Fig. 3From: Development and application of a transcriptional sensor for detection of heterologous acrylic acid production in E. colia Parental E. coli and cells expressing plasmid-encoded acrylic acid sensor were treated with indicated acrylic acid concentrations (3 h) and eGFP fluorescence measured by FACS. Traces for both control and treated parental E. coli cells (yellow, cyan and brown) overlap. b Response of PyHCN-eGFP sensor to indicated compounds (5 mM)Back to article page
