Microalgae cultures using sealed vertical photobioreactors

An apparatus for cultivation of microalgae in a culture broth, comprising:

• a device for culture broth sterilization using a micro bubble generator;
• an air compression and pressure equalization device for injection of carbon dioxide and oxygen from atmosphere into a culture broth;
• an air chilling device to maintain suitable culture broth temperature;
• an automatic carbon dioxide supply device to promote photosynthesis;
• a sealed vertical photobioreactor configured to contain a culture medium inoculated with a microalgae;
• a harvesting device comprising hollow fiber membranes;
• and
• a hot air drying device.
