Imidacloprid is an insecticide of systemic nature that exhibits an adverse impact on several non-target organisms. In the present study, potential bacteria have been isolated and used for biodegradation of imidacloprid in batch studies and stirred tank reactor. The optimum process condition for degradation has been found to be at pH 7, a temperature of 35 °C, and a shaking speed of 150 rpm. Maximum degradation of 78% has been achieved by the bacterial consortium in the batch study, while, in the reactor, it increases to 90%. Kinetics analysis suggests that the Teisser model best fits the experimental data, with a correlation coefficient (R 2) of 0.98. Ecotoxicological assessment using luminescent bacteria reveals 40% and 90% inhibition in luminescence in the case of untreated sample upon exposure for 30 min and 24 h, respectively, while the values obtained in the case of treated samples are 9% and 29%, respectively. Cytotoxicity assessment indicates 60% reduction in cell proliferation in untreated samples and <10% cell proliferation inhibition in treated samples, indicating a considerable decrease in toxicity post-bacterial treatment.

“…Pesticides such as organochlorines, organophosphates, pyrethroids, and carbamates are associated with detrimental effects including high environmental persistence, bioaccumulation, long-range transmission, and adverse effects to non-target organisms (Kumari et al, 2014;Kumar et al, 2019). Exposure to pesticides can for example cause different types of human cancer, teratogenic and genotoxic defects as well as endocrine and nerve dysfunction (Kim et al, 2017;Shah and Parveen, 2021).…”

Role of fungi in bioremediation of emerging pollutants

Advancements in chemical, medical, cosmetic, and plastic producing industries have improved agricultural yields, health and human life in general. As a negative consequence, a plethora of chemicals are intentionally and unintentionally released to terrestrial and aquatic environments with sometimes devastating effects for entire ecosystems. One mitigation strategy to counteract this pollution is bioremediation. Bioremediation is an umbrella term for biologically mediated processes during which an undesired compound is transformed, degraded, sequestered and/or entirely removed from the ecosystem. Organisms across all domains of life may mediate bioremediation; yet, fungi are particularly promising candidates. They possess metabolic capabilities to break down complex molecules which make fungi the ultimate degraders of recalcitrant organic matter in nature. Bioremediation by fungi, also termed mycoremediation, has been more frequently investigated in terrestrial than aquatic ecosystems, although fungi also thrive in lacustrine and marine environments. Here, we focus on mycoremediation of emerging pollutants in aquatic environments. In this context, we draw parallels between terrestrial and aquatic fungal taxa, and their role in mycoremediation. We discuss the ability of fungi to break-down (i) pesticides, (ii) pharmaceuticals and personal care products, (iii) plastics, both conventional types and (iv) bioplastics, and fungal role, (v) mitigation of heavy metal pollution. Furthermore, we (vi) discuss possible mycoremediation strategies in applied settings and highlight novel enzyme based mycoremediation strategies.

Aerial application of persistent, bioaccumulative organochlorine pesticide endosulfan on cashew plantations to protect it from mosquito bug has led to contamination of soil and water environments in several parts of South Canara region, India. Endosulfan and its toxic residues like endosulfan sulfate are posing several threats to non-target organisms including humans. Biotransformation of toxic compounds using indigenous microbial strains is considered as safe and cost effective technique in bioremediation. In the present work, the bacterial strain designated as ES-1, has been isolated from the soil by enrichment method. The bacterial strain was found to mineralize endosulfan ˃99% of 100 mg/l completely biotically after 14 days of incubation by forming unknown polar metabolites.Whereas, abiotic degradation resulted in formation of a toxic compound, endosulfan sulfate. Based on 16s rDNA sequence analysis, the strain ES-1 showed 99% similarity to Bacillus sp. The results from the work suggest that, this bacterial strain could be employed for remediation of endosulfan contaminated environments.
