Abstract:

In present paper, the structure and function of carotenoids in two pigment protein complex including light-harvesting system and the reactor center are reviewed. The biosynthetic pathways of carotenoids and inhibition site of carotenoids synthetic pathways in photosynthetic bacteria are also described in this paper. Some carotenoids synthetic gene have been cloned and filtrated by genetic techniques, the synthetic enzyme genes and mechanisms of carotenoids biosynthesis in photosynthetic bacteria regulation are elucidated. The influence of carotenoids on biohydrogen production and the presently existing problems of carotenoids are also analyzed and discussed.

Key words: Photosynthetic bacteria, carotenoids, biosynthesis, metabolism regulation, biohydrogen production
