Probiotics are a kind of active microorganisms that are beneficial to the host by changing the flora composition of a certain part of the host through colonization in the human body. By regulating the immune function of the host mucosa and system or by regulating the balance of intestinal flora, nutrient absorption can be promoted and intestinal health can be maintained, thus producing a single microorganism or mixed microorganism with clear composition beneficial to health.

Probiotics participate in various circulation processes in water, consume organic matter in water through their own metabolism, and reduce the concentration of nitrite nitrogen and ammonia nitrogen in water, thus achieving the effect of improving and maintaining good water quality.

Oxides in the body, such as oxygen free radicals and hydroxyl free radicals, contain unpaired electrons, which are prone to redox reactions. When there are too many oxides in the body, it will lead to oxidative damage to the body. There is an antioxidant system in the body, which constantly removes the oxides synthesized by the body and maintains the dynamic balance of oxides.
