Glyphosate is currently one of the most used organophosphorus herbicides in world and its accumulation translocation soil wave causes environmental pollution biological health problems. A new approach to problem provided by preparation cerium nitrogen co-doped titanium dioxide composite nano-photocatalysts loaded on modified oyster shell powder (CeNT@Oys) a simple hydrothermal synthesis. The ph...

New derivatives of cyclodextrins were prepared in order to determine the relative importance of the structural key elements involved in the degradation of organophosphorus nerve agents. To avoid a competitive inclusion between the organophosphorus substrate and the iodosobenzoate group, responsible for its degradation, the latter group had to be covalently bound to the cyclodextrin scaffold. Al...

organophosphorus compounds are highly toxic chemicals that have application in production of warfare agents and agricultural pesticides. detoxification of areas that have been exposed to these types of materials is of vital importance and several approaches have been used for this purpose. biodegradation of organophosphates is one of these approaches that is in the center of attention due to it...

A bifunctional fusion protein consisting of organophosphorus hydrolase (OPH) and elastin-like polypeptide (ELP) was synthesized for the detoxification of organophosphorus compounds. ELPs undergo a reversible phase transition upon an increase in temperature, forming hydrophobic aggregates. This thermally triggered property of phase transition allows for a simple and rapid means of purifying the ...

Pseudomonas sp. strain 1-7, isolated from organophosphorus-polluted sludge, is able to degrade many organophosphorus compounds. Here, we report the draft genome sequence of Pseudomonas sp. strain 1-7.

Chemical contamination of natural and agricultural habitats is an increasing global problem and a major threat to sustainability and human health. Organophosphorus (OP) compounds are one major class of contaminant and can undergo microbial degradation, however, no studies have applied system-wide ecogenomic tools to investigate OP degradation or use metagenomics to understand the underlying mec...

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...

Synthetic organophosphorus compounds (OP) are widely used in agriculture to control agricultural and household pests. The excessive use of OP compounds have generated a number of environmental problems such as contamination of air, water and terrestrial ecosystems, harmful effects on different biota, and disruption of biogeochemical cycling. Therefore, there is a need for economical and dependa...
