The core significance of the photosynthetic bacteria value-added culture experiment is to obtain high-purity and highly active bacterial cells on a large scale. This provides the possibility for its wide application: as a water purification agent and feed additive in aquaculture; Used as a biological fertilizer in agriculture to promote plant growth; It can also produce high-value substances such as single-cell protein, coenzyme Q10, carotenoids, etc., with great potential in the fields of environmental protection, energy, and biotechnology.

Common configurations:
1. Temperature: 25-30 ℃ (for example, the optimal temperature for red snail bacteria is 28 ℃, and for blue bacteria it is 30-35 ℃)
2. Speed: 50-150rpm
3. Light intensity: 2000-5000 lux (anaerobic photosynthetic bacteria such as purple sulfur bacteria require weak light (500-2000 lux), strong light will inhibit their photosynthetic enzyme activity; Aerobic bacterial strains can tolerate higher levels of light exposure (such as cyanobacteria reaching up to 10000 lux)
