Abstract
|
|
|
|
Carotenoids are organic pigments with antioxidant properties and are widespread in nature. Here, we isolated five microbes, each forming yellow-colored colonies and harboring C30 carotenoid biosynthetic genes (crtM and crtN). Thereafter, Lactobacillus plantarum subsp. plantarum KCCP11226, which showed the highest carotenoid production, was finally selected and the produced pigment was identified as C30 carotenoid 4,4’-diaponeurosporene. This strain exhibited the highest survival rate under oxidative stress and its carotenoid production was also enhanced after exposure to 7 mM H2O2. Moreover, it showed the highest ability to scavenge DPPH free radical. Our results suggested that L. plantarum subsp. plantarum KCCP11226, which produces 4,4’-diaponeurosporene as a natural antioxidant, may be a functional probiotic.
