Representative fluorescence histogram data of GFP-P17 and P17 in water.

<p>The x-axis shows green (FITC) fluorescence intensity, and the y-axis shows the number of events recorded for a corresponding fluorescence intensity. 1, water sample without cells; 2, water sample with P17; 3, water sample with GFP-P17.</p

AOC concentration measured using flow cytometry (FC) method and spread plate counting method(SPC).
