Degradation of chlorpyrifos in laboratory soil and its impact on soil microbial functional diversity.
Degradation of chlorpyrifos at different concentrations in soil and its impact on soil microbial functional diversity were investigated under laboratory condition. The degradation half-live of chlorpyrifos at levels of 4, 8, and 12 mg/kg in soil were calculated to be 14.3, 16.7, and 18.0 d, respectively. The Biolog study showed that the average well color development (AWCD) in soils was signifi...
متن کاملEffects of soil pH on the biodegradation of chlorpyrifos and isolation of a chlorpyrifos-degrading bacterium.
We examined the role of microorganisms in the degradation of the organophosphate insecticide chlorpyrifos in soils from the United Kingdom and Australia. The kinetics of degradation in five United Kingdom soils varying in pH from 4.7 to 8.4 suggested that dissipation of chlorpyrifos was mediated by the cometabolic activities of the soil microorganisms. Repeated application of chlorpyrifos to th...
متن کاملBiodegradation of fungicide Thiram (TMTD) in soil under laboratory conditions
In vitro studies were carried out, using four selective media, to determine the effect of the main groups of soil microorganisms on the degradation of fungicide Thiram in soil. Soil from El Geraif (East Khartoum) that had no history of pesticide exposition was chosen to conduct this experiment. In general, Thiram have a fluctuating effect on the growth of organic nitrogen using bacteria up to 1...
متن کاملBiodegradation of chlorpyrifos by enterobacter strain B-14 and its use in bioremediation of contaminated soils.
Six chlorpyrifos-degrading bacteria were isolated from an Australian soil and compared by biochemical and molecular methods. The isolates were indistinguishable, and one (strain B-14) was selected for further analysis. This strain showed greatest similarity to members of the order Enterobacteriales and was closest to members of the Enterobacter asburiae group. The ability of the strain to miner...
متن کاملPhenol Biodegradation Kinetics in the Presence of Supplimentary Substrate
Biodegradation of phenol in the presence of glucose as a supplementary substrate was investigated with mixed microbial consortium isolated from waste effluent of coke-steel factory. Batch experiments were carried out at room temperature and pH value of 7. Initial phenol and glucose concentrations were in the range of 25-1000 mg/l and 500-3000 mg/l, respectively. In a dual substrates system the ...
