Fig. 6From: Development of a genetically programed vanillin-sensing bacterium for high-throughput screening of lignin-degrading enzyme librariesToxicity of potential lignin degradation products and acrylic acid towards the VSC biosensor. Toxicity was tested with 0 mM (black line), 2.5 mM (red line), 5.0 mM (blue line), 10.0 mM (green line) and 20 mM (magenta line) of indicated chemicals. The biosensing cells were grown in the presence of individual chemicals and cell growth (OD600) was measured at 30-min or 1-h intervalsBack to article page
