Analysis of antioxidant potential of algal cells. a Cellular ROS content as determined by H2DCFDA assay under 70% hyposaline condition for 4- or 7-day treatment. b Enzymatic assay of POD under 70% hyposaline condition for 4- or 7-day treatment. c Enzymatic assay of SOD under 70% hyposaline condition for 4- or 7-day treatment. d Cellular ROS content as determined by H2DCFDA assay under 70% hyposaline condition for 4- or 7-day treatment. e Cellular ROS content as determined by H2DCFDA assay at chilling condition (10 ºC) for 4- or 7-day treatment. f Enzymatic assay of POD at chilling condition (10 ºC) for 4- or 7-day treatment. g Enzymatic assay of SOD at chilling condition (10ºC) for 4- or 7-day treatment. h Cellular ROS content as determined by H2DCFDA assay at chilling condition (10 ºC) for 4- or 7-day treatment. Significant difference is indicated at the p < 0.05 (*) or p < 0.01 (**) level. Each value represents the mean ± SD (n = 3)
