It is known that Spirulina extracts have strong antioxidant activities since it contain diverse antioxidants such as phytocyanin, β-carotene, vitamin E and other carotenoids. In order to obtain an enhanced antioxidant activity of Spirulina, in this study, Spirulina extracts were fermented by Lactobacillus plantarum P23 and Bacillus subtilis TP6. The resulting fermented supernatants were analyzed for their antioxidant activities by DPPH(2,2-diphenyl-1-picrylhydrazyl) method. The results indicated that fermentation process significantly enhanced total antioxidant activities.
Increased levels of UV-induced TNF-α and IL-6, two of known proinflammatory cytokines, were reduced back to normal level even by treatment of all three of the spirulina extracts. However the
spirulina extracts fermented by Lactobacillus plantarum P23 showed the same antiinflammatory effect at 0.01% while the unfermented extract was needed 0.1%. The result suggested that the fermentation process enhanced the antiinflammatory activities at least 10 X higher than the simple extract. In conclusion, the fermented Spirulina extracts are expected to be used as
cosmeceuticals.
