“…To implement the Stockholm Convention on POPs, the Ministry of Ecology and Environment of China has prohibited the production, circulation, application, import, and export of lindane since 26 March 2019 (Wang, 2019). Lindane is still being used in some developing countries for agricultural and public health purposes due to its low cost and versatility in pest control (Abhilash and Singh, 2010). Currently, India is the largest producer and consumer of lindane in the world (Sagar and Singh, 2011).…”

Insights Into the Biodegradation of Lindane (γ-Hexachlorocyclohexane) Using a Microbial System

et al. 2020

Lindane (γ-hexachlorocyclohexane) is an organochlorine pesticide that has been widely used in agriculture over the last seven decades. The increasing residues of lindane in soil and water environments are toxic to humans and other organisms. Large-scale applications and residual toxicity in the environment require urgent lindane removal. Microbes, particularly Gram-negative bacteria, can transform lindane into non-toxic and environmentally safe metabolites. Aerobic and anaerobic microorganisms follow different metabolic pathways to degrade lindane. A variety of enzymes participate in lindane degradation pathways, including dehydrochlorinase (LinA), dehalogenase (LinB), dehydrogenase (LinC), and reductive dechlorinase (LinD). However, a limited number of reviews have been published regarding the biodegradation and bioremediation of lindane. This review summarizes the current knowledge regarding lindane-degrading microbes along with biodegradation mechanisms, metabolic pathways, and the microbial remediation of lindane-contaminated environments. The prospects of novel bioremediation technologies to provide insight between laboratory cultures and largescale applications are also discussed. This review provides a theoretical foundation and practical basis to use lindane-degrading microorganisms for bioremediation.

“…Organochlorines (OC) are the commonly used pesticides in agricultural field for crop protection in which lindane and endosulfan is most common insecticide. Lindane (hexachlorocyclohexane, HCH) contaminated soils can be found in most countries of the world (Abhilash and Singh 2010). Hans et al (1999) tested soil samples from dry bed of the River Ganges at Kanpur (India) and they reported pesticides HCH, dichlorodiphenyl trichloroethane (DDT) their isomers and metabolites in all the samples.…”

In the industrial area of Chinhat, Lucknow (India) wastewater coming from pesticide manufacturing and other industries is used to irrigate the agricultural crops. This practice has been polluting the soil and pollutants might reach the food chain. Gas chromatographic analysis revealed the presence of certain organochlorine pesticides in soil samples. Samples were extracted using different solvents, i.e., hexane, acetonitrile, methanol, chloroform, and acetone (all were HPLC-grade, SRL, India). Soil extracts were assayed for mutagenicity using Ames Salmonella/mammalian microsome test. Mutagenicity was observed in the test samples and TA98 was the most responsive strain for all the soil extracts (irrigated with wastewater) in terms of mutagenic index in the presence (+S9) and absence (-S9) of metabolic activation. In terms of slope (m) of linear dose-response curve for the most responsive strain TA98 exhibited highest sensitivity against the soil extracts in the presence and absence of S9 fraction. Hexane-extracted soil sample (wastewater) exhibited maximum mutagenicity in terms of net revertants per gram of soil in the presence and absence of S9 mix as compared to the other soil extracts. Groundwater-irrigated soil extracts displayed low level of mutagenicity as compared to wastewater-irrigated soil. The soil is accumulating a large number of pollutants due to wastewater irrigation and this practice of accumulation has an adverse impact on soil health.

“…Phytoremediation can use several different mechanisms f o r r e m e d i a t i n g c o n t a m i n a n t s i n c l u d i n g phytoaccumulation/phytoextraction, phytostabilization, and rhizosphere degradation (Batty and Dolan 2013). Unlike phytoremediation of heavy metals by extracting contaminants and accumulating them above-ground, the primary mechanism of phytoremediation of petroleumcontaminated soils is the provision of a biologically active soil region (i.e., the rhizosphere) by plant root systems which can encourage microbial degradation by stimulating the growth of related functional bacteria (Abhilash and Singh 2010).…”

Background and aims The objectives of this study were to elucidate the mechanisms of interaction between root exudates of tall fescue and functional bacteria associated with petroleum degradation and whether components of the exudates can enhance petroleum removal from soil. Methods Root exudates of tall fescue were collected through a continuous root exudate trapping system and identified by GC-MS. Chemotaxis, swarming, and in vitro assay were conducted to assess the effects of the organic acids of root exudates on Klebsiella sp. D5A (plant growth promoting rhizobacterium), Pseudomonas sp. SB (biosurfactant producing bacterium), and Streptomyces sp. KT (petroleum-degrading bacterium). A pot experiment with organic acid amendment was conducted to study the effects of these components of root exudates on petroleum remediation. Microbial physiological metabolisms affected by organic acids were tested using Biolog Eco plates. Results Palmitic acid was found to be most effective in promoting D5A colonization on tall fescue. ρ-Hydroxybenzoic and palmitic acids significantly stimulated the growth of strains D5A, SB, and KT. Furthermore, palmitic acid amendment significantly enhanced petroleum removal in pot experiment. Conclusions Palmitic acid was the critical organic acid t o f a c i l i t a t e p e t r o l e u m r e m o v a l d u r i n g phytoremediation. These findings provide insight into the mechanisms by which tall fescue enhances the degradation of petroleum.
