Green light-induced production of alcohol using the CcaS/CcaR system with additional expression of ccaR. a Expected scheme of gene expression regulation under the control of the CcaS/CcaR system with an additional expression of ccaR from PcpcG2 under green light illumination. Titers and specific titers of isobutanol (circle) and 3MB (square) by Synechocystis sp. PCC 6803ΔGSS transformed with pKT-GSS-KDC-ADH-CcaR, which was cultivated b, c under red and green light or d, e under red light illumination alone. All analyses were performed in triplicate. Error bars represent the standard deviation (SD) calculated from triplicate experiments using one clone
