Figure 3From: Development of a fluorescence-based method for monitoring glucose catabolism and its potential use in a biomass hydrolysis assayResponse to the addition of glucose. E. coli strains crp*-gfp and crp*-gfp- grown in modified 1 × M9 minimal media containing 2% glucose for 20 h. 8% glucose was added after 20 h to the indicated cultures. (a) Each time point is the average absorbance of three replications. (b) Each time point is the average fluorescence of three replications of crp*-gfp cultures minus the average fluorescence of three replications of crp*-gfp- cultures. All points are the mean ± s.e.Back to article page
