The methyl carbamate-degrading hydrolase (MCD) of Achromobacter WM111 has considerable potential as a pesticide bioremediation agent. However this potential has been unrealisable until now because of an inability to express MCD in heterologous hosts such as Escherichia coli. Herein, we describe the first successful attempt to express appreciable quantities(More)
Tobacco is an important cash crop of Pakistan. Pesticides are commonly used to increase the crop yield, but their health impact has not been studied yet. The objectives of the study were to determine the frequency of pesticide poisoning and to explore the knowledge, attitudes and practices (KAP) towards safety measures among the tobacco farmers in Swabi,(More)
The study aimed to determine the hazardous health effects of pesticides exposure in the factory workers by measuring plasma cholinesterase (PChE), pesticides residues, and renal and hepatic biochemical markers. In addition, we also assessed the knowledge, attitudes, and safety practices adopted by the industrial workers. The study was conducted in three(More)
The toxicity of organophosphates to a wide range of organisms necessitates the study of their degradation. We designed a study to isolate an organophosphate-degrading bacterium and to detect the gene involved in the hydrolysis of organophosphates. The bacterial strain was isolated by the enrichment culture technique from organophosphate-contaminated soil,(More)
Phosphotriesterases (PTEs) have been isolated from a range of bacterial species, including Agrobcaterium radiobacter (PTEAr), and are efficient enzymes with broad substrate ranges. The turnover rate of PTEAr for the common organophosphorous insecticide malathion is lower than expected based on its physical properties; principally the pka of its leaving(More)
Synthetic organophosphorous pesticides (OPs) are highly toxic compounds used widely, amounting to about 38% of the world-wide pesticides. The enormous and inadequate use of OPs is a continuous threat for the whole ecosystem due to their persistence and toxicity. This study was designed to isolate chlorpyrifos degrading bacteria from indigenous soil. After(More)
Organochlorinated pesticides OCs are highly toxic due to their persistence and severe ill effects on ecosystem. OCs were used extensively for agricultural as well as for health purposes like DDT, used for controlling malaria etc. OCs persistence and bioaccumulation create lot of health hazards including cancer, nervous system disorders, and tumor etc. Due(More)
