Biodegradation Of Propanil by Fusarum Oxysparum from Rice Farm

Propanil is a widely used aniline contact herbicide. It has been reported that poor handling and application of propanil have adverse effects on non -target organisms and can cause water pollution through runoff, persistence of propanil and its by–by-products, human health problems, and reduced crop yields Propanil is a widely used aniline contact herbicide. It has been reported that poor handling and application of propanil have adverse effects on non-target organisms. It can cause water pollution through runoff, persistence of propanil and its by–products, human health problems, and reduced crop yields. The propanil degraders were further characterized with molecular typing using 16s rRNA sequencing. The biodegradation study was conducted for fourteen days and the residual concentration of propanil was determined using gas chromatography. The microbial examination of contaminated propanil soil showed the presence of Fusarium sp and a preliminary test showed Fusarium oxysporum. The study showed that the application of propanil to agricultural fields is safe as there are indigenous microorganisms that can degrade it and the consumption of rice grown on propanil-contaminated soil will not be hazardous to human health as the residual propanil concentration is much below the level stipulated by regulatory authorities
