- * The doubling time of the SL7207 strain was significantly different from those of the six single-recombinant strains (p < 0.05); ** The doubling time of the CO strain was significantly increased compared to those of the other five single-recombinant strains (p < 0.01); (a) A significant difference was observed between the doubling times of the LP strain and the strain containing the corresponding empty vector ACYC177 (p < 0.01); (b) The doubling times of the HO and OmpA strains are significantly different (p < 0.05).
