The Effects Of Light Intensity On Cell Population And Oxygen Production Of Arthrospira Platensis, Sophia Ward, Cole Turner
Scholars Day Conference
As space exploration becomes more advanced, scientists look to find new ways to create nourishment and oxygen to maintain long-term space travel. Arthrospira platensis, commonly known as Spirulina, could be a possible solution to these problems. This cyanobacterium converts carbon dioxide into pure oxygen and the cell structure (coiled or straight) appears to trigger different oxygen and cultivation responses. Mixed (coiled and straight, Fig. 4) and coiled (Fig. 5) Spirulina cultures were transferred into 2.5 L containers and placed in white light boxes with varying intensities of light: 15 µmol/㎡/s, 7 µmol/㎡/s, and 3 µmol/㎡/s. Each experiment lasted 72 hours …
