Bioremediation Potential Of Plant-Bacterial Consortia For Malathion Removal Using Constructed Wetlands

Abstract

Malathion is a toxic material, and we want to see the effect of different bacterial consortia and their biodegradation potential in the process of achieving maximum degradation of Malathion. The study first defines the parameters of the soil without the bacterial consortia and plants then after treatment with the bacterial consortia and plants provides useful insights regarding their ability to degrade Malathion effectively. To achieve the objectives, we constructed wastelands taking soil from the target areas. Then each wasteland was introduced with a progressively increasing dose of Malathion from 50 to 200 ml. It is also effective in understanding the relationship between the concentration of Malathion and the biodegrading effect of bacterial consortia and plants. Two Bacterial consortia have been found to be highly effective in Malathion biodegradation, additionally, these have been found to act rapidly and effectively. Another consortia was found to be more effective in high Malathion concentrations than lower concentrations. One consortium in particular was not very effective at the start but with time started to show biodegradation potential and achieved 99.8% biodegradation efficiency for Malathion. Plants were seen to be slower in biodegrading Malathion but still are effective up to 99.8% efficiency. The measuring technique used is the colorimetric method by which the amount of Malathion was estimated. The study proves to be an important breakthrough towards a green future. All the aforementioned processes and results have been discussed below with a detailed overview of the related literature.
