Microbial activities directly affect the environmental quality of water, soil, and sediments. To improve our understanding of microbial attachment and transport in the subsurface, experimental studies were performed to evaluate bacterial adsorption and transport in two types of soil, Smolan (27% clay) and Haynie (5.5% clay) soils. Results indicate that bacterial breakthrough was slightly faster in columns with lower clay content and that the most rapid rate of bacterial adsorption occurred during the first 60 min of exposure.
微生物活动直接影响水、土壤和沉积物的环境质量。为了增进我们对微生物在地下的附着和运移的理解，开展了实验研究以评估细菌在两种土壤（斯莫兰土壤（27% 黏土）和海尼土壤（5.5% 黏土））中的吸附和运移情况。结果表明，在黏土含量较低的柱体中细菌穿透略快，且细菌吸附的最快速率发生在暴露的最初60分钟内。
