Effect of PYRQ concentration on the mineralization of BaP by strains P15 and R1a
| PYRQ added (μM) | % of added dpm as CO2 after 48 h in strain
|
|
|---|---|---|
| P15 | R1 | |
| None | 52 ± 2.1 | 25 ± 1.8 |
| 0.16 | 45 ± 1.4 | 3.7 ± 0.1 |
| 0.8 | 19 ± 2.6 | 1.2 ± 0.1 |
| 1.6 | 8.0 ± 1.7 | 1.0 ± 0.1 |
| Uninoculated control (1.6 μM) | 0.4 ± 0.2 | 0.1 ± 0.1 |

Data are means and standard deviations of triplicate measurements. Total recoveries of 14C ranged from 83 to 90% for strain P15 and from 88 to 98% for strain R1. Total recoveries in the uninoculated controls were 93 and 98%, respectively.
