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.

Engineered dual-bacterial sensors turn chemical signals into electricity
Most bacterial information transmission is done via electricity. While electricity-emitting bacteria exist, manipulating them into useful sensors has been quite challenging. Researchers recently developed a flexible bioelectrical sensor system called electroactive co-culture sensing system.

NewsHong Kong’s waters at risk from over-the-counter drug pollution
A recent study of Hong Kong’s river and estuary systems has uncovered an overlooked major source of water pollution: common over-the-counter (OTC) drugs. Accessible, everyday OTC drugs accounted for up to 85% of pharmaceutical pollution in these waters during the wet season.
NewsDon’t build the engine, grow it: biohybrid miniature robots using living organisms
By fusing living organisms like bacteria, algae, and insects with synthetic payloads, researchers are creating living biohybrid miniature robots that self-fuel, self-repair, and navigate environments that would paralyze a rigid silicon chip.
NewsStudy: Microbes show almost universal potential for biodegrading plastics
Researchers have identified more than 600,000 microbial proteins capable of breaking down natural and synthetic plastics, revealing a far broader biodegradation potential across microbes than previously known.

NewsHow soil microbes adapt to life in lakes
Researchers have analyzed the genome of bacteria living in Lake Zurich to conclude that microbes employ two different strategies to colonize new habitats. Some acquire new traits – but others reduce the size of their genome and lose some functions in order to successfully move to a new home.
News‘Safe’ fertilizer linked to extreme water quality loss in Canadian Prairies
Research has found that widespread application of the common farm fertilizer, urea, severely degrades water quality in the Canadian Prairies. Urea added to farm ponds increased growth of algae to levels 10 times higher than seen in other damaged ecosystems, such as Lake Winnipeg in Manitoba.
NewsFunctional traits, not phylogeny, drive gut microbial assembly in estuarine fish
By examining the gut microbiota of 61 sympatric fish species within the ecologically diverse Pearl River Estuary, researchers utilized this “natural laboratory” to disentangle complex biological drivers without the interference of geographical variation.
NewsNameko mucilage: An eco-friendly solution for microplastic pollution
Researchers use natural mucilage from nameko mushrooms for the removal of micro- and nano-plastics from water. The mucilage is rich in polysaccharides, particularly pectin—a naturally occurring plant-based compound—which is known for its particle-binding properties.
NewsHow cholera bacteria swap defenses against viruses
To survive viral attack, bacteria equip themselves with antiviral immune systems. Vibrio cholerae carries a large genetic element called a sedentary chromosomal integron (SCI). A new study investigates whether the SCI might capture gene cassettes from genetic material entering the cell from the outside.
NewsAtomic-level structure of a giant virus revealed
Researchers have successfully determined, for the first time, the capsid structure of Melbournevirus—a member of the giant virus family—at a resolution of 4.4 Å using cryo-electron microscopy.
NewsResearchers develop new solar-powered water disinfection system
Researchers have developed a new solar-powered water disinfection system that combines several existing methods. The compact device effectively utilizes a combination of techniques that all use solar energy.
NewsCorner-loving single-celled microorganism uses geometry to sense its world
A surprising observation in the lab has revealed a remarkable ability in Stentor coeruleus, a single-celled organism about one millimeter long. Sometimes nicknamed the “platypus” of microorganisms for its trumpet-like shape, this tiny creature appears to have a distinct preference for corners.
NewsBacteria incorporate forever chemicals into cell membrane molecules
New research shows that bacteria incorporate polyfluoroalkyl carboxylates—a type of Per- and Polyfluoroalkyl Substances (PFASs)—into the molecules that make up their cell membranes.
FeaturesClear but not clean: the hidden life of drinking water in Nigeria
In many communities across Nigeria, clear water is assumed to be safe. Transparency, both literal and visual, has become shorthand for purity. My recent research in Ede, southwestern Nigeria, began with a simple but uncomfortable question: what are people actually drinking?
NewsOne of cholera’s great enemies is found in the human gut
Cholera-causing bacteria are locked in an evolutionary arms race with a viral nemesis, according to a new genomic study. Researchers found that in the Ganges Delta, cholera bacteria rapidly gain and lose special armour that protects against attacks from the virus, known as bacteriophage ICP1.
NewsTurning algae waste into powerful filters: New biochar membranes clean wastewater more efficiently
A new study has developed a sustainable filtration technology that transforms microalgae waste into high-performance membranes capable of removing pollutants and bacteria from wastewater. The innovation could offer a greener and more efficient solution for municipal water treatment.
NewsWastewater harbors high-risk antimicrobial resistance genes
Researchers found evidence of genetic material from two major bacterial groups, commonly known to exhibit high-risk resistance profiles, in wastewater samples from a large South Africa city.
NewsStopping algae blooms with bacteria-busting buoys
Algae blooms make a pond’s surface shine in mesmerizing green hues. But if the microorganisms responsible are cyanobacteria, they can also release toxins that harm humans and wildlife alike. So, a team reporting in ACS ES&T Water has designed a “set it and forget it” system for distributing algaecide using ...
