Abstract
Atmospheric carbon dioxide levels have increased since the industrial revolution due to increasing combustion of fossil fuels. One possible CO2 mitigation strategy is the use of microalgae for mitigation of CO2. This paper focuses on the influence of media composition on the growth rate of two microalgae strains, Chlorella vulgaris and Scenedesmus actus. A KNO3 based medium was found to work better for Chlorella, while a urea based equivalent worked better for Scenedesmus. The urea based media investigated here resulted in growth similar to that found with previously reported KNO3 based media. This should result in an economic benefit in large scale algae cultivation for CO2 mitigation, as urea is typically less expensive than KNO3. Additional media components were tested and it was found that EDTA, vitamin B, and the addition of B, V, and Mo do not result in a significant increase in algae growth rate under process conditions used.
