Effects of ethanol, butanol, hexane, salt, and nitrogen starvation on growth of Synechocystis. Growth curves of wild-type Synechocystis in BG11 medium control (WT), medium with biofuel at the indicated concentration (v/v), medium with 4% NaCl (w/v), or BG11 medium without nitrogen sources (N starvation). Error bars represent the calculated standard deviation of the measurements of three biological replicates
