The Effects Of Differing Light Wavelengths And Gravity On, Reese Chesshir May 2023

The Effects Of Differing Light Wavelengths And Gravity On, Reese Chesshir

Honors Theses

Physarum is a slime mold in the class of Mycetozoan and the family of Physaraceae. It is a single cellular, multinuclear organism that is not classified as an animal, plant, or fungi. Physarum growth for long-term space travel would be beneficial because it is a decomposer and is able to break down material and waste to recycle. This is important for transferring energy and allowing other organisms to grow. The purpose of this experiment is to study the effect of different light wavelengths and the influence of gravity on Physarum growth patterns.


Effects Of Red Light Intensity On Cultivation And Oxygen Production In Arthrospira Platensis, Abigail Roberts Dec 2022

Effects Of Red Light Intensity On Cultivation And Oxygen Production In Arthrospira Platensis, Abigail Roberts

Honors Theses

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/m2/s (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 …
