Degradation activities in RHA1 cells during different growth phasesa
Substrate | Degradation activity, 10−3 μmol/min/mg (SD) |
|||
---|---|---|---|---|
ML | T83 | S88 | S150 | |
Phthalate | 0.23 (0.10) | 0.58 (0.05) | 0.26 (0.004) | 0.36 (0.007) |
Biphenyl | 0.33 (0.12) | ND | 0.15 (0.10) | 1.37 (0.07) |
The assays were performed in duplicate. The degradation activities were measured by monitoring the concentration of the substrates. ND, not detected.
