Morphological characteristics and identification of bacterial isolates from rhizosphere of potato, based on 16S rRNA gene sequence analysis.
| Isolate code | Isolation site | Colony morphology | Cell morphology | Gram’s reaction | ARA (nmoles mg−1 protein h−1) | Closest GenBank match of 16S rRNA with % | GenBank accession number |
|---|---|---|---|---|---|---|---|
| TN37 | Sahiwal | Medium, round, pale yellow | Short rods | −ve | 135.07 ± 8.97 | Brevundimonas naejangsanensis strain HWG-A15(99%) | LN833470 |
| TN39 | Sahiwal | Medium, round, creamy | Short rods | −ve | 127.56 ± 11.63 | Brevundimonas terrae strain KSL-145 (99%) | LN833471 |
| TN40 | Sahiwal | Medium, round, white | Short rods | −ve | 0 | Brevundimonas sp. X60 (99%) | LN833472 |
| TN44 | Sahiwal | Medium, irregular, grayish | Short rods | −ve | 93.36 ± 6.38 | Brevundimonas sp. MM68May (99%) | LN833475 |
Values are means of three independent replicates ± SE.
ARA, acetylene reduction assay.
