Abstract

Abstract:

Photosynthetic bacteria have been paid more and more attention to the application in wastewater treatment due to its non-toxicity, quick breeding, easy artificial cultivation and no secondary pollution producing. The physiological and biochemical basis of bioaccumulation heavy metal with photosynthetic bacteria is introduced, and the application of photosynthetic bacteria to the treatment of heavy metal wastewater in recent years is reviewed. Furthermore, the resistance and bioaccumulation capacity of photosynthetic bacteria to different heavy metal ions, and the effects of environmental factors on bioaccumulation performance are discussed. At the end, the prospect of biotreatment of heavy metal wastewater by photosynthetic bacteria is forecast.

Key words: photosynthetic bacteria, heavy metal, wastewater, bioaccumulation
