“…Monocrotophos is weakly sorbed by soil particles because of its hydrophilic nature. Leaching of monocrotophos may pollute the groundwater, ultimately resulting in adverse effects on biological systems Bhalerao and Puranik, 2009). Together with its high mammalian toxicity, these characteristics make monocrotophos an ideal compound for decontamination and detoxification.…”

“…Rhodococcus phenolicus strain G2P T utilize phenol, chlorobenzene and chlorobenzoic acid as source of carbon (Marc and James, 2005). As a measure of bioremediation, soil fungi capable of degrading monocrotophos were isolated from various geographical and ecological sites (Bhalerao and Puranik, 2009). …”

Bacteria were isolated by enrichment culture technique from groundnut (Arachis hypogaea L.) soils and tested for their ability to degrade monocrotophos in mineral salts medium under aerobic conditions in the laboratory. Based on some of the morphological and 16S rRNA gene sequence analysis, the isolates were identified as Rhodococcus phenolicus strain MCP1 and Rhodococcus ruber strain MCP-2. The initial (0-day) recovery of monocrotophos in the culture medium was 94%; and by the end of 4 th day, about 21% of added monocrotophos was lost from the uninoculated medium. By the end of 1 st , 2 nd , 3 rd and 4 th day 13, 20, 24, 30% and 18, 33, 37, 45% of monocrotophos was degraded, by R. phenolicus strain MCP1 and R. ruber strain MCP-2 respectively, when the mineral salts medium was supplemented with monocrotophos as a C source. Simultaneously 12, 22, 26, 30% and 18, 26, 37, 40% of Nmethylacetoacetamide a metabolite of monocrotophos was recovered in the media inoculated with the R. phenolicus strain MCP1 and R. ruber strain MCP-2 respectively, during the same period. Decrease in the amount of monocrotophos with a concomitant increase in the level of N-methylacetoacetamide clearly indicates the degradation of parent compound.

“…Taking advantage and recognizing the biodegradable capabilities of fungi is therefore important, since these organisms have the ability to degrade a wide range of environmental pollutants (Gao et al 2010;Maiti et al 2013;Matsubara et al 2006;Pinto et al 2012;Purnomo et al 2013;Uhnáková et al 2011). Some filamentous fungi from Aspergillus' genera have already been reported to degrade organophosphorus compounds (Bhalerao and Puranik 2009) being A. fumigatus and A. terreus two of the most frequently found species isolated from pesticide-contaminated soils (Bordjiba et al 2001). Moreover, according to Ye et al (2011) and Silambarasan and Abraham (2012), these species are able to degrade anthracene and chlorpyrifos, respectively.…”

Relatively limited attention has been given to the presence of fungi in the aquatic environment compared to their occurrence in other matrices. Taking advantage and recognizing the biodegradable capabilities of fungi is important, since these organisms may produce many potent enzymes capable of degrading toxic pollutants. Therefore, the aim of this study was to evaluate the potential ability of some species of filamentous fungi that occur in the aquatic environment to degrade pesticides in untreated surface water. Several laboratory-scale experiments were performed using the natural microbial population present in the aquatic environment as well as spiked fungi isolates that were found to occur in different water matrices, to test the ability of fungi to degrade several pesticides of current concern (atrazine, diuron, isoproturon and chlorfenvinphos). The results obtained in this study showed that, when spiked in sterile natural water, fungi were able to degrade chlorfenvinphos to levels below detection and unable to degrade atrazine, diuron and isoproturon. Penicillium citrinum, Aspergillus fumigatus, Aspergillus terreus and Trichoderma harzianum were found to be able to resist and degrade chlorfenvinphos. These fungi are therefore expected to play an important role in the degradation of this and other pollutants present in the aquatic environment.

“…Many microbes including B. megaterium and A. atrocyaneus were reported to degrade MCP by producing enzymes like phosphatase and esterase [14]. Although bacterial isolates are very well known for the production of phosphatases however, there are limited studies regarding fungal phosphatases, which can serve as a useful tool to hydrolyze MCP [15]. The background study in our laboratory revealed Aspergillus niger ITCC 7782.10 as an efficient degrader of MCP [16].…”
