Expression analysis of RFP in Y. lipolytica and K. marxianus transformant strains. a Mean RFP fluorescence intensities (RFU) of the colonies (n = 5) of each Y. lipolytica or K. marxianus transformant strain with reporter gene RFP under control of each promoter cultured for three days are shown with standard errors (gain value 80); b Microscopic fluorescence images of the colony with the highest fluorescence value of each Y. lipolytica or K. marxianus transformant strain cultured for one day, two days, three days. Fluorescent images of the strains were taken in the same setting
