Levels of c-di-GMP vary in response to the aeration conditions of the culture medium. (A) Determination of the molecular mass of the alginates produced by the AEIV strain (WT) and the ΔmucG mutant at the indicated OTR. (B) Quantification of c-di-GMP in the same strains as in panel A. The cells were cultivated in Burk’s-sucrose medium for 48 h. Means and standard deviations from three independent experiments are shown. Statistical analysis of c-di-GMP changes under the different OTRmax conditions evaluated is presented in Fig. S3.
