Cellular toxicity of S. elongatus PCC 7942 with different solvents for in situ extraction. Growth (OD730) of the wild type was measured with different solvents. 20 % (v/v) of the solvent was added into the culture medium at 1 day (indicated in red arrow): no solvent overlay (black square), dodecane (red circle), hexadecane (orange triangle), and tetradecane (blue inverted triangle). All data are the mean ± standard deviation (SD) from the duplicated cultures
