Development Of Phagotrophic Algae-Based Process For Conversion Of Waste Organics To Algae Lipids As Potential Feedstock For Biofuel, Hannah Nelson

Williams Honors College, Honors Research Projects

Interest in sustainable feedstock for biofuel has encouraged research on the production of phagotrophic algae from bacteria using a two-staged continuous-flow system. Bacteria cultures were fed the content of a waste stream from The J.M. Smuckers Company containing high concentrations of sugar. In the design, the bacteria effluent overflowed into the algae tank which was kept at a set volume. Several methods were developed to assist in maintaining the system at steady state and minimize the impact from contaminants. A rigorous cleaning protocol was implemented for both tanks, effectively eliminating protozoa from the bacteria system. The protozoa were decreased in …
