Effect of polyP₆ concentration on ε-PL production by strain PL05 in batch‒fermentation. A: ε-PL production. B: Biomass. C: Intracellular ATP content. D: Intracellular ADP content. The data are presented as averages, and the error bars represent standard deviations (n = 3 independent experiments). ^* 0.01 < P < 0.05, ^** P < 0.01, ^*** P < 0.001
