Effect of vitK3 on smeVWX expression. The fluorescence levels obtained by smeVWX expression when OD600 of 0.6 is reached in PBT02 strain, PBT02 strain after incubation with 1 mM vitK3, and PBT06 strain are shown. vitK3 increases YFP expression in comparison with the untreated strain, although the level reached is lower than in PBT06. Error bars indicate standard deviations of the results from three independent replicates.
