Effect of NaCl concentration on the growth rates of the strains isolated from common bean nodules. R. gallicum 8a3 (■) was grown in M79-I with 20 mM glucosa. R. etli 12a3 (□) and R. leguminosarum 31c3 (▲) were grown in M79-I with 20 mM mannitol, and R. tropici CIAT 899 (control) (Δ) and A. tumefaciens 10c2 (●) were grown in MAS with 20 mM mannitol. Growth rates are expressed as ΔOD600/h. Values shown are the mean of two replicas of each condition in three independent experiments ± SD (standard deviation).
