What are Spirulina cultivation systems?”
There is only one system called “an open-spaced pond” being used to cultivate Spirulina for commercial now. However, another system, “a close-spaced”, still exists but is not very popular because it can only be done in the laboratory, which involves temperature, light and pH controls. A glass tube is used to cultivate this GD-1 spore to make it less contaminates.
