- Study to find the Rhizobium strain that acid and Al tolerant was done in liquid medium in laboratory. The treatment was tested namely pH medium (4.0; 4.5; 5.0 and 5.5) and Al concentration (0.0; 0.6; 1.0; 3.5; and 10.0). The result showed that from 26 isolates was tested only 15 isolates (58%) can grow at pH 4.0 with Al concentration until 3.5 ppm. Unfortunately, there were no isolates can grow at 10.0 ppm. Based on visible turbidity (about 106 SPK.ml-1), only seven isolates (GR2 - 3, GR2 - 7, GR2 - 28, GR2 - 29, GR2 - 33, GR3 - 4 and GR3 - 17) were tolerant, while the other isolates (BR - 13, GR2 - 10, GR2 - 15, GR2 - 30, GR3 - 9, GR3 -13, GR3 - 14 and GR3 - 15) were part tolerant.
