Exploring the Potential of Endophytic Microorganisms and Nanoparticles for Enhanced Water Remediation

Molecules, Год журнала: 2024, Номер 29(12), С. 2858 - 2858

Опубликована: Июнь 16, 2024

Endophytic microorganisms contribute significantly to water bioremediation by enhancing pollutant degradation and supporting aquatic plant health resilience releasing bioactive compounds enzymes. These inhabit tissues without causing disease or any noticeable symptoms. Endophytes effectively aid in eliminating contaminants from systems. Nanoparticles serve as potent enhancers processes, augmenting the efficiency of increasing surface area bioavailability, thereby improving efficacy rate remediation. Their controlled nutrient release ability stabilize endophytic colonization further enhanced sustainable elimination contaminated environments. The synergistic effect endophytes nanoparticles remediation has been widely explored recent studies, revealing compelling outcomes. Water pollution poses significant threats human health, ecosystems, economies; hence, sixth global goal Sustainable Development Agenda 2030 United Nations aims ensure availability management resources, recognizing their crucial importance for current future generations. Conventional methods addressing exhibit several limitations, including high costs, energy-intensive production hazardous by-products, insufficient effectiveness mitigating emerging pollutants such pharmaceuticals microplastics. Noticeably, there is an inability remove various types pollutants, thus resulting incomplete purification cycles. Nanoparticle-enhanced offers innovative, eco-friendly alternative degrading contaminants. A growing body research shown that integrating with a viable alternative.

The scale of nanoparticle use in consumer goods has grown exponentially over several decades owing to the unique properties materials this size range. At same time, well-defined end life cycle disposal strategies have not been developed for most materials, meaning that we are approaching potential a new ecological disaster with release millions metric tons nanoparticles into waste stream. field nanotoxicology meet challenge investigating hazards these and already identified toxicity mechanisms affect multiple tropes life. However, there stipulations on how applicable many results real world applications. These limitations largely arise from complex network variables must be considered during investigations. Herein, focus challenges posed by transformations undergo when they introduced biological environment. For example, biomolecules, such as proteins, rapidly coat shell, called corona, can modulate core and/or aid its internalization cells. As such, unlike evaluation small molecule toxicity, one cannot assume know composition nanoparticle-biomolecule species at any given time. This additional layer complication, well noncovalent nature made it difficult identify consistent trends. In Perspective, highlight current analysis difficulties studying nanotoxicity, recent advances studies, efforts reduce nanotoxicity outline remaining challenges.
