Biofuel Production Coupled to Bioremediation of Industrial Flue Gas
In collaboration with Jennifer Stewart (PI), we will optimize the growth of Heterosigma akashiwo for bioremediation of dairy waste and industrial emissions (flue gas) for production of biodeisel fuel.
Industrial flue gas emissions contain high concentrations of carbon dioxide (CO2) and
the toxic gas, nitric oxide (NO). The high concentration of NO in
flue gas inhibits the growth of most microalgae and previous
attempts to utilize biodiesel-producing strains of microalgae for
bioremediation of industrial emissions containing NO have been
largely unsuccessful. Microalgae can also be used for bioremediation of
dairy waste, which contains high amounts of phosphates and other
nutrients required for algal growth. Dairy waste, however, does not
contain a high enough proportion of nitrogen to achieve maximum growth
rates by most algal species, and must be supplemented with additional
nitrogen. Research by Stewart and Coyne at UD shows that the
unicellular alga, Heterosigma akashiwo,
is capable of growth on gases containing high concentrations NO, and
can use NO as a nitrogen source. This project will investigate the
capacity of H. akashiwo for bioremediation of dairy waste and industrial flue gas containing CO2 and NO, while optimizing growth for biofuel production.
