Summary: The umami compounds in the acid-hydrolysate of Spirulina were investigated in this study. The Spirulina hydrolysate was found to have a higher umami intensity compared to unhydrolyzed one. A specific umami fraction was obtained by ultrafiltration and chromatography, containing high concentrations of succinic acid and free L-glutamic acid, as well as abundant glutamyl peptides.

Summary: Microalgae, which play critical roles in the food web and biogeochemical cycling, are commercially exploited for the compounds they produce. This study investigated the effects of microplastic contamination on Spirulina, a widely distributed and commercially important cyanobacterium. The results showed that increasing concentrations of microplastics led to a decrease in growth rate and photosynthetic activity, as well as oxidative stress and production of proline. Microplastics were observed to adhere or aggregate around fragmented regions, potentially providing a mechanism for internalization.

Summary: This study presents a simple and cost-saving approach to selectively recover high-added value compounds from Spirulina platensis biomass using biocompatible and industrially approved solvents. Spectrophotometric analysis detected the concentration and yield of each pigment in the liquid extract, while CIELab parameters were used to analyze the decolorized protein-rich biomass. The study successfully obtained a concentrated and food-grade C-PC extract as well as a bright decolorized protein-rich biomass.

Summary: The study demonstrated the potential therapeutic effect of Spirulina platensis against MC-LR-induced toxic effects in male Wistar rats, by alleviating oxidative damage in liver and kidneys, cardiotoxicity, and neurotoxicity. Spirulina restored normal levels of serum markers and normalized tissue antioxidant biomarkers, mitigating organ toxicities induced by MC-LR.

Summary: This study assessed the structure, composition, cytotoxicity, and in vitro hypoglycemic activity of a polysaccharide from Spirulina platensis and its degradation fragments. The polysaccharides showed inhibitory effects on alpha-glucosidase, with PSP3 exhibiting the best efficacy. MTT assays demonstrated no cytotoxic activity of the polysaccharides, but they enhanced glucose uptake capacity. PSP3 showed the best in vitro hypoglycemic activity.

Summary: This study used pancreatin and pepsin to extract bioactive peptides from Spirulina platensis protein and evaluated their techno-functional and antioxidant characteristics. The results showed that pepsin hydrolysates had higher hydrolysis and antioxidant activity compared to pancreatin hydrolysates. The hydrolysates also reduced lipid oxidation in emulsions. The digested peptides retained their antioxidant activity. H-Pep from Spirulina algae could be a promising protein source for food products with good nutritional value.
