"The average fluorescence intensity for each spot was calculated and local background was subtracted. All data normalization and selection of fold-changed genes were performed using GeneSpringGX 7.3.1 (Agilent Technology, USA).  Normalization for Agilent one-color method was performed, which is Data transformation : Set measurements less than 5.0 to 5.0 and Per Chip :Normalize to 50th percentage."	"data_processing.1"

"When E. coli cells were cultivated to the exponential growth phase (OD600 = 0.5) in Riesenberg medium, 3 or 10 mM heptanoic acid was treated to BL21(DE3) and K-12 MG1655, respectively. After 3 h incubation, the E. coli cells were harvested for transcriptome analysis"	"growth_protocol_ch1.1"
