Environmental toxicity of the major acidic pollutants in the flue gas mixtures has long been well known. This study addresses of using Synechococcus sp. and Chlorella sp. as effective biomaterials in their tolerance to SO2and NO2and improving their growth and survival by addition of triacontanol (TRIA) and sodium bicarbonate (NaHCO3) to the culture medium. The cultures were exposed to SO2or NO2for 10′, 15′, and 20′ periods at the 10th day of incubation. Optimum pH was found as 7.5 for Synechococcus sp. and 8.5 for Chlorella sp. at 10′ exposure to SO2or NO2gas. Toleration of both microalgal cultures towards NO2was better than SO2. Chlorella sp. had much more tolerance to acidic pollutants than Synechococcus sp. Chlorophyll a concentration of Synechococcus sp. was 0.142 μg/mL at 15′ exposure to SO2, 0.130 μg/mL at 20′ exposure to SO2, 0.296 μg/mL at 15′ exposure to NO2, and 0.142 μg/mL at 20′ exposure to NO2. Chlorophyll (a + b) concentration of Chlorella sp. was 0.667 μg/mL at 15′ exposure to SO2, 0.493 μg/mL at 20′ exposure to SO2, 0.800 μg/mL at 15′ exposure to NO2, and 0.510 μg/mL at 20′ exposure to NO2. This study highlights the potential of using Synechococcus sp. and Chlorella sp. in tolerance to NO2and SO2from flue gas mixtures at least. © 2012 Elsevier Ltd. All rights reserved.
