Fig. 5From: Hybrid phenolic-inducible promoters towards construction of self-inducible systems for microbial lignin valorizationFlow cytometric analysis of vanillin-induced cultures. E. coli strains RIF01, RIF02, RIF03, and RIF04 contained promoters PemrR, Pvtac, Pvtrc, and Pvtic, respectively, for the expression of mcherry. Fluorescence (FL) was used as a measure of promoter strength, and forward scattering (FSC) was used as a measure of cell sizeBack to article page
