Fig. 6From: Overexpression of bicarbonate transporters in the marine cyanobacterium Synechococcus sp. PCC 7002 increases growth rate and glycogen accumulationMeasurement of the extracellular carbohydrate in the culture medium. Extracellular carbohydrate measured in the culture medium of the wild type (WT), SbtA-overexpressing (A) and BicA-overexpressing (B) strains was measured after 5 days of growth with bubbling of air, 1% CO2 or 3% CO2. * represents a statistically significant difference from the wild-type cells grown under similar CO2 level, n = 3Back to article page
