BIOREMEDIATION STRATEGIES FOR PESTICIDE-CONTAMINATED SOIL: I. MICROBIAL CONSORTIUM ISOLATION

摘要

Development of feasible bioremediation strategies for a pesticide-contaminated soil from an agricultural mix-load site was initiated utilizing both fungal and bacterial technologies. One strategy was to isolate a bacterial culture from the mix-load site soil to use as a tool for bioaugmentation of the contaminated site. Three different locations from the site were chosen for experimentation based on herbicide handling activities. A selected microbial consortium (SMC) that was able to degrade two specific herbicides, alachlor (2-chloro-2', 6'-diethyl-N-[methoxymethyl]-acetanilide; AL) and atrazine (2-chloro-4-ethylamino-6-isopropylamino-S-triazine; AT) was isolated from one of the sample locations. Considerable differences in soil parameters of the three sample locations were found that might have had an effect on the ability of the indigenous microbial populations within the soils to degrade AT and AL.
