Abstract
A bacterial species having the ability to grow in t he presence of carbosulfan pesticide “Marshall” was isolated from Solanum melongena (brinjal) cultivated soil in Khulna region, Bangla deh, having a history of pesticide usage. The strain was morpholo gically and biochemically identified to belong to the genera Pseudomonas . A comparative study of growth of this strain with other isolated bacteria showed its ability to grow in the presence of diffe rent concentrations of Marshall. The susceptibility of the stain to Marshall was also assessed through dis k diffusion assay which showed the strain to be resistant at concentrations of Marshal commonly use d under field conditions. The selected strain also showed its capability to degrade Marshall through o bserved characteristics on sublimated agar plates. The biodegradation capability of the strain isolate d in this study can be valuable for further study towards bioremediation of pesticide contaminated so ils.
Highlights
In soil may directly and indirectly affect soil enzyme activities and physiological characteristics of Bangladesh is an agricultural country
Three morphologically different colonies of bacteria were selected from EMB agar plates containing pesticide
The bacterial strains were Termed as test Organism 1 (TO1), Test Organism 2 (TO2) and Test Organism 3 (TO3)
Summary
In soil may directly and indirectly affect soil enzyme activities and physiological characteristics of Bangladesh is an agricultural country. The use of remains the most efficient and cost-effective option to pesticides is considered beneficial in augmenting crop clean up pesticide-contaminated sites Such types of yields, excessive and indiscriminate use can lead to microorganisms generally have diverse ability to act microbial imbalance, environmental pollution and upon the pesticides including their ability to degrade health hazards Carbamate pesticides have been used extensively in Khulna region, Bangladesh and carbosulfan (trade name ‘Marshal’) is one of the most commonly used carbamate pesticide in this region Repeated application of this pesticide can stimulate growth of carbosulfan degrading microorganisms (Sahoo et al., 1998). This study focused on the selective isolation and characterization of a gram negative bacterial strain from brinjal (Solanum melongena) cultivated lands having a history of the usage of the pesticide “Marshal”
