(674f) Investigation of Chlorella Microalgae Cultivation On Anaerobically Digested Manure Conference: AIChE Annual MeetingYear: 2010Proceeding: 2010 AIChE Annual MeetingGroup: Sustainable Engineering ForumSession: Advances in Algal Biorefineries I Time: Thursday, November 11, 2010 - 5:20pm-5:45pm Authors: Bassi, A. S., The University of Western Ontario Chandok, G., The University of Western Ontario Razzak, S., The University of Western Ontario Schnurr, P., The University of Western Ontario Laboratory and pilot scale studies were carried out to investigate the cultivation of the microalgae Chlorella vulgaris on anaerobically digested manure from a local farm. The effects of light, nutrient load and CO2 to air ratios on cell growth and lipid accumulation were investigated. Both batch and continuous studies were carried out. Rates of CO2 sequestration were also measured. The results showed that the photo-bioreactor configuration was appropriate to cultivate microalgae on a large on farm operation. Only a small fraction of CO2 supplied was effectively taken up as microalgae biomass, indicating that using microalgae only for CO2 uptake is not effective.
