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.

How bacteria can reclaim lost energy, nutrients, and clean water from wastewater
A new review explores how technologies using electricity-generating bacteria—like those already piloted at the UK’s Glastonbury Festival and in field trials in Uganda, Kenya, and South Africa—could help us reclaim resources currently being flushed away.

NewsStrategic changes in water treatment could prevent disease outbreaks
A breakthrough new study shows how strategic changes in water treatment effectively treated a deadly outbreak of Legionnaires’ Disease. For the first time, the study provides evidence of an outbreak being stopped by introducing disinfection to previously untreated groundwater.
NewsTeam finds E. coli, other pathogens in Potomac River after sewage spill
Following one of the largest sewage spills in U.S. history, researchers detected high levels of fecal-related bacteria and disease-causing pathogens in the Potomac River, raising urgent public health concerns and underscoring the risks posed by aging sewer infrastructure.
NewsLarge-scale study analyses the impact of climate on Legionnaires’ disease in Catalonia
A study has analysed the relationship between climatic conditions, the presence of Legionella in water systems and cases of Legionnaires’ disease in Catalonia. The link between these different factors highlights the need to adapt prevention and surveillance strategies in the context of climate change.
NewsCARB-X to support development of typhoid fever diagnostic from Chembio
CARB-X is awarding US$1.8 million to Chembio Diagnostic Systems, Inc. to develop a rapid point-of-care test for the detection of Immunoglobulin A (IgA) antibodies to diagnose acute infection of Salmonella enterica serovar Typhi.
NewsPreviously unknown viruses discovered in groundwater
Researchers have created a comprehensive picture of viral diversity and function in a groundwater system. They identified over 257,000 viral operational taxonomic units, i.e. viruses at species level, 99 % of which were previously unknown.
NewsGenes from corn’s wild ancestor change soil microbial community, improve sustainability
Corn bred with genes from wild relatives can reshape soil microbial communities and reduce nitrogen loss — with no yield reduction, according to new research. It’s the first time corn’s genetic makeup has been linked with inhibition of nitrifying and denitrifying bacteria.
NewsLab-grown algae removes microplastics from water
Scientists have applied a revolutionary strain of algae toward capturing and removing harmful microplastics from polluted water. The aim is to repurpose the collected microplastics into safe, bioplastic products such as composite plastic films.
NewsResearchers uncover the invisible worlds beneath our feet
An analysis of a natural aquifer revealed that despite their close spatial contact and possible interactions, the microorganisms in the water and on the rock form two strongly contrasting ecological communities.
NewsResearchers uncover hidden toxin risks during nutrient-starved algal blooms
Researchers have shown that extended nutrient deprivation can significantly increase toxin content per cell in the benthic dinoflagellate Prorocentrum lima, even when cell numbers remain relatively stable. Toxin risk may increase quietly under nutrient-poor conditions without obvious bloom expansion.
