What are nitrifying bacteria, nitrifying bacteria have a bleating effect

Nitrifying bacteria are autotrophic bacteria that include two completely distinct metabolic groups: nitrosomonas and nitrobacter, which include morphologically distinct bacilli, cocci and spirochet. Nitros-acid bacteria include bacteria in the genera Nitrosomonas, Nitrosococcus, Nitrosspironium, and Nitrosophylloidae.

Nitric acid bacteria include bacteria in the genus Nitrobus, Nitricocci, and Nirrate. Both types of bacteria are obligate aerobic bacteria, and oxygen is used as the final electron acceptor during the oxidation process. Most of them are obligate autotrophic and cannot grow on organic media, such as nitrosomonas, nitrosospira, nitrosococcus, ni-trosolobus, nitrospina, nitrococcus, etc.

Only a few are facultatively autotrophic and can also grow on certain organic media, such as some strains of Nitrobacterwinogradskyi.

In terms of morphology, there are also diverse, such as spherical, rod-shaped, spiral-shaped, etc., but all of them are spor-free gram-negative bacteria; Some have flagella that can move, such as nitrosylated leaf bacteria, which move by flagella around the body; Some flagella are immotile and inmovable, such as nitrifying stingers. It is generally distributed in soil, freshwater, and seawater, and some bacteria are only found in seawater, such as nitrifying coccus and nitrifying stinging fungus.

Nitrifying bacteria (nitrifying) are aerobic bacteria that include nitrosifying bacteria and nitrifying bacteria. Living in aerobic water or sand plays an important role in the nitrogen cycle water purification process.

What exactly are "nitrifying bacteria" that spend a lot of money to cultivate? Explain in detail the role of raising it.

Helps the digestive system of the intestines.

Fish have two stools, including the nitride ammonia (NH3, or dissolved in water after O is NH4+), which is a highly toxic O chemical. Among the bacteria, one has a D series that feeds on ammonia, which will oxidize ammonia into nitrous acid (NO2-), and the bacteria are collectively called nitrite bacteria. Nitrous acid is poisonous, but it is not poisonous.

The other type of bacteria will turn nitrite into nitric acid (NO3-), which is called nitric acid bacteria. The strains are collectively referred to as nitrifying bacteria. As a result, there must be nitrifying bacteria in each fish tank filtration system, and if there are enough bacteria, the fish can be treated for fecal urine toxicity and the water quality is maintained.

And the D bacteria o system in nature has a friendly code bridge, do not drive to buy bacteria water have to, the important o is not only you have time to reproduce the mold with the filter material (biological ring) to settle down. Raise the bacteria o as long as the filter material is washed down with old water, do not flush directly with the water hose or wash it with life, and do not drop the medicine to avoid sterilization.

Nitrifying bacteria are used to eliminate toxins from water, and nitrifying bacteria can generally be purchased at fish shops. But you can also make your own, when the tank is opened, you can make enough gas and put a small amount of cheap fish in the tank to let it fend for itself, and after two weeks, the water quality will be stable and you can drop your favorite fish; However, remember not to change more than one-third of the water, do not clean all the filter media at once when cleaning the filter media, and do not clean the biological ring too dry, because the biological ring is the place where nitrifying bacteria live.

Digestive bacteria are toxins produced by eating fish excrement in the water. Non-digestible dwarf will poison itself. So digestive bacteria are necessary. You'll be able to get out of the way. So don't talk about it for long. So a pack to tell. If you want to raise fish, you must raise water.

Raising water means nurturing bacteria. If there are enough strains, you can raise D fish. Please do not add tap water to the bacteria that have been raised for a long time.

There is fate. It will kill the digestive bacteria.

Nitrospira is a group of gram-negative bacteria. The genus Nitrospira acts as a nitrifier that oxidizes nitrite to nitrate. Reference.

1. The role of nitrifying bacteria.

1. Decompose organic matter, this heavy manual labor is not something that can be done by delicate nitrifying bacteria, it is done by other water purification bacteria.

1) In the aquatic ecological circulation system, if there are no other heterogeneous bacteria, the water will be full of organic matter that has not been decomposed by bacteria, and this self-polluting aquarium environment will also make it impossible for fish to live in it. As a result, they are often seen as the vanguard of water self-purification, and their importance is no less than that of nitrifying bacteria.

2) This kind of bacteria is common in a variety of different environments, they are almost ubiquitous, and the reproduction rate is quite amazing, most of the heterogeneous water purification bacteria, in the ideal environment only takes dozens of seconds to multiply by themselves, generally only 20 minutes to multiply double. But if you keep it in a bare tank, you have to use physical circulation to suck out the bait or manure in the water.

2. On the issue of purifying water quality and neutralizing suspended solids in water.

1) Photosynthetic bacteria can survive in a certain polluted environment and play an important role in purifying water quality. However, it will only play its role when the living environment and polluting substances conform to their physiological and ecological characteristics, otherwise it is difficult to obtain expectations. For example, in a dark-free or aerobic environment, it is difficult for photosynthetic bacteria to be effective.

2) If there are photosynthetic bacteria in the aquarium, it will absorb and utilize those organic matter or hydrogen sulfide and other substances, so that the oxygen-consuming heterogeneous microorganisms become weak due to lack of nutrition, thus reducing the chance of toxic decomposition products, and at the same time, the water quality in the substrate can be purified, and promote the healthy growth of aquarium organisms.
