“…It has been generally considered that the enrichment and screening conditions of environmental microorganisms are crucial for the selection of desired degrading bacteria [22,23]. In this study, members of the genus Bacillus were considered potential pesticide bioremediation agents based on previous studies [24,25].

Strain CY-012 isolated from garden soil sprayed with pyrethroid pesticide was able to efficiently degrade fenvalerate. The bacterium was identified as Bacillus licheniformis based on its morphology, physiological and biochemical characteristics, and 16S ribosomal DNA gene analysis. Response surface methodology analysis showed that the optimum conditions for fenvalerate degradation were fenvalerate concentration of 44.04 mg L ¡1 , pH 7.48, and ferric chloride concentration of 0.051% (w/v). Under these conditions, approximately 80.07% of fenvalerate was degraded within 60 h of incubation. Five metabolic compounds, including a-isopropyl-4-chlorobenzene acetic acid, 4-chlorobenzene acetic acid, 3-phenoxybenzyl alcohol, phenol and benzoic acid were detected during fenvalerate degradation and identified by gas chromatography-mass spectrometry. A possible degradation pathway of fenvalerate was proposed based on these identified metabolites. The results indicated that strain CY-012 could potentially be used to eliminate environmental contamination with pyrethroid insecticides.

“…Contaminated sites are considered to be a good source for the isolation of pyrethroid-degrading microorganisms (Tables 3 , 4 ). Using enrichment culture techniques, several bacterial and fungal species belonging to various genera have been isolated from pyrethroid-contaminated soils (Wang et al, 2011 ; Cycoń et al, 2014 ; Akbar et al, 2015a ; Bhatt et al, 2016 ; Lee et al, 2016 ), sludge (Yuanfan et al, 2010 ; Chen et al, 2011a ; Sundaram et al, 2013 ; Xiao et al, 2015 ; Tiwary and Dubey, 2016 ), or wastewater (Lin et al, 2011 ; Zhang S. et al, 2011 ; Chen et al, 2014 ). For the effective use of microorganisms in the remediation of pyrethroid-contaminated soils, it is extremely important to determine the potential of these microorganisms for the degradation of pyrethroids under optimal conditions in liquid media.…”

Pyrethroid-Degrading Microorganisms and Their Potential for the Bioremediation of Contaminated Soils: A Review

Pyrethroid insecticides have been used to control pests in agriculture, forestry, horticulture, public health and for indoor home use for more than 20 years. Because pyrethroids were considered to be a safer alternative to organophosphate pesticides (OPs), their applications significantly increased when the use of OPs was banned or limited. Although, pyrethroids have agricultural benefits, their widespread and continuous use is a major problem as they pollute the terrestrial and aquatic environments and affect non-target organisms. Since pyrethroids are not degraded immediately after application and because their residues are detected in soils, there is an urgent need to remediate pyrethroid-polluted environments. Various remediation technologies have been developed for this purpose; however, bioremediation, which involves bioaugmentation and/or biostimulation and is a cost-effective and eco-friendly approach, has emerged as the most advantageous method for cleaning-up pesticide-contaminated soils. This review presents an overview of the microorganisms that have been isolated from pyrethroid-polluted sites, characterized and applied for the degradation of pyrethroids in liquid and soil media. The paper is focused on the microbial degradation of the pyrethroids that have been most commonly used for many years such as allethrin, bifenthrin, cyfluthrin, cyhalothrin, cypermethrin, deltamethrin, fenpropathrin, fenvalerate, and permethrin. Special attention is given to the bacterial strains from the genera Achromobacter, Acidomonas, Bacillus, Brevibacterium, Catellibacterium, Clostridium, Lysinibacillus, Micrococcus, Ochrobactrum, Pseudomonas, Serratia, Sphingobium, Streptomyces, and the fungal strains from the genera Aspergillus, Candida, Cladosporium, and Trichoderma, which are characterized by their ability to degrade various pyrethroids. Moreover, the current knowledge on the degradation pathways of pyrethroids, the enzymes that are involved in the cleavage of pesticide molecules, the factors/conditions that influence the survival of strains that are introduced into soil and the rate of the removal of pyrethroids are also discussed. This knowledge may be useful to optimize the environmental conditions of bioremediation and may be crucial for the effective removal of pyrethroids from polluted soils.

“…Since the restricted usage of high toxic organophosphate and organochlorine pesticides, pyrethroids cypermethrin (C22H19Cl2NO3) has been excessively applied in agriculture as a substitute (McCoy et al, 2012;Sundaram et al, 2013;Tiwary and Dubey, 2016). Due to its photostability and thermostability, cypermethrin was very persistent and had long half-life (94.2-1103.0 d) in natural environments (Chen et al, 2012b), which led to the accumulation of cypermethrin in soil (Shafer et al, 2005).…”

Cypermethrin is widely applied in agriculture practice and leads to serious soil contamination. Limited information is available on the bioremediation of cypermethrin-contaminated soil using biochar as a carrier for bacteria. In the present study, cypermethrin-degrading bacterial consortium immobilized on biochar was applied to cypermethrin contaminated soil (final content of biochar in soil was 0.5‰, 1‰ and 2‰ respectively) in pot experiments. The results demonstrated that cypermethrin degradation (30 mg•kg-1) in soil fitted the first order kinetic model. The treatment of biochar (0.5‰) with immobilized bacteria achieved the maximum specific degradation rate constant (0.0422 d-1) and removal rate (82.18%) of cypermethrin within 40 days, and shortest degradation half-life of cypermethrin (16.4 d) among all treatments. Furthermore, the results suggested that the biochar addition reduced the bioavailability of cypermethrin to bacteria and cypermethrin removal rate in soil. Two-way ANOVA analysis showed that promoting effect of bacterial consortium addition was stronger than that of biochar in sterilized soil, while biochar had more significant effect than bacteria in natural soil.
