Fig. 4From: Hybrid promoter engineering strategies in Yarrowia lipolytica: isoamyl alcohol production as a test studyFluorescence of the promoter library constructed in this study. The hrGFPO was used as a reporter gene for the promoter library constructed, and the fluorescence were detected by the BD Accuri C6 flow cytometer (BD Biosciences) using 488-nm excitation wavelength and FL1 channel. The error bars represent standard deviationBack to article page
