Properties of antioxidants produced by Rhodobacter sphaeroides

This study investigated the properties of antioxidants produced by Rhodobacter (R.) sphaeroides, a purple, non-sulfur photosynthetic bacterium. R. sphaeroides was fractionated into water-soluble and ethanol-soluble fractions, and the ethanol-soluble fraction showed stronger activity. Light irradiation significantly decreased the antioxidant activity of the ethanol fraction. The absorption spectra of the ethanol fraction...
