Comparison of C23DO gene copy numbers and plate counts for Pseudomonas sp. strain PpG7
| Parameter | Avg | SD |
|---|---|---|
| Clean soil extracta | 9.56 × 107 | 7.08 × 107 |
| Toluene-spiked soil extracta | 3.54 × 108 | 1.97 × 108 |
| Pure-culture extracta | 3.26 × 108 | 2.26 × 108 |
| Pure-culture plate countb | 1.41 × 107 | 1.62 × 106 |
a
Competitive quantitative PCR results are expressed as C23DO gene copy number g of soil−1. Approximately 1.4 × 107 Pseudomonas sp. strain PpG7 cells were seeded per g of soil.
b
Plate counts are expressed as CFU g of soil−1.
