Photosynthetic bacteria (PSB) can be divided into four families: Rhodosporium, Chromobacterium, Chlorobacillus and filamentous green bacteria. * * * The same feature is that it absorbs various spectra under anaerobic illumination, uses light energy to make organic matter as hydrogen donor, and fixes carbon dioxide or low-fat organic matter as carbon source to grow and develop, and its growth process does not produce oxygen. Besides eliminating hydrogen sulfide and ammonia nitrogen in water, it is also rich in amino acids, vitamin B 12, folic acid, bacteriocin, carotene and coenzyme.

Function:

1: reduce the contents of organic matter, chemical oxygen consumption, ammonia nitrogen and sulfide. Increase dissolved oxygen and improve water environment.

2. Bacteria are rich in various nutrients, which can fully improve feed efficiency, reduce feed coefficient and improve the meat quality and flavor of aquatic products.

3. Photosynthetic bacteria in dry land can significantly improve the growth performance of aquatic animals, and gain weight obviously, so it will be listed in advance.

4. Improve the content and immunity of serum immunoglobulin of aquatic animals, and inhibit the growth of pathogenic bacteria.

Principle:

1: transforming animal feed and its harmful gases (H2S), amines, lower fatty acids, etc. It is transformed into its own nutrients, thus reducing the contents of organic matter, chemical oxygen consumption, ammonia nitrogen and sulfide in water. Increase dissolved oxygen and improve water environment.

2. Rich in amino acids, nucleic acids, B vitamins, coenzyme Q, physiologically active substances and natural pigments such as carotenoids and tomato red, these nutrients can improve the meat quality and taste of aquatic products.

3. Harmful hydrogen sulfide, amines, lower fatty acids, etc. produced by feces and leftover feed can be transformed into normal nutrient elements and dissolved in bacteria.

4. It can improve the content and immunity of serum immunoglobulin in aquatic animals, secrete and produce protein antagonists outside cells, and inhibit the growth of pathogenic bacteria.

How to save:

The growth and reproduction of photosynthetic bacteria are not only related to nutritional conditions, but also to light and temperature. The temperature is suitable, even if the light is insufficient, it will grow, but the speed is slow; The temperature is low, even if there is enough light, it is difficult to stop growing; If the temperature is too high, it will age and die. Therefore, temperature is the key to preserve bacterial liquid.

Use skills:

1: Used when the water temperature is above 20℃. Be careful not to use it in rainy days.

2. When applying manure or chemical fertilizer in the pond, the effect of applying photosynthetic bacteria is more obvious. In particular, it can avoid the shortcomings of too much chemical fertilizer and difficult control of water quality, and can prevent the deterioration of water quality caused by algae aging.
