Abstract: | This study was conducted to test the feasibility of growing microalgae on steel plant exhaust gas, generated from the combustion of offgases from steel processing, which has a high CO content. Two field trials of batch algal biomass growth, mediated by microbubble transfer processes in an airlift loop bioreactor showed only steady growth of biomass with 100% survival rate. The gas analysis of CO uptake in the 2200L bioreactor showed a specific uptake rate of 0.1g/L/h, an average 14% of the CO available in the exhaust gas with a 23% composition of CO. This uptake led to a steady production of chlorophyll and total lipid constituency in the bioreactor, and an accelerating exponential growth rate of biomass, with a top doubling time of 1.8days. The gas analysis also showed anti-correlation of CO uptake and O production, which along with the apparent stripping of the O to the equilibrium level by the microbubbles, strongly suggests that the bioreactor is not mass transfer limited, nor O inhibited. Removing O inhibition results in high growth rates and high density of biomass. © 2011 Elsevier Ltd. |
