How is Porphyridium cruentum cultivated?

Porphyridium cruentum is grown in closed photobioreactors. Since this microalga is a rather rare variety in cultivation, it is accordingly valuable. Photobioreactors make it possible to keep a close eye on environmental factors and give the microalgae the best possible place to grow.

In addition, contamination is avoided more efficiently in these closed systems than in open cultivation.
