Effects Of Temperature And Nitrogen Depletion On Biodiesel Production Under Saline Conditions By A Mixed Algal Community, Sarah J. Kintner

Nanoscience and Microsystems ETDs

The overall objective addressed in this research was to gain a better understanding of how native mixed cultures of phototrophic microorganisms from a saline system may be used for biodiesel production. Laboratory batch reactors were grown under variable temperatures and nitrogen concentrations with original inoculum from a hypersaline pond in central New Mexico. Growth at 40 C° led to lower lipid production, lower nitrate consumption, and less diverse communities than growth at 20° C. All communities were dominated by the cyanobacteria Plectonema except the in second experiment, where they were only 30% of the culture. In a second experiment with …
