Figure 1.
Cell growth (a) and pH changes (b) of the simulated kimchi juice (SKJ) after inoculation of 17 probiotic lactic acid bacteria (LAB) at their optimal growth temperatures, 37 or 30 °C. Optical density (OD600nm) values and pH values were measured for 24 h. The dotted lines represent little microbial growth (<OD 0.3) and pH changes (<pH 5.0). Results are expressed as means ± standard deviations (n = 3).
