“…These results agree [4,5], which reported the derivative ability of cyanobacterial mats for Acetochlor and Diuron. Further support to our results is in Singh et al [29] report that stated higher levels of Malathion degradation in soil due to a mixed culture of three bacterial strains. In contrast, Ibrahim et al [30] investigated the growth of three strains of filamentous cyanobacteria under different concentrations of Malathion and found a sharp decrease in the growth of filamentous cyanobacterial by increasing the concentration of Malathion.…”

“…Janeczko et al (2014) demonstrated that activated sludge can degrade malathion in laboratory-scale bioreactors. There is also circumstantial evidence showing that isolates common to activated sludge can biodegrade malathion (Singh et al, 2013). These findings stand in contrast to the results of Tsezo and Bell (1991), who used radiolabeling to demonstrate that sorption and abiotic degradation, not microbial activity, were primarily responsible for malathion removal in activated sludge.…”

This study evaluated the effect of a VX (O-ethyl S-[2-(diisopropylamino)ethyl] methylphosphonothioate) surrogate (malathion) on the activity, performance, and ecology of activated sludge bioreactors. In the presence of malathion, the maximum observed respiration rates varied between 43 and 53 μg/O 2 min, generally similar to the 49 μg O 2 /min rates observed in controls. Malathion did not alter the respiration ratio of O 2 consumed-to-CO 2 produced nor did it impact the shape of the oxygen consumption curves during respirometry. Shorter term (12 h) batch tests showed that both chemical oxygen demand (COD) and ammonia removal were not negatively impacted by the presence of 0.1-3 mg/L malathion. Longer term continuous addition (i.e. 40 days) of 0.1 mg/L of malathion also had no effect on COD and ammonia removal. In contrast to shorter term exposures, longer term continuous addition of 3 mg/L of malathion negatively impacted both COD and nitrogen removal and was associated with shifts in the abundance of species that are common to activated sludge. These results illustrate the impact that chemicals like malathion may have on COD removal, and nitrification, as well as the robustness of activated sludge microbial communities.

“…has also been reported. Residual malathion was monitored by HPLC analysis and it was found that 74.11% of malaoxon (an analog of malathion) was degraded by the strain (Singh et al, 2013). Similarly, Singh et al (2012) reported the degradation of malathion by Brevibacillus sp.…”

Malathion, a well-known organophosphate pesticide, has been used in agriculture over the last two decades for controlling pests of economically important crops. In the present study, a single bacterium, ML-1, was isolated by soilenrichment technique and identified as Bacillus licheniformis on the basis of the 16S rRNA technique. The bacterium was grown in carbon-free minimal salt medium (MSM) and was found to be very efficient in utilizing malathion as the sole source of carbon. Biodegradation experiments were performed in MSM without carbon source to determine the malathion degradation by the selected strain, and the residues of malathion were determined quantitatively using HPLC techniques. Bacillus licheniformis showed very promising results and efficiently consumed malathion as the sole carbon source via malathion carboxylesterase (MCE), and about 78% malathion was degraded within 5 days. The carboxylesterase activity was determined by using crude extract while using malathion as substrate, and the residues were determined by HPLC. It has been found that the MCE hydrolyzed 87% malathion within 96 h of incubation. Characterization of crude MCE revealed that the enzyme is robust in nature in terms of organic solvents, as it was found to be stable in various concentrations of ethanol and acetonitrile. Similarly, and it can work in a wide pH and temperature range. The results of this study highlighted the potential of Bacillus licheniformis strain ML-1 as a biodegrader that can be used for the bioremediation of malathion-contaminated soil.
