Biodegradation Of Synthetic Compounds By The Microorganisms Isolated From Different Regeions Of Telangana

Abstract

The extensive use of synthetic compounds, including pesticides, has raised concerns about their environmental impact and potential risks to human health. Microbial biodegradation has emerged as a promising eco-friendly approach to mitigate the accumulation of these compounds in the environment. In this study, we investigated the biodegradation potential of found microorganisms isolated from pesticidetreated soils in different regions of Telangana State. 50 Soil samples were collected from agricultural areas in diverse regions, known for their significant pesticide usage. Enrichment cultures were prepared using these soil samples to isolate predominantly found 10 bacterial and 5 fungal genus capable of utilizing synthetic compounds as a carbon and energy source. The isolated microbial strains were characterized by morphological, physiological, and biochemical characteristics. Subsequently, the biodegradation potential of the isolated microorganisms was assessed through laboratory-scale degradation experiments. Commonly used pesticides were selected as model substrates for degradation studies. The degradation efficiency of the microorganisms was evaluated at different incubation periods (05, 10 and 15 days) to understand their ability to break down these synthetic compounds. The results demonstrated that the degradation of pesticides by bacteria and fungi was found significant after 15th day of incubation. The degradation of tested pesticides was initiated from the 5th day. At the end of 10th day there is an exponential degradation percentage. By 15th day the degradation percentage was approximately 1fold compared to 10th day degradation percentage. This investigation emphasizes the significance of harnessing the potential of bacteria and fungi to mitigate the environmental burden of synthetic compounds. The findings hold practical implications for developing eco-friendly and region-specific bioremediation strategies to combat pollution caused by synthetic compounds and promote environmental sustainability in the agricultural sector
