Biodegradation of synthetic organic pollutants: principles, progress, problems, and perspectives

mycolabadmin

This comprehensive review explains how bacteria naturally break down synthetic pollutants in our environment through various mechanisms. Scientists use advanced tools like gene sequencing and computer analysis to identify which bacteria degrade specific pollutants, how quickly they work, and what intermediate products form. Understanding these bacterial degradation pathways helps us develop better strategies to clean up contaminated water and soil in an environmentally friendly way.

Sorption–Biological Treatment of Coastal Substrates of the Barents Sea in Low Temperature Using the Rhodococcus erythropolis Strain HO-KS22

mycolabadmin

Scientists tested a method to clean oil-polluted beaches and sandy areas in the Arctic Barents Sea using a special bacteria strain combined with absorbing materials. The treatment worked well for sandy areas contaminated with lighter oils, speeding up natural cleanup by 3-4 times in the first month. The use of activated carbon or vermiculite prevented pollutants from washing back into the sea, protecting marine ecosystems.

Bibliometric analysis of global research on white rot fungi biotechnology for environmental application

mycolabadmin

White rot fungi are special mushrooms that can break down difficult-to-decompose pollutants in soil and water, offering a natural and cost-effective way to clean up environmental contamination. This research study analyzed over 3,900 scientific publications about using these fungi for environmental cleanup from 2003 to 2020. The analysis found that research on white rot fungi has grown significantly, with scientists from China and the USA leading the field, and identified three major application areas: treating biomass waste, removing dyes from wastewater, and cleaning polluted environments.

Microbes’ role in environmental pollution and remediation: a bioeconomy focus approach

mycolabadmin

Microbes like bacteria and fungi can break down pollutants and transform harmful waste into useful products through biological processes called bioremediation. By employing these naturally occurring or genetically modified microorganisms, we can clean up contaminated soil and water while producing valuable products like proteins and biofuels. This approach offers an environmentally friendly and economically sustainable solution to waste management that reduces pollution while creating a circular bioeconomy.

Recent advances in microbial engineering approaches for wastewater treatment: a review

mycolabadmin

This review explains how microorganisms like bacteria, fungi, and algae can clean polluted water more effectively and cheaply than traditional methods. These microbes break down harmful chemicals, remove heavy metals, and clean industrial waste. Using multiple types of microbes together (microbial consortium) works better than using a single type, making it an environmentally friendly and economical solution for treating wastewater worldwide.

Mycoremediation: Expunging environmental pollutants

mycolabadmin

Fungi can be used to clean up environmental pollution from industrial waste, pesticides, and heavy metals. Unlike expensive chemical treatments, fungal mycoremediation is cost-effective and environmentally friendly. Fungi produce natural enzymes that break down harmful pollutants into harmless substances, making it a promising solution for protecting soil and water contamination.

Biodecolorization and Biodegradation of Methyl Orange by Immobilized Pseudomonas aeruginosa Bacterium into SA/PVA Matrix Integrated with MOF UiO-66 Adsorbent

mycolabadmin

Scientists created special beads containing bacteria and a porous material called MOF to remove orange dye (methyl orange) from contaminated water. The bacteria break down the dye molecules while the porous material helps trap the dye, working together more effectively than either method alone. These beads removed over 92% of the dye from water in just 10 days, making them promising for treating textile industry wastewater.

Effect of nano-TiO2 size and utilization ratio on the performance of photocatalytic concretes; self-cleaning, fresh, and hardened state properties

mycolabadmin

Scientists developed a new type of concrete that can clean itself by breaking down pollutants in water using nano-sized titanium dioxide particles and sunlight. The study tested different sizes and amounts of these nanoparticles to find the best combination for removing textile dyes from wastewater. While the larger nanoparticles worked better for photocatalytic cleaning, the smaller ones made the concrete stronger, suggesting a trade-off between cleaning ability and structural durability.

Screening, identification, metabolic pathway of di-n-butyl phthalate degrading Priestia megaterium P-7 isolated from long-term film mulched cotton field soil in Xinjiang

mycolabadmin

This research identifies a special bacterium called Priestia megaterium P-7 that can efficiently break down di-n-butyl phthalate (DBP), a harmful plastic chemical that accumulates in cotton field soils. Scientists found that this bacterium can completely remove DBP from contaminated soil within 20 hours under optimal conditions. By studying the bacterium’s genes and metabolism, they discovered the specific enzymes and pathways it uses to degrade DBP into harmless compounds. This finding offers a practical biological solution for cleaning up contaminated agricultural soils, particularly in Xinjiang where plastic film mulching is widely used in cotton farming.
