Table 2.
The available concentration of Zn and reduction in pH of the media by rhizobacterial strains in response to zinc oxide.
| Bacterial Strains | Available Zn Concentration (ppm) | pH Reduction in Response to Zinc Oxide |
|---|---|---|
| Control | 2.16 ± 0.09 f | 6.78 ± 0.01 a |
| SM2 | 19.11 ± 0.29 bc | 5.32 ± 0.09 c |
| SM4 | NT | NT |
| SM5 | 17.96 ± 0.93 c | 5.18 ± 0.06 cd |
| SM7 | 19.81 ± 0.33 b | 4.79 ± 0.08 de |
| MS1 | 11.63 ± 0.29 e | 6.17 ± 0.4 b |
| MS2 | 15.33 ± 0.45 d | 5.01 ± 0.02 cd |
| MS4 | NT | NT |
| MS7 | 21.72 ± 0.39 a | 4.60 ± 0.08 e |
| CVC | 1.5441 | 0.2258 |
The symbol NT stands for not tested; CVC stands for critical value for comparison at p ≤ 0.05; The means sharing the same alphabet letters were non-significant from each other.
