Description
Arthrospira plantensis (spirulina) is a photosynthetic alga known for its health benefits. The goal was to determine the most effective light intensity for oxygen production and overall health of the algae. Samples of mixed spiral and straight spirulina and mostly spiral spirulina were grown under three different light intensities, and trends in oxygen production and cell counts were observed over 120 hours. Generally, there were peaks in oxygen production and cell counts 48 and 96 hours after start of the experiments, and dips in oxygen production and cell counts after 72 hours. While the spiral variety had the highest oxygen production after 24 hours, and the mixed variety under the control light had the highest oxygen production after 48 hours, the oxygen production across all treatments after 120 hours was similar. There was not a light intensity that resulted in significantly higher oxygen levels or cell production.
