Fig. 1From: Adaptive laboratory evolution of cadmium tolerance in Synechocystis sp. PCC 6803Experimental setup of ALE process in this study. a Increasing CdSO4 concentration was from 4.6 to 9.0 µM. Agar plate supplemented with 9.0-µM CdSO4 was then used to isolate single clone. b Simplified evolution process of Cd2+ tolerance in Synechocystis. The x axis represented passages and y axis represented the simplified Cd2+ concentration. The specific evolved concentrations of cadmium were 4.6, 5.0, 5.4, 5.8, 6.2, 6.6, 7.0, 7.3, 7.7, 8.0, 8.3, 8.6, and 9.0 µM. Three points represented three strains for sequencing in this study.
