The ability of microorganisms to detoxify xenobiotic compounds allows them to thrive in a toxic environment using carbon, phosphorus, sulfur, and nitrogen from the available sources. Biotransformation is the most effective and useful metabolic process to degrade xenobiotic compounds. Microorganisms have an exceptional ability due to particular genes, enzymes, and degradative mechanisms. Microorganisms such as bacteria and fungi have unique properties that enable them to partially or completely metabolize the xenobiotic substances in various ecosystems.There are many cutting-edge approaches available to understand the molecular mechanism of degradative processes and pathways to decontaminate or change the core structure of xenobiotics in nature. These methods examine microorganisms, their metabolic machinery, novel proteins, and catabolic genes. This article addresses recent advances and current trends to characterize the catabolic genes, enzymes and the techniques involved in combating the threat of xenobiotic compounds using an eco-friendly approach.
Beekeeping is essential for the development of bio-economy practices; it provides tremendous social benefits on both economic and ecological fronts. The objectives of the present study were to explore the socioeconomic status of all traditional and modern beekeeping populations, the role of anthropogenic movement, manipulation, filthy beekeeping practices, bacterial pathogenesis, irrational use of antibiotics and the agricultural intensification of managed and native bee species in the selected study sites. The required data was collected through in-depth personal interviews and questionnaires. A total of 101 (42 traditional and 59 modern) beekeepers were interviewed from randomly selected five blocks in the Nainital district. Out of 18 selected study sites, 16 sites fall under rural areas, one is an urban town, namely Kathgodam and the remaining one is a town, namely Fatehpur Range. The present investigation reveals that 70% of total modern beekeepers are of 20-49 years old and reside in rural areas. It is encouraging that people have adopted beekeeping in rural areas for livelihood and modern purposes. During the present study, it was observed that females are least interested in beekeeping practices due to extensive touring and shifting to remote areas for qualitative nectar and pollen.
Insecticides are extensively used in agriculture to foil the crop yield losses. Due to long persistence in the environment insecticides cause undesirable effects on human health and environment. Most of the people especially farmers are the vulnerable section of population exposed to insecticides in different ways and degrees. This review briefs insecticide toxicity of the banned insecticides, their consumption and accidental exposure including the status and production in India. Since pesticides and their metabolites are harmful to the atmosphere causing human health hazards in terms of toxicity, it is essential to examine pesticide contamination and the health effects of pesticides on exposed health workers and other non-target organisms. Pesticide risk assessment on non-target organisms can be analyzed by using different test methods to determine the toxicity grade.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
