| BNF | Phosphate solubilization (μg mL-1) | IAA (μg mL-1) | Siderophore Production | ACC deaminase | Proteases (mm) | Cellulase activity (mm) | Ligninolytic activity | |
| A20 | UD | 79.53 ± 7.43a | 4.07 ± 1.83a | + | UD | 12 ± 1.64 | UD | UD |

Each assay was done three times with three biological replicates, and values represent their means ± standard deviation. One way-ANOVA (p < 0.05) was used to compare means. Values sharing a letter, within a column are not statistically different. UD, Undetectable activity. BNF, Biological Nitrogen Fixation. IAA, Indoleacetic Acid Production.
