Changes in the transcription levels of genes related to glycolysis, gluconeogenesis, and glycerol metabolism pathways in Enterobacter sp. FY-07 when the carbon source was changed from glucose to glycerol. Red arrows indicate that the expression of genes encoding the enzymes related to this reaction was upregulated; green arrows indicate downregulation under the same conditions; A red square indicates the transcription level of the coding gene upregulated one fold; A green square indicates the transcription level of the coding gene downregulated one fold; An orange square indicates the transcription level of the coding gene upregulated 50 folds. Exact numerical results of relative fold changes were shown in Additional file 1: Figure S1.
