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 ...

Sustainability of nutrient requirements for microbial proliferation on a large scale is a challenge in bioremediation processes. This article presents data on biochemical properties of a free cyanide resistant and total nitrogen assimilating fungal isolate from the rhizosphere of Zeamays (maize) growing in soil contaminated with a cyanide-based pesticide. DNA extracted from this isolate were PC...

A bacterium capable of metabolizing endosulfan (6,7,8,9,10,10-hexachloro-1,5,5a,6,9,9a-hexahydro-6,9-methano-2,4,3-benzodioxathiepine3-oxide) was isolated from cotton-growing soil and effectively shown to degrade endosulfan into endosulfan sulfate. The bacterium degraded 50% of the compound within 3 days of incubation. Endosulfan sulfate was the only terminal product and no other metabolites we...

The long-term presence of synthetic pesticides on agricultural land can lead to a decline in soil fertility. Synthetic inhibit the activity essential enzymes and suppress beneficial microbial populations for plants. One potential approach mitigate extent contamination caused by involves utilization indigenous pesticide-resistant bacteria. Several upland bacteria from Banyumas Regency, Central J...

The effects of repeated atrazine application (40 mg a.i.kg(-1)) on its degradation, microbial communities and enzyme activities were studied in a peat based biomixture composed by straw, soil and peat in the volumetric proportions of 2:1:1 that can be used in on-farm biopurification system. Atrazine removal efficiency was high (96%, 78% and 96%) after each atrazine application and did not show ...

Apple orchard surface soils in Japan are polluted with copper (Cu), lead (Pb), and arsenic (As) due to long-term use of metal-based pesticides. We investigated the effects of heavy metals accumulated in the surface soils in apple orchards on the microbial biomass and the microbial communities. Soil samples were taken from a chestnut orchard (unpolluted control) and five apple orchards with diff...

Globally, the rapid rise in human population has increased crop production, resulting pesticide xenobiotics. Despite fact that xenobiotics toxify soil environment and ecosystem, synthetic pesticides have agricultural yields reduced disease vectors. Pesticide use increased, an increase environmental pollution. Various methods of controlling eliminating these contaminants been proposed to address...

A biosensor is an analytical device which integrates a biological recognition element with a physical transducer to generate a measurable signal proportional to the concentration of the analyses. A microbial biosensor consists of a transducer in conjunction with immobilized viable or non-viable microbial cells. Non-viable cells obtained after Permeable or whole cells containing periplasmic enzy...
