Microbial Bioremediation for Environmental Sustainability: Recent Developments
AI summary Read the abstract
This review pulls together recent research on using bacteria and other microbes to clean up pollution, including plastics, microplastics, antibiotics, heavy metals, and oil, by having them break down or absorb harmful substances. This matters because microplastics and chemical pollutants increasingly end up in our water, food, and bodies, and finding natural ways to remove them could reduce our long-term exposure. That said, the authors note this technology still faces real hurdles, like working too slowly, sometimes creating toxic byproducts, and lacking real-world testing, so it's not yet a ready-made solution.
Microbial bioremediation has become an interesting and sustainable technique for dealing with pollution of the environment through microbial degradation, transformation, immobilization, and recovery of contaminants. This review looks into recent developments of microbial bioremediation with focus on pollutants such as wastewater, pharmaceuticals and antibiotics, heavy metals, petroleum hydrocarbons, plastics, microplastics and other emerging pollutants. Mechanisms employed by microbes include biodegradation, biosorption, bioaccumulation and biotransformation together with advancements in the use of bioaugmentation, microbial consortia, microbial electrochemical systems, omics technology, and genetically modified microbes. The reviewed research shows that microbial technologies have the potential of providing efficient pollutant management as well as resource recovery in the form of biogas, microbial biomass, biopolymers, nutrients and metals, thus making circular economy possible. However, some limitations like slow degradation rate, incomplete mineralization, formation of toxic metabolites, instability of the microbes, antibiotic resistance, lack of field studies, scalability issues and biosafety concerns are evident. Future studies should focus on long-term field investigations, realistic environmental matrix, understanding of microbial community dynamics, transformation product identification and use of advanced biotechnology, life cycle assessment and process engineering. In general, microbial bioremediation holds great promise towards sustainable future but development of efficient, safe, scalable, resource recovery and human relevant technologies is crucial.

Microbial Bioremediation of Microplastics
AI summary Read the abstract
Tiny plastic bits called microplastics are now everywhere in our environment—and even in our bodies—raising concerns about long-term health effects. This review paper rounds up what scientists currently know about using bacteria and other microbes to break down these plastic particles, a promising cleanup strategy, while also pointing out the challenges researchers still need to solve before it works at scale. The takeaway: nature may offer tools to help tackle plastic pollution, but we're not there yet, so reducing microplastic use in the first place still matters for protecting our health.

Microbial and multi-omics approaches for bioremediation of emerging contaminants: environmental impact and future engineering solutions
AI summary Read the abstract
This research review summarizes how scientists are using helpful microbes (bacteria, fungi, and algae) to clean up dangerous pollutants in our water and soil, including pharmaceuticals, pesticides, and microplastics that can harm human health. The study shows that these tiny organisms can naturally break down and remove many toxic chemicals from the environment. This matters because it could lead to cheaper, eco-friendly ways to clean up contaminated areas and protect our drinking water and food supply.
Microbial plastic and microplastic bioremediation and innovations
AI summary Read the abstract
Scientists are studying certain bacteria and fungi that can naturally "eat" plastic, breaking it down using special enzymes instead of letting it pile up in landfills and oceans. This review paper rounds up what researchers have learned so far, including new tech that could speed up this microbial cleanup process, but notes there are still real challenges before it can be used on a large scale. This matters because as plastic waste breaks down into microplastics that contaminate our water, food, and even our bodies, finding safer ways to eliminate plastic pollution could reduce our long-term exposure to these particles.
