Clean water
UNICEF estimates that over 2.2 billion people worldwide do not have access to clean drinking water. Micro-organisms are responsible for a host of waterborne diseases, but simultaneously offer solutions in purifying water and improving sanitation. Biofertilizers offer promising solutions for reduced nutrient runoff and wastewater recycling. As well as applying microbes to combat the problem, applied microbiologists can use their knowledge of health and disease to reduce cases of waterborne disease.

NewsBiochar may help stop antibiotics from escaping through hidden soil highways
A new study reveals that biochar can do more than simply trap pollutants. It may actively redirect antibiotic movement in structured soils, helping reduce the risk of contamination in nearby water systems.
NewsStudy deploys DNA to track infectious bacteria from raccoons via rivers to humans
The emerging infectious bacterium Escherichia albertii has caused outbreaks of severe food poisoning and hospitalized people through contaminated water and foods, such as salad ingredients. A new study suggests a pathway by which invasive raccoons transmit infections to humans.
NewsExploring potential of virovory in combating harmful algal blooms
Toxic cyanobacterial blooms can close lakes, contaminate drinking water and pose risks to human health. A new project is exploring an unlikely tool for mitigating these blooms: virovory, the phenomenon of organisms eating viruses as a food source.

Bacteria organise themselves into diverse, coordinated communities in order to travel across large distances
A new study examined the migration of microbial communities over long distances, and found bacteria migrate not as solitary swimmers, but in diverse, coordinated communities that also contain viruses and “hitchhiking” microbes that cannot swim on their own.

NewsWhy plastic lingers: Water chemistry slows nature’s cleanup
In a new study designed to mimic real environmental conditions, researchers found that the chemical makeup of natural waters significantly delays the breakdown of polystyrene, a common plastic used in packaging and food containers. Because sunlight cannot effectively initiate the degradation process, microbes cannot finish the job.
NewsAntibiotics drive resistance in waterways - even after they break down
Antibiotics continue to drive resistance to bacteria, even after they are broken down in wastewater treatment plants and discharged into rivers and seas, new research published on World Oceans Day has shown for the first time.
NewsNew study provides insights into the control of photosynthesis
Scientists have discovered a previously unknown regulatory mechanism in plant photosynthesis in the unicellular green alga Chlamydomonas reinhardtii. It helps plants adapt to changes in light conditions. A crucial protein interaction at the interface between the two photosystems I and II controls the photosynthetic machinery.
NewsDrug-resistant bacteria found in homes from sewage overflow
A new study shows that sewage overflows in homes can expose people to bacteria that can make them sick, including antibiotic-resistant and multidrug resistant bacteria which can make infections difficult to treat.
NewsMethane emissions maximised by global warming
A new study explains how increases in natural methane emissions will be maximised under future climate warming. It showed that while methane consuming microbes do work harder under warmer conditions, they cannot fully check the extra methane being produced with warming.
NewsArctic river deltas at risk from mounting pressures
Researchers have performed a detailed calculation of the amount of carbon stored in permafrost in Arctic river deltas. In a new study, they point out the risks endangering the storage function of these highly sensitive landscapes due to rapid climate change.
NewsScientists map the microbes behind a climate-regulating gas in India’s busiest estuary — a first
When bacteria in the water and sediment break dimethylsulfoniopropionate down, they release dimethylsulfide (DMS), a gas that drifts into the atmosphere and helps form clouds by seeding cloud condensation nuclei. A new paper reports the first-ever study of DMSP concentrations and the bacteria that degrade it along the entire length of the Cochin Estuary.
NewsNew study uncovers why the Arctic’s rivers are rusting
Scientists have identified the two biggest reasons that once-pristine rivers across the Arctic are growing cloudy with toxic orange iron particles that smother insects and suffocate fish. As the climate warms, a layer of Arctic soil that had been frozen for millennia has begun to thaw.
NewsScientists turn microalgae waste into high-performance membranes for cleaner municipal wastewater
A new study reports a sustainable membrane technology that converts microalgae-derived biochar into an advanced material for municipal wastewater treatment, offering a promising route to cleaner water and waste valorization.
NewsNew study finds neighborhood-level sampling could close equity gap in wastewater disease surveillance
Researchers working with New York State’s wastewater surveillance network found that while the system does a reasonably fair job of including vulnerable populations, it struggles in larger populations when an outbreak is starting, which is when it matters most.
NewsClimate change weakens the purification function of lakes
Lakes play a vital filtering role in the ecosystem: they remove excess nitrogen from the water. An international research team has now shown that climate change could weaken this natural purification process. This would have consequences extending all the way to coastal marine ecosystems.
NewsHospital wastewater reveals drug-resistant fungus strains months before patients show symptoms
A study reveals that sampling raw wastewater closer to the source — sewer lines that directly serve hospitals, retirement homes, and long-term care facilities — allows scientists to detect drug-resistant strains of Candida auris as many as five months before patients begin showing symptoms.
NewsNew ‘permanently wet’ coating method could transform wastewater treatment by helping bacteria survive better
Living bacteria embedded in coatings could clean wastewater, capture carbon and generate biofuels – if they survive the manufacturing process. Researchers have developed a method that keeps bacteria submerged throughout coating formation, increasing the number of surviving cells by around 500 times compared to conventional approaches.
NewsHidden viruses reshape one of Earth’s largest carbon systems, study finds
Viruses play a far more active role in Earth’s carbon cycle than previously understood, according to new research that reveals how they infect and control microbes responsible for carbon production in some of the planet’s largest, darkest ecosystems.
NewsSynthetic biology leads to recyclable textiles: Engineered protein fibers for a cleaner future
Scientists have created protein-based materials, which are produced in bioreactors using genetically engineered microbes. These materials can be readily recycled after use and remade into the same fibers over multiple cycles. In addition, any microparticles, if released from these fibers during washing, would be biodegradable.
NewsSunlight and PVC pipes create a hidden driver of antibiotic resistance
New research shows that chemicals leaching from everyday PVC—especially after exposure to sunlight—can dramatically speed up the spread of resistance genes between bacteria. The effect was strongest at low to moderate concentrations, where the leachate triggered bacterial stress responses without killing the microbes.
NewsFlu signals in wastewater offer an early warning for community outbreaks
A research team has demonstrated that measuring influenza viral RNA in wastewater can be used to estimate community influenza incidence. The approach may help identify outbreak trends about one week earlier than publicly available patient report data.
