Relative expression levels of a dhaR, b dhaL and c dhaT in KMK-23M, KMK-46 and KMY strains detected by real-time RT-PCR. The expression levels of KMK-46 and KMY were normalized with cell mass (OD600) and with the ones of control strain, KMK-23M. The expression levels were measured three times with the strains grown in 40 g L−1 glycerol and 20 g L−1 mannitol up to mid-log phase and the error bars represented the standard deviations
