Summary: Microalgal oils are being explored as a potential alternative feedstock for the production of glycerolipids such as MAGs and DAGs due to their high nutritional value and environmental advantages. While biodiesel remains a common application for microalgal lipids, the study highlights the potential for producing higher-value products like food emulsifiers from this source.

Summary: Lipid oxidation is a major cause of quality deterioration in food products, and the presence of colloidal structures and interfaces play a crucial role in this process. Micelles in emulsions and reverse micelles in bulk oils are reservoirs for antioxidants and pro-oxidants, and serve as nanoreactors where lipid oxidation reactions occur.

Summary: Thermal treatment of tea polysaccharide conjugates (TPCs) at 110 degrees C for 3 days significantly improved their emulsifying activity without affecting antioxidant activity. TPC-3d stabilized emulsions were more effective at inhibiting chemical degradation of encapsulated bioactive lipids, attributing to the antioxidant activity of conjugated phenolic groups in TPC. Results suggest that thermally-treated TPC has potential as a novel plant-based antioxidant emulsifier for encapsulating and protecting chemically labile hydrophobic compounds.

Summary: The study unraveled the crucial roles of three Chlamydomonas LACS enzymes in lipid synthesis, remodeling, and catabolism through genetic, biochemical, and physiological analyses. It highlighted the importance of lipid homeostasis in cell growth under nutrient fluctuations, with solid experimental evidence supporting the findings. Transcriptional reprogramming was not the primary factor for the observed lipid phenotypes, but rather a shift in metabolic adjustment was suggested.

Summary: Semi-continuous immobilized cultivation of Porphyridium cruentum with calcium alginate beads increased cell biomass and daily SPs productivity, and combining blue wavelength illumination further enhanced phycobiliproteins content. Nutrient deficiencies in conjunction with immobilization doubled the daily SPs productivity compared to the control. The chemical composition and biological activity of the extracellular polymeric substances produced through immobilization were similar to those of the control, suggesting the potential application of calcium alginate beads-based immobilization for continuous and high-efficiency SPs production.

Summary: This study demonstrates process intensification through lipase-catalyzed transesterification of waste cottonseed oil with ethanol under ultrasonication, achieving a maximum conversion rate of 98.7%. The optimized process conditions include an ethanol to oil molar ratio of 4.5:1, a reaction temperature of 45 degrees C, enzyme loading of 5 wt%, a reaction time of 6 h, ultrasonic amplitude of 40%, and a duty cycle of 15 s ON and 15 s OFF. The use of ultrasound enhances efficiency by reducing reaction time to 6 hours with minimal catalyst dosage and power consumption.

Summary: In this study, a green and simple bionic-immobilization method was developed for the immobilization of recombinant lipase using bio-silicification, resulting in a high immobilization efficiency and activity recovery. The bionic-immobilization significantly improved the thermal stability, storage stability, and resistance of the bionic-immobilized lipase, with key amino acid residues and molecular conformation playing crucial roles. Additionally, biodiesel production using the bionic-immobilized lipase as catalyst showed high yield and catalytic activity, demonstrating the potential of bionic-immobilization for industrial applications.

Summary: This research investigates the role of carotenoids in the oxidative stability of mixtures of fish oil and lipid extracts of two different microalgae. It finds that the initial amount of carotenoids relative to n-3 LC-PUFA is a good indicator to differentiate between oxidatively stable and unstable mixtures. The degradation of fucoxanthin, diatoxanthin, and beta-carotene during storage illustrates their antioxidative role.
