Experimental Samples on on X-axis:  [G: 3 μg/L Atrazine] – [P: 10 μg/L Atrazine] - [O: 30 μg/L Atrazine] – [B: 0 μg/L Atrazine] – [A: 30 μg/L Acetone].  Colors represent a bacterial genus and the length of the color blocks indicates the proportion of the relative abundance of the taxonomy; Y-axis: Relative abundance (%).
