BVC profiling in the miniature greenhouse system. Chromatographic profiles of 2,3-butanediol isomer released from B. subtilis GB03. B. subtilis GB03 grown for 3 (a) and 7 (b) but not for 14 (c) days released 2,3-butanediol (BDO) isomers. Air = negative control treatment. Significant differences are indicated by numbers defined as follows: 2(R),3(R)-BDO (peak 1) and 2(R),3(S)-BDO (peak 2). d Chromatographic profiles of the synthetic chemical standard compounds 2(R),3(R)-BDO (peak 1) and 2(R),3(S)-BDO (peak 2). Air = negative control treatment. e Concentration of 2(R),3(R)-BDO (peak 1 in a–d) and 2(R),3(S)-BDO (peak 2 in a–d) released by B. subtilis GB03. (d inset graph). Calibration curve of 2,3-BDO. Bars represent mean ± SE. Sample size was n = 4 plants per treatment. The experiment was repeated three times with similar results
