Summary: The present study focuses on the recovery of high-added value bioactive components from Chlorella vulgaris through microwave-assisted extraction (MAE). The optimal conditions for extraction were determined, and the results showed that MAE and SFE methods can achieve extracts of competitive or even better quality under significantly shorter extraction duration compared to the conventional solid-liquid extraction (SLE) method.

Summary: This study investigated the impact of adding different vitamins, including thiamine, riboflavin, pyridoxine, and ascorbic acid, on the growth, metabolite content, and antioxidant activity of Chlorella vulgaris. The results showed that thiamine had the greatest effect, leading to increased biomass and antitumor activity in vitro. Therefore, adding vitamins to the growth medium is necessary for enhancing the growth and metabolite production of Chlorella vulgaris.

Summary: Dietary supplementation of C. vulgaris effectively enhanced the intestinal antioxidant capacity and immune status of M. salmoides. It increased albumin and total protein contents, as well as the levels of glutathione and glutathione peroxidase. However, excessive supplementation inhibited superoxide dismutase activity. Transcriptome analysis revealed changes in gene expression related to intestinal immunity and antioxidant parameters.

Summary: The study found that immobilization technology can effectively protect microalgae from CBZ toxicity and improve the removal of CBZ, especially at high concentrations (> 50 mg/L). Biodegradation was the dominant pathway for microalgae to remove carbamazepine, indicating the potential of using immobilized microalgae in high concentration wastewater treatments.

Summary: This study evaluated the efficiency of lipid extraction from Chlorella vulgaris and compared the effects of food-grade ethanol, ultrasound-assisted ethanol, and dichloromethane/methanol. The results showed that ultrasound-assisted ethanol and dichloromethane/methanol had the highest extraction yields, and the fatty acid profiles were identical among all extracts. However, the polar lipidome of the ethanol extracts was significantly different from the other two extracts. These findings are important for obtaining high yields of omega-3 and omega-6-rich extracts from C. vulgaris for food applications.

Summary: The research found that arsenic toxicity to marine microalgae was enhanced under phosphorus-limited conditions. Phosphorus supply significantly altered the effect of arsenic on the light-harvesting efficiency of photosystem. Additionally, insufficient phosphorus supply resulted in an enhanced level of membrane integrity loss, facilitating arsenic entering cells and leading to stronger toxicity to the algae.

Summary: This study aimed to recover high-added value compounds from Chlorella vulgaris through supercritical fluid extraction (SFE) with CO2. The effects of extraction temperature, pressure, and solvent flow rate on yield, antioxidant activity, and content of phenolics, chlorophyll, and carotenoids were investigated. SFE optimization led to improved antioxidant activity and yield compared to conventional ethanol extraction, despite the lower yield. The addition of a co-solvent further enhanced both the antioxidant activity and yield of the extract.

Summary: This study investigated the production capacity and antimicrobial activity of silver and gold nanoparticles by Chlorella vulgaris from Al-Ahsa, KSA. The results showed that the silver nanoparticles had the strongest antibacterial effect. By isolating and observing the RNA changes, it was suggested that the synthesis of nanoparticles may involve both biotic and abiotic processes. The use of nanosilver particles as antibacterial agents is recommended.

Summary: This study compared the fatty acid and lipid profile of four commercialized strains of Chlorella vulgaris and assessed their antioxidant and anti-inflammatory properties. Results showed differences in lipid composition and fatty acid profile among the strains, with C-Auto having higher lipid content and omega-3 polyunsaturated fatty acid levels, while C-Hetero, C-Honey, and C-White had higher omega-6 polyunsaturated fatty acid levels. All extracts exhibited antioxidant and anti-inflammatory activity, with C-Auto showing the greatest potential. These findings suggest that different strains of C. vulgaris can be selectively utilized as a source of value-added lipids for various food and nutraceutical applications.

Summary: This study investigates the potential toxicity of zinc oxide nanoparticles (ZnO NPs) and samarium-doped ZnO NPs (Sm/ZnO NPs) on the green microalga Chlorella vulgaris. The results show that both ZnO and Sm/ZnO NPs induce concentration-dependent cytotoxicity, including reduced cell growth, decreased photosynthetic pigment contents, and deformation in the cellular morphology. Sm-doping plays a significant role in enhancing the toxicity of ZnO NPs on C. vulgaris cells.

Summary: Ultrasound-Assisted Pressurized Liquid Extraction (UAPLE) and Nanofiltration (NF) in 70% ethanol were found effective in recovering and concentrating bioactive compounds, mainly isoorientin, from passion fruit rinds. However, membrane surface fouling was observed during filtration process, leading to reduced permeate mass fluxes. Overall, integrated UAPLE and NF process shows promise for phenolic compounds recovery from passion fruit rinds.

Summary: Pitangueira leaves were extracted using aqueous infusion (AI) and pressurized liquid extraction (PLE). LC-MS identified 54 compounds in the extracts. PLE-W:E extract had higher concentrations of phenolic acids and tannins, while PLE-E extract had higher concentrations of flavonoids. All extracts exhibited antioxidant, antibacterial, and allelopathic activities, with PLE extracts showing more regular activity.

Summary: F-420 is a crucial cofactor produced by some Archaea and Eubacteria, but not by commonly used industrial bacteria like E. coli. By utilizing metabolic modeling and optimizing precursor availability, researchers were able to improve F-420 production in E. coli by 40-fold, establishing it as an industrial production system and enabling the use of F-420-dependent enzymes for biocatalysis and protein engineering.

Summary: Asymmetric reduction by ene-reductases has been extensively studied, with the Old Yellow Enzyme (OYE) family being the most researched. However, the limited substrate range and stereocomplementary pairs of current ene-reductases necessitate the development of a complementary class. Flavin/deazaflavin oxidoreductases (FDORs) that use F-420 as a cofactor have gained attention due to their stereocomplementarity with OYEs. In this study, the activity of eight FDOR-B enzymes was investigated, comparing their specific activity, kinetic properties, and stereoselectivity with FDOR-A enzymes and OYE family.
