“…The use of environmentfriendly approaches and toxic studies to achieve benefits for humans in all aspects has significantly increased in recent years. 5,5,23,25,26 Altogether, the present status of vector control research urges us to find out cost-effective, environmentfriendly, target-specific and biodegradable natural insecticides against Culex quinquefasciatus mosquitoes. 8,24 Previously, 15 reported on the entomocidal potential of five different plants such as Achyranthes aspera, Chenopodium murale, Trianthema portulacastrum, Convulvulus arvensis, and Tribulus terrestris against Culex quinquefasciatus.…”

Introduction: Plant-based knowledge has been used for generations for personal protection from various mosquito species. The notion of applying such traditional perspectives in vector control research has received extensive attention in recent years. Unlike other common patterns, the present investigation has tried to explore the augmented production of reactive oxygen species (ROS) in response to Stachytarpheta jamaicensis exposure with special inference on larvicidal potential, mode of action of phytochemical compounds, and oxidative stress. Methods: The larvicidal potential was determined as per the WHO protocol. Ultraviolet-visible spectroscopy was used to determine the excessive production of ROS. GC-MS was employed to characterise the phytochemical constituents. The statistical analysis was done by using SPSS version 24.0.0. Result: The acetone extract has been found to exhibit a maximum range of toxicity in terms of larvicidal potential and reactive oxygen species formation. Among the 40 phytochemical elements characterised, Cyclopropane, 1,1,2,2-Tetramethyl; Phenyl-Acetonitrile; Pyranone; Tetradecene; Neophytadiene; Mome Inositol; Monocrotaline; and Squalene may be responsible for the augmented production of ROS in the Culex quinquefasciatus. Conclusion: The phytochemical elements in Stachytarpheta jamaicensis displayed extensive toxicity and inhibited the normal development of Culex quinquefasciatus mosquitoes by augmented production of reactive oxygen species, indicating its prominent role in oxidative stress.

“…Heavy metal removal using microbes follows the principles of biosorption and bioaccumulation to remove heavy metals from the polluted environments [ 17 ]. The process of heavy metal biosorption involves the sorption and entrapping of heavy metals onto the outer lipid membrane and sometimes even on the exopolysaccharide secretions of the living or dead heavy metal sequester [ 43 ]. On the other hand, bioaccumulation involves the use of various transporters such as porins, ion channels, primary active transporters, and secondary transporters that transport heavy metals from the environment to microbial cytoplasm to be further bound by metal-sequestering proteins within the microbial cytoplasm [ 74 ].…”

According to the United Nations Environment Programme (UNEP), soil health is declining over the decades and it has an adverse impact on human health and food security. Hence, soil health restoration is a need of the hour. It is known that microorganisms play a vital role in remediation of soil pollutants like heavy metals, pesticides, hydrocarbons, etc. However, the indigenous microbes have a limited capacity to degrade these pollutants and it will be a slow process. Genetically modified organisms (GMOs) can catalyze the degradation process as their altered metabolic pathways lead to hypersecretions of various biomolecules that favor the bioremediation process. This review provides an overview on the application of bioengineered microorganisms for the restoration of soil health by degradation of various pollutants. It also sheds light on the challenges of using GMOs in environmental application as their introduction may affect the normal microbial community in soil. Since soil health also refers to the potential of native organisms to survive, the possible changes in the native microbial community with the introduction of GMOs are also discussed. Finally, the future prospects of using bioengineered microorganisms in environmental engineering applications to make the soil fertile and healthy have been deciphered. With the alarming rates of soil health loss, the treatment of soil and soil health restoration need to be fastened to a greater pace and the combinatorial efforts unifying GMOs, plant growth-promoting rhizobacteria, and other soil amendments will provide an effective solution to soil heath restoration ten years ahead.

“…Although mining of heavy metals and their usage in different industrial processes are caused a problem called "heavy metal pollution", they are important raw materials in industry and required for socio-economic development. Nevertheless, they are toxic and therefore a potential threat to human health and ecosystems [9][10][11]. They are major threats to living organisms, as they tend to be bioaccumulated and do not degrade easily in nature, and as mentioned above, some of them can be toxic even at low concentrations [4,12].…”

Nowadays, increased population and traffic density, together with the development of industry, caused increasing levels of heavy metals releasing to the environment, and environmental pollution has reached its highest level worldwide. Chemical products, fertilizers, industrial dyes, construction materials, silver dental fillings and vaccines are some of the well-known sources of heavy metals exposed the environment. Toxic heavy metals can normally be present in body parts of living things at very low levels, but at higher concentrations they can show toxic effects depending on species and duration. Among heavy metals, cadmium is one of the most harmful ones to the environment, humans, animals and plants, and can be toxic even at low concentrations. Thus in this study, Cd was applied to the wheat (Triticum aestivum L.) plants grown in Kyrgyzstan in different concentrations (0, 50, 100, 200 and 400 μM for experimental groups) and in addition to accumulations in different plant parts, some growth, development, physiological and anatomic parameters were measured. As a result, it was observed that wheat plants were affected by all Cd concentrations, although they were able to manage lower stress in terms of some parameters. It was also seen that plants were negatively affected by higher levels of Cd stress, although remained alive throughout the experimental period.
