Abstract

The effects of polychlorinated biphenyl (PCB) and phenanthrene stress on glucose uptake by natural microbial populations were examined by the heterotrophic potential technique. Temporal and spatial distributions in glucose uptake velocities were examined for natural samples as well as PCB- and phenanthrene-stressed samples. Statistical analysis indicated significant variability among the various samples. It was demonstrated that the environmental variables contributed significantly to the variability in uptake kinetics. Although general trends indicated a PCB-induced stimulation in uptake velocities, these trends were in part masked by sample variability. Data analysis indicated no statistically significant PCB or phenanthrene effect on either total glucose uptake velocities or the proportion of 14CO2 evolved, as compared to natural unstressed samples.

摘要

采用异养潜力技术研究了多氯联苯(PCB)和菲胁迫对天然微生物群落葡萄糖摄取的影响。对天然样品以及受PCB和菲胁迫的样品的葡萄糖摄取速度的时空分布进行了研究。统计分析表明,不同样品之间存在显著差异。结果表明,环境变量对摄取动力学的差异有显著影响。尽管总体趋势表明PCB会刺激摄取速度,但这些趋势部分被样品变异性所掩盖。数据分析表明,与未受胁迫的天然样品相比,PCB或菲对总葡萄糖摄取速度或14CO2释放比例均无统计学上的显著影响。
