Fluorescence intensities of the mutant library, which consisted of a pool of phaC genes with PCR-introduced random mutations. Every single mutant clone was inoculated in a 96-deep well plate and cultivated for 20 h in 800 µl of LB medium with 20 g/L glucose. Fluorescence intensities were monitored after transferring 100 µl of culture solution into a black microplate. The x axis represents the names of the mutants.
