Food security
Millions of people are undernourished globally and with the population growing, food security is a major concern. Food security is multifaceted, requiring advancements in food safety, ensuring products have a good shelf life, reducing spoilage and providing dietary additions to improve the nutrient intake of the population. The application of microbiology is far reaching, and new approaches are required to maintain food security. Through an improved understanding of plant-microbe interactions, it is possible to forecast and mitigate food shortages.

Microbe–fertilizer pair cuts greenhouse soil emissions
A new study shows that inoculating organic fertilizers with denitrifying bacterium, especially when paired with mushroom residue organic manure, reduces N₂O emissions by reshaping the soil microbiome.

NewsBreakthrough for aquaculture: Oral vaccine protects fish from fatal nervous necrosis virus
A novel oral vaccine, that can be mixed into fish feed, provides an effective, practical and cost-effective method to protect fish from the highly deadly nervous necrosis virus.
NewsBiochar helps paddy soils lock away carbon by reshaping microbial life underground
A new study reveals that straw and biochar both increase soil organic carbon, but biochar stores carbon more efficiently by guiding soil microbes toward stable carbon formation.
NewsRice-crayfish farming strengthens soil nutrient cycling
Using metagenomic sequencing, a study has shown that integrated rice-crayfish systems increase the abundance of functional genes involved in methane oxidation, nitrogen degradation, denitrification, organic phosphorus mineralization, and phosphorus transport compared with rice monoculture.

Scientists uncover the hidden air risks in university cafeterias
By assessing two university cafeterias, a new study has shown that both sites had elevated temperature and PM10 levels, while one also showed high carbon dioxide and the other high total bacterial counts.
NewsScientists deploy biofilm-targeting approach to improve crop disease resistance
A new study reports a biofilm-targeting approach for improving crop disease resistance. By replacing the native chloroplast transit peptide (CTP) of MOC1 with a secretory signal peptide (SP), the team redirected the enzyme from chloroplasts to the apoplast.
NewsBiofilm “scaffolds” protect bacterium responsible for food poisoning from antibiotics
Bacillus cereus, which is responsible for human infections and food poisoning, builds organized communities that act as a ‘shield’ against antibiotics, a new study reveals.
NewsThe miracle microbes that could save crops from impact of rising sea levels
A new study reveals a previously unknown mechanism by which microbes help plants – including maize, tomato and rapeseed - survive in harsh environments, with major implications for agriculture worldwide.

A new study shows soil pH regulates the symbiosis between stink bugs and gut bacteria, revealing alternative strategies to pesticides in agricultural pest control.
NewsMicrobes reveal how tillage shapes soil carbon storage
A new study on maize fields in Jilin Province, China, found adding organic carbon sources on top of straw had different effects on the organic carbon in the topsoil in comparison to the subsoil.
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.
NewsTea’s molecular shield against anthracnose
Researchers investigating inducible immune mechanisms activated by tea plants after pathogen infection said the findings show that tea anthracnose resistance is not simply a matter of possessing a resistance-related gene, but of how strongly and rapidly the plant activates its defense network.
NewsTracking melanoidins to improve food-waste biogas recovery
Higher pretreatment temperatures in food-waste biogas recovery can promote Maillard reactions, generating melanoidins. A study shows that melanoidins increase with hydrothermal temperature and inhibit methane production by disrupting methanogenic microbial communities.
NewsHow H5N1 bird flu hid unrecognized for weeks in dairy cattle
A new study reveals why H5N1 influenza infection looked so different in dairy cows, offering a framework for spotting new host species quickly. Instead of affecting the lungs, it caused severe infection in the cows’ udders, largely sparing the lungs.
NewsThe nose knows: Electric schnoz can smell when your food’s gone bad
A new “electronic nose” can detect the scents associated with spoiled food much more accurately than the human nose. It can also sniff out the presence of common food allergens, like walnuts and peanuts, which can be deadly for those with sensitivities.
NewsThe drive to protect Missouri’s $4 billion cattle industry from tick threats
A tiny parasite-carrying tick is posing an outsized threat to Missouri’s cattle. Now, researchers are stepping in to protect the state’s $4 billion cattle industry by tracking different ways the American dog tick spreads a deadly disease known as bovine anaplasmosis.
NewsScientists uncover hidden phosphorus reservoir vital for future food production
Researchers have developed a simpler and more cost-effective method to measure a biologically important form of phosphorus in soils, providing new insights into nutrient cycling that could help improve sustainable agricultural management.

New research suggests that cow’s milk has the edge over plant-based alternatives when it comes to bone strength and nutrient absorption.
OpinionBiopiracy in microbiology: Who owns nature’s resources?
A growing global debate over “biopiracy” is raising urgent questions for microbiologists, researchers, industry and policymakers alike — and Applied Microbiology International is calling on members to help shape the conversation.
NewsJust 10 viral particles can cause H5N1 avian flu infection in cows
Just 10 viral particles of the H5N1 bird flu that caused hundreds of influenza outbreaks in U.S. dairy cattle can cause infection in cows, a new study shows. The research also hints at why the outbreaks have confounded scientists, farmers and livestock handlers hoping to contain and prevent the disease.
NewsPlant viruses open new routes for gene editing
A new study has developed potyvirus-derived vectors for delivering CRISPR RNA (crRNA) guides in Lachnospiraceae bacterium ND2006 Cas12a (LbCas12a)-expressing plants, expanding virus-induced gene editing from tobacco rattle virus (TRV) to tobacco etch virus (TEV), turnip mosaic virus (TuMV), and lettuce mosaic virus (LMV).
