Abstract Details

2011, Master of Science, Miami University, Microbiology.
The psychrophilic green alga, Chlorella BI sp. was isolated from a transient Antarctic pond as part of a mat consortium. Previous research on Chlorella BI sp. showed that the organism was able to utilize inorganic and organic forms of carbon and alter its photosynthetic apparatus in response to varying trophic growth states. Based on these early results, the goals of this thesis project were to: (1) characterize the photosynthetic apparatus of Chlorella BI sp. under different trophic states in comparison to the mesophilic species, Chlorella vulgaris; and, (2) determine the effect on the photosynthetic apparatus of Chlorella BI sp, when it is shifted from dark to light conditions. Chlorella BI sp. grew exponentially under the three tested trophic states. The photosynthetic apparatus exhibited functional and structural alteration. It is concluded Chlorella BI sp. has retained the ability to alter its photosynthetic apparatus in response to adaptation to a variable habitat.
