NewsFertilizers and extreme heat are damaging coral reefs in the Gulf of Mexico
Scientists analyzing nitrogen isotopes in the calcareous skeletons of corals have discovered that the high levels of nitrogen in the northern Gulf originate from the Mississippi River and are attributable to the use of fertilizers.

NewsRiver drinking water sources may face greater antibiotic resistance risks than reservoirs, study finds
A basin-wide study of 13 drinking water sources in China’s Poyang Lake region shows that water source type can strongly shape the occurrence and spread of antibiotics, antibiotic resistance genes, and resistant bacteria.

NewsPreliminary wastewater bioremediation by photosynthetic Chlorobium genus isolated from pond water
Researchers have isolated naturally occurring light-driven bacteria from local pond water and shown that, within just one week, these microorganisms can substantially reduce the levels of organic pollutants in raw sewage.

NewsBiochar made from brewery waste could help trap harmful bacteria in sandy filtration systems
Researchers have found that biochar made from a common brewery byproduct can substantially improve the ability of sand to retain Escherichia coli, pointing to a potential new use for brewing waste in water filtration and groundwater protection.

NewsNew AI-driven technology could help combat harmful algal blooms
Researchers are developing an innovative technology that could help stop harmful algal blooms before they spread.

NewsRewetting severely wildfire-affected peatlands could deliver unexpected climate benefits
Researchers have found that severely burned peatlands, when rewetted, emit dramatically less methane than unburned or mildly burned ones, suggesting that areas already degraded by wildfire could become prime candidates for accelerated restoration.

NewsHigh-resolution map reveals where veterinary antibiotics enter China’s environment
A new study has developed a high-resolution, county-level inventory of veterinary antibiotic emissions across China, offering researchers and policymakers a clearer picture of where these pollutants originate and where they may accumulate.

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.

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.

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.

NewsCall for input: UK government to overhaul fertiliser regulation
Applied Microbiology International is calling on members to contribute after the UK government proposed a major overhaul of fertiliser regulation through a new framework: the UK Fertilising Product Regulations (UK FPR).

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.

NewsWhen waste becomes fertilizer: Can sludge-derived liquids reshape aquatic life in farmlands?
Hydrothermal carbonization has been proposed as a soil amendment to reduce synthetic fertilizer inputs and enhance crop productivity. Research finds it reshapes community assembly, trophic interactions, and functional expression in periphyton, with network integrity emerging as the primary driver of ecosystem functioning.

NewsLower tillage boosts the soil’s natural phosphorus cycle - cutting the need for costly fertilizer inputs
Long-term tillage reduction helps to restore the soil’s natural phosphorus cycle, supporting more sustainable nutrient management with less reliance on costly and finite fertilizer inputs, according to a new study published in Sustainable Microbiology.

NewsFifteen-year cattle manure application reshapes phoD- and gcd-harboring microbiomes, enhancing vegetable yields
A new study demonstrates that combined manure and chemical fertilizer (M+CF) in an open-field lettuce cropping system enhanced both diversity (+45.3%) and abundance (+290%) of gcd-harboring bacteria.

NewsMicroalgal–Bacterial granules show resilience to estrogen pollution but face structural collapse at high contamination levels
A study reveals both the adaptive biodegradation potential and the vulnerability of MBGS under estrogenic stress, offering new insights for developing robust, biologically based wastewater treatment technologies.

NewsEnvironmental traces of antibiotics found to boost gene transfer among bacteria
Using models of vertical inheritance and horizontal transfer, researchers have found that low doses of tetracycline, ampicillin, kanamycin, and streptomycin stabilize resistance and promote gene transfer across species.

NewsMicrobiome of an entire country is mapped for the first time
An international research team has systematically mapped the microbiome of an entire country for the first time. More than 10,000 environmental samples from across Denmark were analyzed, resulting in an atlas of environmental microbiomes with unprecedented spatial resolution and functional depth.

NewsIsland-wide field surveys illuminate land-sea connections in Mo‘orea
A multi-year scientific expedition determined that land use on tropical islands can shape water quality in lagoons and rainfall can be an important mediator for connections between land and lagoon waters.

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’.
