Abstract: The 22 isolates obtained from Acacia nodules were compared for their acid tolerance in this study. The results indicate that most of them could not grow at pH 5.0,but isolates IS002,IS004,CR002 and LR007 could grow at pH 5.0,IS002 and IS004 not only could grow at pH 3.86 but also in acid soil suspension (pH 4.9),which had high survival rate than the other strains. IS002 was selected in this study as acid-resistant strain.
