Table 2 The deaminase activity of 1-aminocyclopropane-1-carboxylate (ACC) and the indole-3-acetic acid (IAA) concentrations in different strains of Kosakonia sp. S1 (S1), Enterobacter sp. E5 (E5), Klebsiella sp. Kb (Kb), and the engineered strains of E5, S1, and Kb (designated as E5P, S1P, and KbP, respectively) by expressing deaminase on the bacterial cells
