In the recent era, increasing persistence of hazardous contaminants is badly affecting globe in many ways. Due to high environmental contamination, almost every second species on earth facing worst issue their survival. Advances newer remediation approaches may help enhance bioremediation's quality, while conventional procedures have failed remove compounds from environment. Chemical and physical waste cleanup been used current circumstances; however, these methods are costly harmful Thus, there has a rise use bioremediation due an increase which led development genetically engineered microbes (GEMs). It safer more cost-effective microorganisms rather than alternative methods. GEMs created by introducing stronger protein into bacteria through biotechnology or genetic engineering desired trait. Biodegradation oil spills, halobenzoates naphthalenes, toluenes, trichloroethylene, octanes, xylenes etc. accomplished using such bacteria, fungus, algae. Biotechnologically induced powerful naturally occurring ones degrade faster because they can quickly adapt new pollutants encounter co-metabolize. Genetic worthy process that will benefit environment ultimately health our people.

Plant growth-promoting bacteria in metal-contaminated soil: Current perspectives on remediation mechanisms

Frontiers in Microbiology, Journal Year: 2022, Volume and Issue: 13

Published: Aug. 11, 2022

Heavy metal contamination in soils endangers humans and the biosphere by reducing agricultural yield negatively impacting ecosystem health. In recent decades, this issue has been addressed partially remedied through use of “green technology,” which employs metal-tolerant plants to clean up polluted soils. Furthermore, global climate change enhances negative effects climatic stressors (particularly drought, salinity, extreme temperatures), thus growth accumulation capacity remediating plants. Plant growth-promoting bacteria (PGPB) have widely introduced into improve productivity or efficiency phytoremediation metal-contaminated via various mechanisms, including nitrogen fixation, phosphate solubilization, phytohormone production, biological control. The plants, as well PGPB inoculants, should hasten process moving technology from laboratory field. Hence, it is critical understand how ameliorate environmental stress toxicity while also inducing plant tolerance, mechanisms involved such actions. This review attempts compile scientific evidence on topic, with a special emphasis mechanism bioremediation [plant promotion detoxification/(im)mobilization/bioaccumulation/transformation/translocation] deciphering combined (metal stresses) tolerance.

Published: May 27, 2024

The discovery of antibiotics and pesticides has greatly contributed to the social economic development human society but, due long-term irrational application, it led drug-resistant microorganisms, environmental damage, other hazards, so selection alternative natural, safe, non-hazardous bioactive substances is an effective solution for this problem. D-limonene a compound widely present in various plant essential oils, exhibiting excellent broad-spectrum bioactivity promising prospects clinical application. This review provides detailed overview biological activities D-limonene, emphasizing its antimicrobial, anthelmintic, insecticidal, medicinal potential. While nanoencapsulation technology shows promise improving physicochemical properties enhancing practical applications, also crucial comprehensively evaluate potential side effects before use.
