Production And Harvest Of Microalgae In Wastewater Raceways With Resource Recycling, Alexander Colin Roberts

Master's Theses

Microalgae can be grown on municipal wastewater media to both treat the wastewater and produce feedstock for algae biofuel production. However the reliability of treatment must be demonstrated, as well as high areal algae productivity on recycled wastewater media and efficient sedimentation harvesting. This processes was studied at pilot scale in the present research.

A pilot facility was operated with nine CO₂-supplemented raceway ponds, each with a 33-m² surface area and a 0.3-m depth, continuously from March 6, 2013 through September 24, 2014. The ponds were operated as three sets of triplicates with two sets continuously fed …

Bioplastic Production In Cyanobacteria And Consensus Degenerate Pcr Probe Design, Courtney Edward Lane

LSU Doctoral Dissertations

Cyanobacteria show much promise in reducing biodegradable thermoplastic production costs; however, most currently characterized strains are ill-equipped to do so. The result of Objective I produced a high-throughput assay designed to discover existing cyanobacterial strains and rapidly characterize them as PHA-producers or potential PHA-producers. This assay will play an instrumental role in the attainment of a novel cyanobacteria environmental isolate capable of accumulating high levels of PHA naturally. Objective II produced an open source computer program which dramatically speeds the design of similar assays for any arbitrary genetic screening purpose. The program is not limited to this implementation alone. In …
