Organophosphate compounds and their biodegradation; using enzymes as an increased efficiency approach

Organophosphorus compounds are widely used in pesticides, insecticides in agriculture and as nervous chemical agents. These chemicals inhibit the acetylcholinesterase enzyme activity that is responsible for the nervous impulse in organisms. This effect leads to an increase in acetylcholine level and finally neuronal complications. Many methods are used to degrade and decontaminate these compou...

 بقایای آزینفوس متیل و دیازینون در رودخانه های قره سو و گرگان رود استان گلستان

Background and Aim: insecticides are widely used for protecting of agriculture and stored products. Organophosphorus insecticides are used more than other pesticides in agriculture. Therefore the residue of these insecticides in environment such as water may be hazardous to human health. Golestan Province is one of the important agricultural zones in north of Iran. In this area, azinphosmetyl a...

Insecticide Resistance Characteristics of Diamondback Moth

Resistance to organophosphorus, carbamate and pyrethroid insecticides in the diamondback moth, Plutella xylostella (L.) is widespread in Japan. Consequently, tertiary amines such as cartap and thiocyclam, microbial insecticides (formulations of Bacillus thuringiensis Berliner) and chitin synthesis inhibitors have been widely used for control. A high level of resistance to these alternative inse...

Comparative degradation of organophosphorus insecticides in soil: specificity of enhanced microbial degradation

Laboratory experiments investigated the comparative degradation of six organophosphorus insecticides in soil as affected by enhanced microbial degradation. The degradation rates and product distributions of chlorpyrifos, fonofos, ethoprop, terbufos, and phorate were not dramatically altered in soils containing microbial populations adapted to rapidly degrade isofenphos. An Arthrobacter sp. isol...
