The influence of dissolved oxygen on microorganism is mainly determined by the activity and distribution of aerobic and anaerobic microorganisms. When the dissolved oxygen is enough, microbes can carry out aerobic respiration. Aerobic microorganisms can move smoothly, decompose organic matter thoroughly and produce non-toxic and harmless substances. On the contrary, if the dissolved oxygen in the water is insufficient, organisms can only use some inorganic or organic substances instead of O2 for anaerobic respiration, then only anaerobic or facultative anaerobic microorganisms can be active. They decompose organic matter relatively slowly and have low energy efficiency, producing toxic or adverse effects on fish and other food organisms.
Therefore, under different dissolved Water Oxygen Bubble Cleaning conditions, the population, quantity and distribution of microorganisms in the water body are very different. When dissolved oxygen in the water is sufficient, aerobic and facultative aerobic microorganisms not only predominate in quantity, but also relatively large species, such as Bacillus, photosynthetic bacteria, nitrogen-fixing bacteria, and so on, which are beneficial to cultured animals. At the same time, when dissolved oxygen in water is sufficient, it will inhibit the growth of anaerobic bacteria, such as Aeromonads enteric, and Escherichia coli and so on. Most of these microorganisms are harmful to cultured animals.
In his paper published in 2001, Forth and others injected water with different oxygen ratios into the rabbit’s stomach. When the dissolved oxygen amount of oxygen containing water is more than 45 mg/L, the dissolved oxygen in water can be absorbed from the stomach to the portal vein. This confirms that the stomach and intestines can absorb dissolved oxygen in water. It is expected that this phenomenon may be applied to the study of liver perfusion (liver perfusion). However, the paper did not discuss muscle fatigue or lactate value.
Drink highly oxygenated water, change the body well? In recent years, it has been preliminarily speculated that high oxygen content water is related to the effect of dealcoholation. Also found that drinking highly oxygenated water could increase the immunity of pigs to typhoid fever.
But Ishida Koji, at the Nagoya University in Japan, found that drinking highly oxygenated water did not change any physiological index in the results of a 2006 experiment on students. Fortunately, drinking such highly oxygenated water should not hurt the body. Two studies confirmed that highly oxygenated water had no significant harmful effects on human liver, blood and immune system. But it is found that drinking highly oxygenated water will increase the production of oxygen radicals in a short time, and the mechanism is still unknown.
Therefore, there is no scientific evidence for improving health with high oxygen content water.
