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.

Cyanobacterial toxins can be inhaled
Research on Southwest Florida cyanobacterial blooms shows that the toxins they produce are aerosolized, potentially being inhaled by people far from contaminated water bodies.

NewsBacteria form ‘herds’ to survive predators, offering fresh insight into Earth’s carbon cycle
Researchers have discovered that tiny photosynthetic bacteria band together into protective ‘herds’ when attacked by predators – a survival strategy that could also influence how carbon is stored in the world’s waters.
NewsKeystone microbes help stabilize nutrient cycling in a massive deep-water reservoir
A three-year genomic study reveals that microbial communities change substantially over time, while versatile keystone taxa help preserve essential ecosystem functions.
NewsBiologist will use €1.63m grant to investigate how microorganisms reactivate their metabolism after prolonged dormancy.
Dr. Sofia Doello has been awarded a grant of around 1.63 million euros for her research through the Emmy Noether program. In her project ’Metabolic foundation of developmental transitions’, she will investigate how microorganisms reactivate their metabolism after a prolonged period of dormancy.

When parasites stop having sex, they may become less picky about their hosts
A new evolutionary theory suggests that some asexual parasites may temporarily be able to infect a wider range of hosts as harmful genetic mutations build up.

NewsWhat D.C.’s algal bloom reveals about a growing water threat
Environmental engineer Steven Chapra speaks out about cyanobacteria algal blooms in the newly renovated Lincoln Memorial Reflecting Pool, expanding on why harmful algal blooms are a growing concern, and what they may mean for freshwater ecosystems.
NewsStudy: China reverses widespread freshwater deoxygenation via wastewater management
Freshwater ecosystems worldwide have been suffering from declining oxygen levels that threatens biodiversity, fisheries, and ecosystem stability. However, a new study offers hope: targeted nutrient management via wastewater control can reverse this trajectory, even in the face of rapid climate warming.
NewsThe climate crisis threatens river microbial biodiversity
A study warns that the biodiversity and biological functions of aquatic fungi in rivers are at risk due to rising temperatures, prolonged dry periods and the loss of riparian vegetation caused by climate change.
NewsUnsafe water still drives global diarrheal disease burden
A new study, analysing data from the Global Burden of Disease 2021 database, found that deaths and disability-adjusted life years linked to unsafe water have declined sharply over the last three decades. Nevertheless, the burden remains concentrated in low socio-demographic index regions.
NewsGlobal port microbiomes reveal hidden biosecurity signals
By analyzing more than 16 million 16S rRNA gene sequences from 1,045 port water samples collected in 23 cities across five continents, a study has found clear biogeographic patterns, a core set of dominant bacterial genera, and widespread potential pathogens.
NewsResearchers aim to autonomously eliminate plant-killing bacteria from hydroponic farming systems
Three researchers have received a nearly $600,000 grant from the U.S. Department of Agriculture to develop a system that can autonomously detect and remove crop-killing microbes from hydroponic farms before they cause damage to plants.
NewsMovement of “forever chemicals” through the Great Lakes
New analysis of 42 years worth of biological records from the Great Lakes, unveils how per- and polyfluoroalkyl substances (PFAS) or “forever chemicals” have moved across the region, contaminating a variety of wildlife.
NewsUrgent hot tub health warning as Britain prepares to sizzle
As Britain prepares to sizzle with temperatures expected to reach 37°C in some areas over the next four days, water experts are warning that a potentially deadly disease can thrive in hot tubs, pools and other domestic water devices.
NewsRice husk biochar catalyst breaks down antibiotic pollutant in minutes
A new biochar supported cobalt oxide catalyst rapidly removes levofloxacin from water while revealing a key reaction mechanism for cleaner wastewater treatment.
NewsEffects of polystyrene nanoplastics and organophosphorus flame retardants on salamander gut-liver axis
New research reveals the effects of polystyrene nanoplastic and the organophosphorus flame retardant exposure on the gut-liver axis of salamanders.
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.
NewsBacteria 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.
