding that Chlorella sorokiniana has higher yield and more favorable fatty acid profile. The use of biodiesel showed high lipid recovery and lower CO and HC emissions, but slightly higher nitrogen oxides and carbon dioxide emissions.

Summary: This study generated mutant strains of marine microalgae, Chlorella vulgaris, through UV light exposure and 5'fluorodeoxyuridine treatment, which enhanced lipid production and had suitable fatty acid profile for biodiesel production. Transcriptome analysis revealed upregulation of genes related to fatty acid biosynthesis and photosystems in the mutants under outdoor conditions, correlated with the increased lipid production and biomass. The study provides valuable insights into specific targets for enhancing biomass and lipid production for biodiesel.

Summary: The study found that melatonin significantly promoted lipid accumulation in Monoraphidium sp. QLY-1 under salinity stress by upregulating lipogenesis-related genes, reducing oxidative stress, and promoting autophagic activity. Furthermore, the combination of melatonin and the autophagy activator rapamycin further increased lipid content, suggesting a valuable strategy for enhancing lipid production in microalgae.

Summary: This study investigates the effects of water content, operating pressure and temperature on supercritical CO2 extraction of lipids from Chlorella vulgaris microalgae. The highest extraction yield was obtained with freeze-dried microalgae at 40℃ and 200 bar. However, extracts obtained at 40℃ and 250 bar had the highest fatty acid content, while those obtained at 60℃ and 250 bar had the highest cetane number and oxidative stability. Water in the initial biomass had a negative impact on total extraction yield, but promoted the extraction of fatty acids, particularly monounsaturated ones.

Summary: Meteorological factors such as wind direction, radiation, and the Oceanic Nino Index were identified as the main drivers of phytoplankton biomass variation in Lake Mangueira. The study found that ENSO events caused significant changes in physical, chemical, and meteorological parameters, leading to differences in phytoplankton biomass between La Nina years and periods without events. Including meteorological variables in limnological studies is crucial for understanding productivity patterns in aquatic ecosystems.
