Transport of atrazine-degrading genetically engineered microorgnism in real soil under saturated flow condition
Bacterial transport through porous media is an important process in both natural and engineered systems. One of the important applications is enhancement of in situ biodegradation through injection of specialized bacteria and the efficient bacteria delivery to targeted locations is the key for this strategy. The influencing factors for bacteria movement in the porous media, quartz sand bed or other artificial granule bed mainly, have been reported in the past research cases, including the properties of porous media, solution chemistry and characteristics of bacteria. The transport of an atrazine-degrading genetically engineered microorganism (GEM) in real cultivation and forest soil under saturated flow condition was investigated in this work. The effects of soil properties on pore-water flow and bacteria transport were examined to benefit the future application of GEM for atrazine bioremediation in soil and corresponding ecological safety assessment.
