Figure 2

The algal autofluorescence intensity (A) and ROS fluorescence intensity (B) of algal cells under 5% Bacillus sp. LP-10 filtrates treatment with addition of ROS scavengers. CK represents algal cultures without any addition; LP represents algal cultures treated by 5% filtrates of Bacillus sp. LP-10; NAC represents algal cultures with addition of NAC; NAC + LP represents algal cultures with addition of NAC treated by 5% filtrates of Bacillus sp. LP-10. GSH and AsA are similar with those.
