Chlorella is a kind of single-celled algae, chlorophyta, algae objective, green has found this genus. Single or crowded, the cells are spherical, elliptic, their cell walls are usually very thin, asexual reproduction, and when the new spore mother cell rupture when mature, spore escape, then grew up into a new individual. Chlorella protein content more than 50%, is rich in fat, sugar, trace elements and vitamins, chlorella contained some growth factors (CGF), can promote the growth of the children especially body and system enhancement, and can strengthen the immune system function. Since the childhood has found intracellular extract chlorophyll, astaxanthin, lutein and carotene high nutrition, can be used as high biological activity of drugs in enhancing human health as well as resistance to a variety of diseases such as cancer. 1, chlorella is can make acid constitution only weakly alkaline substances. 2, because the chlorella can make cells engulf bacteria or viruses of the network system function too lively, therefore, to strengthen the foreign invasion of bacteria and virus resistance, which can prevent disease caused by a cold or a virus. 3, chlorella has detoxification, this is because the composition of chlorella extract (CGF) S - nuclear zebina glycine to restore our red blood cells. 4, to reduce the cholesterol in the blood, promoting hematopoiesis, effective for anemia, etc. 5, make fat metabolism of normalization. 6, chlorella photosynthesis ability is dozens of times of other plants, which is the ability to absorb solar energy, especially as a result, can increase energy, eliminate fatigue, to activation of brain cells, promoting the human intelligence potential into full play have special effect. Chlorella except for human health, still can be directly as the bait fish fry shrimp and a variety of rare economy, but also has to remove ammonia nitrogen and nitrite nitrogen pollution in water, can in time to remove the heavy metals in the water at the same time, in wastewater treatment and guarantee the stability of aquatic ecosystem balance and can play a role.
