Carotenoids, which have biologically beneficial effects and occur naturally in microorganisms and plants, are pigments widely applied in the food, cosmetics and pharmaceutical industries. The compound 4,4'-diaponeurosporene is a C 30 carotenoid produced by some Lactobacillus species, and Lactobacillus plantarum is the main species producing it. In this study, the antioxidant activity of 4,4'-diaponeurosporene extracted from L. plantarum subsp. plantarum KCCP11226 was examined. Maximum carotenoid content (0.74 ± 0.2 at A 470 ) was obtained at a relatively low temperature (20°C). The DPPH radical scavenging ability of 4,4'-diaponeurosporene (1 mM) was approximately 1.7-fold higher than that of butylated hydroxytoluene (BHT), a well-known antioxidant food additive. In addition, the ABTS radical scavenging ability was shown to be 2.3- to 7.5-fold higher than that of BHT at the range of concentration from 0.25 mM to 1 mM. The FRAP analysis confirmed that 4,4'- diaponeurosporene (0.25 mM) was able to reduce Fe 3+ by 8.0-fold higher than that of BHT. Meanwhile, 4,4'-diaponeurosporene has been confirmed to be highly resistant to various external stresses (acid/bile, high temperature, and lysozyme conditions). In conclusion, L. plantarum subsp. plantarum KCCP11226, which produces 4,4'-diaponeurosporene as a functional antioxidant, may be a potentially useful strain for the development of functional probiotic industries.
