Photosynthetic bacterium culture medium as well as preparation method and application thereof

The invention provides a photosynthetic bacterium culture medium as well as a preparation method and application thereof, and belongs to the technical field of bacterium culture media. The photosynthetic bacterium culture medium comprises a traditional Chinese medicine extract and a basic culture medium. The traditional Chinese medicine extract is added into the photosynthetic bacterium culture medium, and compared with a traditional method for obtaining efficient photosynthetic bacteria by changing external conditions and metabolic mechanisms, the photosynthetic bacterium culture medium can increase absorption of nutrients by the photosynthetic bacteria and improve cell activity by accelerating cell metabolism, so that the photosynthetic bacteria can be cultured more efficiently, and the yield of the photosynthetic bacteria is increased. Therefore, the growth speed of the photosynthetic bacteria is promoted, and the photosynthetic bacteria are high in growth speed and high in concentration. 本发明提供一种光合细菌培养基及其制
