Figure 1From: Increased biomass production and glycogen accumulation in apcE gene deleted Synechocystis sp. PCC 6803Confirmation of complete deletion of the apcE gene. (a) PCR with primers flanking the apcE gene for ΔapcE mutant (Lane 2) and glucose-tolerant Synechocystis sp. PCC 6803 (GT) (Lane 3). Lane 1 is DNA size marker (M). (b) Absorption spectral analysis of GT (black line) and ΔapcE (grey line).Back to article page
