Editorial: Pharmaceutically active micropollutants – how serious is the problem and is there a microbial way out?

mycolabadmin

Medicines we take don’t fully disappear—30 to 90% are excreted unchanged and end up in water supplies. These pharmaceutical residues contaminate drinking water and harm aquatic life worldwide. Scientists are discovering that certain fungi and bacteria can break down these drug residues through natural metabolic processes. By harnessing these microbes in treatment systems and improving waste management practices, we could significantly reduce pharmaceutical pollution.

Bioremediation Potential of a Non-Axenic Cyanobacterium Synechococcus sp. for Municipal Wastewater Treatment in the Peruvian Amazon: Growth Kinetics, Ammonium Removal, and Biochemical Characterization Within a Circular Bioeconomy Framework

mycolabadmin

Researchers discovered that a cyanobacterium called Synechococcus sp., when grown in diluted municipal wastewater, can effectively clean polluted water by removing 95% of ammonia while simultaneously producing valuable biomass. This dual-purpose approach offers a sustainable solution for wastewater treatment in the Peruvian Amazon, where conventional treatment infrastructure is limited but sunlight and warm temperatures are abundant. The organism produces useful compounds like phycocyanin, which has applications in food coloring, cosmetics, and pharmaceuticals, turning a pollution problem into a resource opportunity.

The microbial strategies for the management of chemical pesticides: A comprehensive review

mycolabadmin

Chemical pesticides used to protect crops contaminate soil and water, harming both ecosystems and human health. Scientists have discovered that specific microorganisms—bacteria, fungi, and algae—can naturally break down these harmful pesticides into harmless substances. By using advanced technologies to understand how these microbes work and even genetically enhancing them, researchers are developing sustainable solutions to clean up pesticide-contaminated environments without the toxic side effects of traditional cleanup methods.

Selected rhizobacteria strains improved the tolerance of Vicia faba plants to microcystins contaminated irrigation water and reduced human health risk

Farmers in semi-arid regions like Morocco often irrigate crops with water containing toxic cyanobacterial compounds called microcystins, which accumulate in food crops and harm human health. This study showed that inoculating faba bean plants with beneficial soil bacteria, particularly Achromobacter marplatensis, reduced microcystin accumulation in plants by 36% and promoted healthier plant growth despite contaminated water. The approach offers an affordable, sustainable solution to protect food crops in areas with microcystin-contaminated irrigation water.

Biodegradation of Microcystins by Aquatic Bacteria Klebsiella spp. Isolated from Lake Kasumigaura

Scientists discovered three bacteria from a Japanese lake that can effectively break down microcystins, toxic substances produced by harmful algal blooms. These bacteria work well at warm temperatures and alkaline conditions typical of contaminated lakes during summer. The research shows these bacteria contain a special gene that helps them degrade different types of microcystins, offering a promising biological solution for cleaning contaminated water without harmful side effects.

Biotransformation of the Fluoroquinolone Antibiotic, Levofloxacin, by the Free and Immobilized Secretome of Coriolopsis gallica

mycolabadmin

Researchers discovered that a type of fungus called Coriolopsis gallica can break down the antibiotic levofloxacin, which persists in the environment and contributes to antibiotic resistance. They tested both free enzymes from the fungus and enzymes trapped in alginate beads to see which worked better. The study found that free enzymes degraded more of the antibiotic when a chemical helper molecule called HBT was added, while immobilized enzymes were more stable and could be reused multiple times.

Bioremediation Potential of Indigenous Bacterial Isolates for Treating Petroleum Hydrocarbons-Induced Environmental Pollution

mycolabadmin

Scientists isolated three types of bacteria from soil near auto repair shops that can break down petroleum oil pollutants. When tested in the laboratory, these bacteria degraded between 55-83% of petroleum hydrocarbons over 12 days by converting them into simpler compounds. These findings suggest these naturally occurring bacteria could offer an affordable and environmentally-friendly way to clean up oil-contaminated soil without the harmful side effects of chemical cleanup methods.

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.

Biotransformation of Pesticides across Biological Systems: Molecular Mechanisms, Omics Insights, and Biotechnological Advances for Environmental Sustainability

mycolabadmin

This review explains how living organisms like bacteria, plants, and animals break down pesticides through biological processes called biotransformation. The body uses special enzymes to transform pesticides into forms that are easier to eliminate. Understanding these natural cleanup processes helps scientists develop better strategies to remove pesticide pollution from soil and water, protecting both human health and ecosystems.

Enhancing Environmental and Human Health Management Through the Integration of Advanced Revitalization Technologies Utilizing Artificial Intelligence

mycolabadmin

This paper describes how combining artificial intelligence with environmental monitoring can help us better understand how pollution harms our health. The authors propose a seven-step system that collects data on pollution levels in air, water, and soil alongside health information from communities. By using AI to analyze these massive datasets together, scientists and doctors can more quickly identify which pollutants are causing specific health problems and design better treatments for affected people and environments.
