Which specific biochemical compounds in spirulina have been scientifically proven to exhibit anticancer properties?5 answersPhycocyanin, a compound found in Arthrospira spp. of cyanobacteria, has been extensively studied for its potent anticancer properties. It inhibits tumor cell proliferation, induces apoptosis through various signaling pathways, and exhibits antioxidant, antiangiogenic, and antimetastatic activities. Additionally, spirulina nanoparticles containing paclitaxel have shown promising anticancer activity against gastric cancer, enhancing overall survival in animal models when delivered intra-tumorally. Furthermore, cyanobacteria produce bioactive compounds like depsipeptides, cyclic peptides, macrolides, and fatty acid amides, which have demonstrated effectiveness against various cancer cell lines and in animal models, with some compounds showing success in human clinical trials. These findings highlight the potential of specific compounds in spirulina and cyanobacteria for developing novel and effective anticancer therapies.
What is the prebiotic effect of Spirulina?9 answersThe prebiotic effect of Spirulina, a blue-green microalgae, has been extensively studied across various research contexts, demonstrating its potential to beneficially influence the gut microbiota and overall health. Spirulina's digested biomass has been shown to selectively stimulate beneficial microorganisms such as Lactobacillus-Enterococcus and Bifidobacterium while inhibiting undesirable bacteria in the human colonic microbiota, suggesting a higher prebiotic index than fructooligosaccharides. In gluten-free bakery products, Spirulina fortification not only improved the functional potential of the food but also led to the presence of exclusive bioactives correlated with prebiotic activity.
Further research indicates Spirulina's potential as a pollen substitute for honey bees, where it produced biomarker profiles indicative of elevated nutritional states and significantly increased beneficial gut bacteria abundance, highlighting its prebiotic-like effects. In animal models, Spirulina polysaccharides (PSP) modulated gut microbiota, increasing the abundance of beneficial bacteria such as Lactobacillus, which might be related to its capacity to suppress lung cancer. Similarly, in lambs, Spirulina supplementation improved rumen fermentation and significantly altered the rumen microbiota composition, reversing changes caused by a high-fat diet.
Spirulina's rich composition of functional compounds, including polysaccharides, has been recognized for its anti-inflammatory, antioxidant, and immunomodulating properties, which contribute to its prebiotic effects. Its administration has shown efficacy in lowering blood pressure, potentially through modulation of gut microbiota. In the context of myocardial infarction, Spirulina supplementation demonstrated cardioprotective effects, which, while primarily anti-inflammatory and antioxidant, also suggest a role in gut health modulation. In dogs, dietary Spirulina supplementation enhanced immune response and gut health, indicating a stable gut microbiota. Lastly, Spirulina's dietary supplementation in poultry beneficially affected gut microbial population, serum biochemical parameters, and growth performance, highlighting its broad-spectrum prebiotic and health-promoting effects.
How is spirulina cultivated?4 answersSpirulina cultivation involves various techniques and conditions. It can be grown in mixotrophic systems using wastewater nutrients and solar energy for biomass growth. Factors influencing Spirulina growth include pH, lighting, temperature, stirring speed, and water quality. Spirulina has been successfully cultivated in black wastewater, showing potential for cost-effective and environmentally friendly practices. This blue-green alga thrives in alkaline environments and can grow abundantly in warm temperatures and tropical regions, making it a versatile species for cultivation. Innovative devices like tubular culture ducts with sensors for monitoring temperature, salinity, and pH concentration optimize Spirulina cultivation conditions for enhanced growth. Overall, Spirulina cultivation methods vary from open systems to closed photovoltaic reactors, with a focus on nutrient supply, environmental parameters, and sustainable practices.
How to extract oil from algae spirulina?5 answersOil extraction from Spirulina platensis microalgae can be achieved using various methods. One method is ultrasound-assisted extraction, which involves the use of mixed solvents such as isopropyl alcohol and n-hexane. The experiment showed that a higher yield of oil was obtained using a mixture of 40% isopropyl alcohol and 60% n-hexane, while the lowest yield was obtained using 100% n-hexane. Another method is supercritical CO2 (SCCO2) extraction, which has advantages such as lower toxicity and no solvent-liquid separation. Adding methanol as a cosolvent in SCCO2 extraction significantly increased the lipid extraction yield for Spirulina sp. and Schizochytrium sp. species. A stepwise addition of methanol was found to be more effective than a one-time addition. Additionally, extraction with supercritical CO2 without pretreatment resulted in a yield of 10 mg/g of dry biomass, while microwave pretreatment for 5 minutes increased the yield to 40 mg/g of dry biomass.
Is spirulin effective?4 answersSpirulina supplementation has shown positive effects in various aspects of health and disease. It has been found to have antioxidant, anti-inflammatory, immunomodulatory, and insulin-sensitizing properties, making it potentially beneficial for athletes. Spirulina has also been shown to improve lipid profile, reducing LDL-C, TC, and TG levels while increasing HDL-C levels. In addition, Spirulina has demonstrated efficacy in reducing the burning sensation and lesion size in oral lichen planus. Furthermore, as an adjuvant to non-surgical periodontal therapy, Spirulina has shown potential in reducing probing depth in periodontitis patients. Lastly, Spirulina supplementation has been found to lower systolic and diastolic blood pressure, particularly in hypertensive patients. Overall, the evidence suggests that Spirulina can be effective in various health conditions, but further research is needed to establish its exact benefits and mechanisms of action.
Does spirulina have anti-hypertensive effect in vivo?5 answersSpirulina has been found to have anti-hypertensive effects in vivo. Oral administration of Spirulina protein hydrolysate significantly reduced the systolic and diastolic blood pressure of spontaneously hypertensive rats. Additionally, Spirulina platensis exhibited antihyperglycemic activity and reduced elevated blood glucose levels in rats. The methanolic extract of Spirulina platensis showed antidiabetic activity by reducing the activity of α-amylase and α-glucosidase diabetic enzymes. Furthermore, the extract improved liver and pancreas histopathological disorders related to diabetes. These findings suggest that Spirulina has potential as a nutritional supplement for blood pressure control and as a treatment for diabetes and its related symptoms.
