Alka(e)ne production in Synechocystis mutants overexpressing two copies of alkane biosynthetic genes. (A) Alka(e)ne production in the Synechocystis mutant overexpressing sll0208 and sll0209 in both slr0168 and ddh gene sites (LX56) compared with wildtype strain (6803yu) and the Synechocystis mutant overexpressing two copies of sll0208 and sll0209 in slr0168 site (LX70). Error bars represent the standard deviation of three replicates. (B) Growth curves of wildtype strain and the LX56 strain in the bubble column photo-bioreactors. Error bars represent the standard deviation of three replicates. (C) Alka(e)ne production calculated as a percentage of DW of LX56 strain was enhanced by 8 times compared with wildtype strain when cultivated in the bubble column photo-bioreactors. Error bars represent the standard deviation of three replicates.
