The relative transcriptional levels of several randomly-selected genes during levoglucosan utilization relative to fructose utilization. E. coli LGE2 cells were cultured at 37 °C and 150 rpm in levoglucosan- and fructose-based M9 minimal media, and then harvested at both the early- and mid-log phases. A The upregulated mRNAs. B The downregulated mRNAs. The light grey column denotes the mRNA was sampled at early-log phase, while the dark grey column denotes that at mid-log phase
