“…Some studies proposed that the degradation proceeds through two dichloroeliminations, resulting in the formation of 3,4,5,6-tetrachloro-1-cyclohexene (γ-TCCH) followed by 5,6-dichlorocyclohexa-1,2-diene. Chlorobenzene is then produced by a dehydrochlorination reaction (Saez et al, 2017). Another anaerobic degradation pathway produces pentachlorocyclohexene (PCCH) followed by 1,2-dichlorobenzene (1,2-DCB) and 1,3-dichlorobenzene (1,3-DCB) (Quintero et al, 2005a,b).…”

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

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.

“…Since the 1940s, lindane and mixtures of HCH isomers, such as technical-grade HCH, were heavily used as insecticides . Technical-grade HCH consisted of a mixture of α (60–70%), β (5–12%), γ (10–15%), and δ (6–10%) isomers. , During manufacturing and application of lindane and technical-grade HCH, large quantities of HCH were improperly disposed, leading to widespread heavy soil contamination. − Although the use of HCH is restricted or completely banned in most countries, HCH isomers are still detected in water, soil, sediments, plants, and animals all over the world. − HCH isomers are recalcitrant, bio-accumulating, neurotoxic, teratogenic, and carcinogenic , and were included in the Stockholm Convention list of persistent organic pollutants in 2009…”

Intensive historical and worldwide use of pesticide formulations containing hexachlorocyclohexane (HCH) has led to widespread contamination. We derived four anaerobic enrichment cultures from HCH-contaminated soil capable of sustainably dechlorinating each of α-, β-, γ-, and δ-HCH isomers stoichiometrically to benzene and monochlorobenzene (MCB). For each isomer, the dechlorination rates, inferred from production rates of the dechlorinated products, MCB and benzene, increased progressively from <3 to ∼12 μM/day over 2 years. The molar ratio of benzene to MCB produced was a function of the substrate isomer and ranged from β (0.77 ± 0.15), α (0.55 ± 0.09), γ (0.13 ± 0.02), to δ (0.06 ± 0.02) in accordance with pathway predictions based on prevalence of antiperiplanar geometry. Data from 16S rRNA gene amplicon sequencing and quantitative PCR revealed significant increases in the absolute abundances of Pelobacter and Dehalobacter, most notably in the α-HCH and δ-HCH cultures. Cultivation with a different HCH isomer resulted in distinct bacterial communities, but similar archaeal communities. This study provides the first direct comparison of shifts in anaerobic microbial communities induced by the dechlorination of distinct HCH isomers. It also uncovers candidate microorganisms responsible for the dechlorination of α-, β-, γ-, and δ-HCH, a key step toward better understanding and monitoring of natural attenuation processes and improving bioremediation technologies for HCH-contaminated sites.

The present study focuses and assures the need for pesticide degradation from various water bodies used for irrigation and the available technologies to treat them effectively. A thorough review of the literature is done on pesticide residues present in various irrigation water sources like rivers, groundwater, river sediments, and soil which signifies the existence of pesticides in the ecosystem.This indicates the severity of water pollution due to various sources around and their adverse effect on the ecosystem. However, several technologies are available to treat these pesticides based on the classification. A Cross comparison between the technologies is done to determine the efficient technology for the treatment of irrigation water.
