Figure 5. Cell growth of S. avermitilis during 11-day culture and avermectin productivity of S. avermitilis during 9-day fermentation.

Figure 5

(a) Cell growth of S. avermitilis without (control) and with nsPEFs treatment in soluble FM-II during 11-day culture. Values are the mean ± standard deviation of three independent biological replicate experiments (n = 3). Statistical significance of differences between nsPEFs-treated and control cells is indicated with *when P < 0.05, **when P < 0.01. (b) Overall avermectin production of S. avermitilis without (control) and with nsPEFs treatment cultured in fermentation medium for 9 days. Vertical bars represent the mean ± standard deviation of three independent biological replicate experiments (n = 3). Bars labeled with different lowercase letters within the same fermentation day indicate a significant difference (P ≤ 0.05) and different uppercase letters within the same treatment indicate a significant difference (P ≤ 0.05). (c) The standard curve of avermectins.
