摘要
对２２株相思根瘤菌耐酸性的比较结果得出：大多数的相思根瘤菌不耐酸。在ｐＨ５．０条件下大多数根瘤菌生长不好，只有ＩＳ００４、ＩＳ００２、ＣＲ００２和ＬＲ００７菌株生长较好，在培养基ｐＨ３．８６条件下和在ｐＨ４．９土壤悬液中，ＩＳ００４和ＩＳ００２菌株的生长及存活率较其它菌株高，通过在酸性条件下生长与结瘤的试验，初步筛选出耐酸菌株ＩＳ００２。
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.
