Figure 6From: Gene encoding γ-carbonic anhydrase is cotranscribed with argC and induced in response to stationary phase and high CO2 in Azospirillum brasilense Sp727 Effect of growth phase and CO 2 concentration on argC - gca1 promoter activity β-galactosidase assay was performed with A. brasilense Sp7 cells harbouring either pRKK200 (empty vector) or pSK8 and grown up to either exponential or stationary phase at ambient air, and exponential growing cells at high CO 2 concentration. The assay was performed on two different occasions. The error bars indicate standard deviation from the three replicates.Back to article page
