From: A fast method to evaluate in a combinatorial manner the synergistic effect of different biostimulants for promoting growth or tolerance against abiotic stress

Fig. 5

The semi-logarithmic plots of quaternary combinations on the continuous growth of S. cerevisiae under A control conditions (YPD without stress), and abiotic stress conditions: B NaCl 0.8 M, C LiCl 0.15 M, and D Sorbitol 1.8 M. Different concentrations of natural products were tested to obtain the optimal concentration for the combination of four compounds: 400, 200, 100 and 50 µg/ml of each compound. Growth monitoring was performed by automatic recording of OD600 every 30 min. The X-axis represents time in minutes (min) and the Y-axis represents the optical density at 600 nm (OD 600 nm) on logarithmic scale. Each point shows the mean of three replicates, with a standard error < 5% in most cases (error bars not shown for clarity)
