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.

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.

How 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.
NewsCows vs plants: which milk delivers the greatest health benefits?
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).
NewsFermentation science may offer new route to better lower-alcohol wine
In addition to finding ways to ferment grape juice without producing as much alcohol, one scientist is exploring novel yeasts and methods to overproduce aromas to compensate for their eventual loss when reducing alcohol through grape juice dilution.
NewsStudy reveals 45 new toxins produced by bacteria associated with foodborne infections
Researchers have discovered 45 new toxins produced by Salmonella bacteria, some of which are associated with foodborne infections. The study shows that these substances primarily act in the competition among microorganisms for space and resources.
NewsDegradable sensors reveal hidden soil secrets
New degradable sensors being developed by soil scientists track biological activity in soil by having a degradable substrate that is nibbled on by microbes.
NewsSlow down, microbes: When wheat learns to protect the nitrogen
Wheat plants can do more than grow grain. Research shows that their roots release natural compounds that slow down soil microbes and keep nitrogen in the soil potentially cutting losses, greenhouse gas emissions and costs for farmers.
NewsBiochar triggers a five-year soil recovery cascade in acidifying rice paddies
A long-term field study reveals how biochar reshapes soil chemistry, microbes, viruses, and metabolites to support healthier agricultural ecosystems.
NewsTwo types of biochar help alfalfa survive salty soils
A new study shows that carefully designed biochar can guide plant metabolism and reshape beneficial microbial communities around the roots to help reduce stress from saline-alkali soil.
NewsBiochar and beneficial microbes team up to restore polluted soils and boost crop growth
A new review examines how biochar-immobilized microbes can help clean contaminated soils, improve soil health, and support crop growth. By analyzing evidence from 92 published studies, the authors provide a data-driven overview of how this technology works and what is needed to bring it closer to practical use on farms.
NewsWarming may weaken biochar’s climate benefits in cropland soils, global study finds
Researchers found that warming significantly increased carbon dioxide emissions from soils treated with biochar by an average of 77%. The effect was especially strong in croplands, where emissions increased by 117.5%, compared with 30.9% in forest soils.
