“…In fresh soil samples with and without inoculation, the degradation of malaoxon was 77.7% and 17.8% after 7 days respectively. In our recent study (Singh et al, 2012), we have reported that after inoculation of sterilized soil with strain KB1, the transformation of malathion increased to 68% during the same period (7 days). In fresh soil samples with and without inoculation, the degradation of malaoxon was 78 and 18% after 7 days, respectively.…”

“…Malathion irreversibly inactivates acetylcholinesterase (AChE) enzyme that breaks down acetylcholine, a chemical essential in transmitting nerve impulses across junctions between nerves [5]. Malathion degrading bacterial isolates have already been reported [1,6,7,9,10]. Fungi, Penicillium rotatum and Aspergillus niger, metabolized 76% and 59% of the malathion in the medium within 10 days through carboxylesteratic hydrolysis as well as by a demethylation process.…”

Degradation of a pesticide, malathion, in soil by Bacillus sp has been reported during current study. A simple and highly sensitive reverse phase HPLC-UV (High pressure liquid chromatography-Ultraviolet) method was used for determination of malathion degradation in soil. The bioremediation of was performed in malathion contaminated sterile and nonsterile soil and it was found that 84.81% and 74.11% of malaoxon, respectively, from malathion concentration of 1.5% kg −1 soil was degraded by strain PU after 7 days. Similarly, 63.31% and 57.14% of malaoxon in sterile and nonsterile soil respectively, from malathion concentration of 1.5% kg −1 soil was degraded by strain KB2 after 7 days. Bioremediation of malathion in soil using strain KB1 have already discussed in the previous study (Singh et al., 2012). Regardless of soil sterilization, incorporation of bacterial strain in malathion containing soil resulted in higher level of degradation of malathion. Bioremediation of malathion in soil was maximum for mixed culture of all three strains.

“…The degradation rate recorded was 20% malathion and 47% malaoxon out of the initial concentration of malathion. Two metabolites, mal‐monocarboxylic acid and mal‐dicarboxylic acid, were detected within 7 days at 30°C . The present study reports on the isolation, molecular characterization and biodegradation of malathion by Fusarium oxysporum .…”

“…Singh et al . demonstrated degradation of malathion by B. thuringiensis/cereus bacteria by performing two systems, soil slurry system and soil box system. After 4 days of incubation, it was found that 65.87% of malaoxon and 30.93% of malathion was degraded and in case of soil box system 74.75% of malaoxon and 26.12% of malathion was degraded.…”

The present work was focused in isolating fungus which possessed the special ability to degrade malathion. The pesticide of choice was malathion as it is being used to control a variety of pests in the agricultural fields in India. The fungal strains with the potential to degrade malathion was isolated by enrichment technique from malathion contaminated soil. The molecular characterization of 18S rRNA sequence homology confirmed its identity as Fusarium oxysporum. The isolate was able to degrade 400 mg L−1 malathion completely in mineral medium. In soil spiked with malathion and with addition of nutrients (carbon, nitrogen, phosphate), the isolate was capable of degrading malathion at 8th day of incubation. Where as in the second trial, in the absence of nutrients, JASA1 was able to degrade 400 mg L−1 malathion on the 9th day of incubation. The course of the degradation process was studied using High performance liquid chromatography (HPLC) and Fourier transform infrared (FTIR) analyses which confirmed the degradation potential of the fungus. © 2014 American Institute of Chemical Engineers Environ Prog, 34: 112–116, 2015
