Fig. 2From: Engineering Comamonas testosteroni for the production of 2-pyrone-4,6-dicarboxylic acid as a promising building blockMeasured activity of the promoter regions upstream of the PCA and TPA degradation operons. Activity was induced through the addition of TPA to the medium. Promoter activity was tested both in the wild-type strain (C. testosteroni KF-1) as well as the strain with a deletion of pmdD (sCT01)Back to article page
