Fig. 2From: Cell-growth phase-dependent promoter replacement approach for improved poly(lactate-co-3-hydroxybutyrate) production in Escherichia coliP(LA-co-3HB) production and expression levels of phaC1STQK-AB operon over the course of cultivation time by E. coli harboring pTV118NpctphaC1ps(ST/QK)AB in glucose-supplemented LB medium. A The bars indicate the amount of 3HB units in the polymer (black), the amount of LA units in the polymer (white), and the fluorescent intensities of Nile-red-stained cells (gray). B Diagonal stripe bars indicate the mRNA levels of phaC. The line graph shows cell growthBack to article page
