[Main elements]: Photosynthetic bacteria, ferment metabolites.

[Character]: Light yellow powder.

[Biological feature]: Photosynthetic bacteria (abbr. PSB) are the earliest procaryotic organisms on the earth, existing widely in nature, with original photosynthesis system, gram negative bacteria, distributing widely in the natural soil, paddy field, moor, lake, river, sea and etc.

Principle: the photosynthetic bacteria use light as their energy, they can use the natural organisms, sulfide, ammonia and etc. as the microorganism of supplying hydrogen and carbon source to do photosynthesis under the condition of anaerobic light or the condition of aerobic dark. The protein content in the cell dry matter is up to over 60 percent, the consist of their protein and amino acid is relatively complete, there are various vitamins in the cells, especially vitamin group B is rich, the contents of B2, folic acid, pantothenic acid, biotin are higher too, meanwhile, they have plenty of physiological activators like carotenoid, coenzyme Q and etc.

[Main functions]:

1. The product can clean water:it can degrade the residue of food, feces and other organisms in water, absorb and use the harmful substances in water like ammonia nitrogen, nitrite, hydrogen sulfide.

2. To be used as the starter feed of the aquatic animals and feed additive: the volume of PSB is one twentieth of chlorella; it is exactly suitable to be the starter feed of the just born seeds, and can greatly increase the surviving percent of the seeds. It can be added into the feed, promote the digestion and absorption to the feed of the aquatic animals, increase the using of the feed, reduce the food coefficient, and obviously increase the growing speed of the aquatic animals.

3. To reduce the diseases happened to the aquatic animals: it can inhibit the growing and reproduction of the harmful bacteria, reduce the amount of the harmful virus, so that reduce the disease.

4. To culture the beneficial algae: after using the PSB in water, the diatom and chlorella become the advantaged algae, however the harmful substances are inhibited like cyanobacteria and etc.

5. To improve the soil: provide the amino acid and nucleotide for the plants, to improve plant disease tolerance, and improve soil structure and fertility.
