Abstract

The invention relates to a method that could cultivate algae by PH feedback control to add CO2 that belongs to tiny algae cultivating field. The PH value of culture solution is set in a certain range, and according to the difference between the practical test vale of the PH value in the culture solution and the preset value, the CO2 would be added to make the PH value be in the certain range of the preset value. It would not be finished until the condition that could stop cultivating emerges. The invention realizes automatically adding carbon and automatically controlling PH value for algae cultivation.

Description

technical field

[0001] The invention belongs to the field of microalgae cultivation, in particular to a method for cultivating microalgae by adding carbon dioxide through pH feedback control. technical background

[0002] Microalgae are rich in protein, polysaccharides, unsaturated fatty acids and other nutrients (such as spirulina), which can be used in food and medicine; contain a variety of pigments (such as Porphyridium), which can be used in cosmetics, bioengineering and medical diagnosis; A large amount of hydrocarbons are accumulated, and the hydrocarbon content can account for more than 50% of the dry weight (such as Botrytis), which can be directly used for power generation; some microalgae can fix nitrogen and can be used as natural fertilizers (such as Anabaena), controlled by nutrition It can be used as high-quality bait; some microalgae also contain antibiotics and toxins, which are of great medicinal value. Microalgae have become raw materials for food, health...
