Maintaining life sustaining resources during long-term space travel has encouraged scientists to turn their attention to the potential benefits of a cyanobacteria named Arthrospira platensis, commonly known as Spirulina algae. This experiment measures the oxygen production and cell population growth of two structurally different Spirulina cultures under two different levels of red light intensities, 8 µmol/m 2Js (high); 3 µmol/m2/s (low). The cell population, oxygen produced, and oxygen produced per cell measurements were observed and recorded at three 24 hour intervals. It was found there was not a significant difference between high and low light intensities when considering the cell concentration data which indicated the red light intensities did not affect the cell concentration level. However, both the oxygen alone and oxygen per cell produced from the high and low light intensities were found to result in significant data differences.
