The culture device comprises a fermentation tank, an air input unit,a nitrogen input unit, a redox potential electrode unit, a pH value control unit and a master control unit, wherein a photosynthetic bacterium liquid is injected into the fermentation tank, the air input unit and the nitrogen input unit are connected to the interior of the fermentation tank through a pipeline, the redox potential electrode unit is connected to the interior of the fermentation tank, the pH value control unit is connected to the fermentation tank through a pipeline, and the master control unit controls the air input unit, the nitrogen input unit and the pH value control unit according to the parameter information of the fermentation tank, so that the photosynthetic bacterium in the fermentation tank reaches the highest growth rate. The invention further discloses a culture method for the photosynthetic bacterium. A redox potential electrode is used to monitor the culture process of the photosynthetic bacterium online, so that the growth rate of the bacterium and the utilization of a substrate are improved.

Description

technical field [0001] The invention relates to the technical field of industrial biology, in particular to a culture device and a culture method for photosynthetic bacteria. Background technique [0002] At present, the cultivation of photosynthetic bacteria, such as Rhodospirillum rubrum, is rough and the technology is backward. It is impossible to monitor the cultivation of photosynthetic bacteria online in real time, and it is impossible to make timely adjustments to the growth process of photosynthetic bacteria. Therefore, the final cell growth rate is low, the substrate utilization is low, and the production cost is high. Contents of the invention [0003] The purpose of the present invention is to solve the above problems, provide a photosynthetic bacteria cultivation device and cultivation method, utilize oxidation-reduction potential electrodes to monitor the cultivation process of photosynthetic bacteria on-line, improve the growth rate of the bacteria and the ut...
