Photosynthetic bacteria can tolerate high concentration of organic wastewater, phenol, cyanide and other poisons because of its strong adaptability, and have certain tolerance and decomposition ability, and have strong decomposition and transformation ability. The application of photosynthetic bacteria in aquatic products is increasing, which makes it play a great role in pollution-free aquaculture.

The following are the functions of photosynthetic bacteria such as Gold Medal, for reference only:

1, purifying water quality

After photosynthetic bacteria are applied to water, it can degrade the residual organic matter such as feed and fish manure in water. At the same time, it can also absorb and utilize harmful substances such as ammonia, nitrite and hydrogen sulfide in water. The application of photosynthetic bacteria can effectively avoid the accumulation of solid organic matter and harmful substances, and play a role in purifying water quality.

2. Feed additives

Photosynthetic bacteria is a kind of bacteria with rich nutrition and high nutritional value. This bacterium is rich in amino acids, folic acid and B vitamins, especially vitamin b 12 and biotin, as well as the physiologically active substance coenzyme Q. The volume of photosynthetic bacteria is one twentieth of that of Chlorella vulgaris, which is especially suitable as the open bait for newly hatched larvae. Using photosynthetic bacteria as open bait can greatly improve the survival rate of fry. Photosynthetic bacteria can also be added to feed as feed additives. Enzymes contained in photosynthetic bacteria can promote fish's digestion and absorption of feed, improve feed utilization rate, reduce feed coefficient and significantly improve fish's growth rate.

3. Reduce fish diseases

After the photosynthetic bacteria were applied to the water, they quickly propagated into the dominant flora in the water, which not only improved the water quality, but also inhibited the growth and reproduction of harmful bacteria and reduced the number of harmful bacteria, thus reducing the occurrence of fish diseases. Photosynthetic bacteria are very effective in preventing diseases.

4. Cultivate beneficial algae

After photosynthetic bacteria are applied to the water, algae that fish like to eat, such as diatoms and Chlorella, become dominant algae, while harmful algae such as cyanobacteria are inhibited. Photosynthetic bacteria can make great use of ammonia nitrogen in water, and can effectively avoid "water bloom", such as the reproduction of cyanobacteria.
