Research Progress in Antioxidant Activity of Anoxygenic Photosynthetic Bacteria

Anoxygenic photosynthetic bacteria not only are abundant in nutritional components and bioactive materials,but also possess the functions of biological nitrogen fixation,production of hydrogen and degradation of toxic substances.Therefore,anoxygenic photosynthetic bacteria have been gain tremendous attention.In this paper,taxonomy,antioxidant mechanisms and applications of anoxygenic photosynthetic bacteria are reviewed.Meanwhile,the current problems are also discussed.
