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.

NewsStudy suggests that chlorine treatment may impact the risk of legionnaires’ disease
Preliminary results of a nationwide study suggest that the disinfectant used to treat water before it is distributed through pipes may impact the incidence of Legionnaire’s disease in certain parts of the country.
NewsPreviously unrecognized pathway in plants and phytoplankton offers mercury-detox powers
Primary producers—including phytoplankton—possess a previously overlooked ability to internally break down and detoxify methylmercury. The demethylation pathway rapidly converts methylmercury into less toxic inorganic mercury, which is subsequently reduced to gaseous Hg⁰.
CareersAMR in aquatic ecosystems: A One Health investigation in an irrigation dam in Thailand
Dr Kwanrawee Joy Sirikanchana outlines how her team has launched a major project to address an overlooked question: How much does aquaculture contribute to AMR in shared water systems, and what does this mean for people, animals, and wildlife living around them?
NewsPathogens are the biggest threats at festivals and mass gatherings
A comprehensive review led by public health experts reveals that infectious disease outbreaks and foodborne illnesses are the most common public health threats at youth-focused mass gatherings, ranging from music festivals and cultural celebrations to sporting and religious gatherings.
NewsGroundbreaking technique unlocks secrets of bacterial shape-shifting
Scientists have long known that bacteria come in many shapes and sizes, but understanding what those differences mean has remained a major challenge, especially for species that can’t be grown in the lab. A groundbreaking method could change how researchers study bacterial diversity.
NewsResearchers discover latent antimicrobial resistance across the world
A team of researchers has discovered that latent antimicrobial resistance is more widespread across the world than known resistance. They call for broader surveillance of resistance in wastewater.
NewsMicroalgae could play key role in bio-based circular economy
With food systems under pressure from climate change, geopolitical instability, and supply chain vulnerabilities, the EU is driving innovation toward more sustainable, resilient, and local production models. Microalgae have emerged as a promising resource for producing ingredients across food, feed, and other consumer goods.
NewsHow reactive oxygen species target viruses differently: new clues for safer water disinfection
A new study systematically explored how reactive oxygen species (ROS) inactivate viruses with distinct structures. The results revealed clear heterogeneity: enveloped RNA viruses were most susceptible to oxidation, while double-stranded DNA viruses showed strong resistance.
NewsNew global guidelines streamline environmental microbiome research
A team of nearly 250 researchers from 28 countries has developed a new set of reporting guidelines for environmental microbiomes called STREAMS. The guidelines are organized by the structure of a scientific manuscript and help ensure that important details aren’t overlooked.

NewsNew study finds higher levels of antimicrobial resistance (AMR) in surface water during winter
A new study has found that the levels of antimicrobial resistance (AMR) present in surface water increase during winter. Flooding, sewer overflows and agricultural run-off all contribute to a cocktail of pollutants that can increase AMR genes in surface water, potentially turning regular bugs into ‘superbugs’.
NewsDrinking water people believe to be safe and clean often contain potentially dangerous bacteria
A study in Guatemala found the sources of drinking water people believe to be safe and clean often contain potentially dangerous bacteria. Bottled water sold in large refillable jugs was the most frequently contaminated with coliform bacteria – an indicator of fecal contamination.

A recent review examined microbial biosurfactants as sustainable alternatives to synthetic surfactants in shampoo formulations. The authors addressed the growing demand for environmentally friendly and dermatologically safe cleansing agents, and emphasized the need to transition from petrochemical-based ingredients such as sodium lauryl sulfate (SLS) to biodegradable biosurfactants.
NewsWastewater from most countries favours non-resistant bacteria
Municipal wastewater contains a large range of excreted antibiotics and has therefore long been suspected to be a spawning ground for antibiotic-resistant bacteria. By testing the potential of untreated municipal wastewater from 47 countries to select for resistant E. coli, researchers show that while some samples indeed do so, most instead suppress them.
