Abstract—In the present study, presence of endosulfan, imidacloprid, carbendazim, in the soil /vegetables/cereals and water samples was observed in agriculture fields of Uttarakhand. In view of biodegradation of these pesticides, 9 bacterial isolates were recovered from the soil samples of the fields which tolerated endosulfan, imidacloprid, carbendazim from 100 to 200 μg/ml. Three bacterial co...

Microbes inhabiting the phyllosphere of crops are exposed to pesticides applied either directly onto plant foliage or indirectly through soil. Although, phyllosphere microbiology has been rapidly evolving, little is still known regarding the impact of pesticides on the epiphytic microbial community and especially on fungi. We determined the impact of two systemic pesticides (metalaxyl and imida...

Food security and safety are the major concern in ever expanding human population on the planet earth. Each and every year insect pests cause a serious damage in agricultural field that cost billions of dollars annually to farmers. The loss in term of productivity and high cost of chemical pesticides enhance the production cost. Irrespective use of chemical pesticides (such as Benzene hexachlor...

To assess the impact of pollution induced by pesticides on Pacific oyster, Crassostrea gigas, health in France, in vivo effects of combined pesticide exposure and bacterial challenge on cell activities and gene expression in hemocytes were tested using flow cytometry and real-time PCR. As a first step, an in vivo model of experimental contamination was developed. Pacific oysters were exposed to...

We studied the growth and capacities for pesticides removal of bacterial strains isolated from the Laguna Grande, an oligotrophic lake at the South of Spain (Archidona, Málaga). Strains were isolated from water samples amended with 10 and 50 microg/ml of nine pesticides: organochlorinated insecticides (aldrin and lindane), organophosphorous insecticides (dimetoate, methyl-parathion and methidat...

Background and purpose: In Iran, Organ phosphorus pesticides such as chloropyrifos and diazinon are widely used in agriculture. These compounds inhibit activity of cholinesterase in nearly irreversible manner resulting in malfunction of nerve impulse transmission. This result in humans can produce illness or even death. Therefore, the present study aims to isolate various bacterial strains...

organochlorine pesticides are as environmental pollutants which have a high half-life and transmit from food chain to human and cause side effects such as mutations in different genes and finally cancer. in this research, after sampling and quantitative and qualitative of organochlorine residue, biodegradation of alpha, beta and gamma hexachlorobenzene (linden), ddt, aldrin, dieldrin, endosulfa...

BACKGROUND AND METHODS Assessing the effects of pesticide hazards on microbiological processes in the soil is currently based on analyses that provide limited insight into the ongoing processes. This study proposes a more comprehensive approach. The side effects of pesticides may appear as changes in the expression of specific microbial genes or as changes in diversity. To assess the impact of ...

Although most pesticides sprayed on terrestrial plants remain on their leaf surfaces, the relationship between leaf-associated microbial populations and pesticide degradation remains unclear. Here we examined changes in the bacterial community composition in the rape phyllosphere after treatment with dichlorvos, an organophosphorus pesticide. Results indicate that the bacterial community showed...
