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.

Foxtail barley serves as a host for fungal pathogens attacking barley
Researchers report that foxtail barley (Hordeum jubatum), a wild relative of the cultivated crop, can harbor several fungal pathogens and may play a role in the disease epidemiology of barley, potentially serving as reservoirs of inoculum to initiate some diseases.

Scientists have successfully engineered liquid-liquid phase separation (LLPS)-driven membraneless organelles (MLOs) within the food-grade industrial strain Corynebacterium glutamicum.
NewsNovel technique reveals insights into soil microbe alarm clock
A new study yields clues about when dormant microscopic bacteria and fungi in soil ‘wake up’ and colonize roots, which influences plant growth and health.
NewsAntimicrobial peptides can reduce salmonella in chickens
A new study has found that antimicrobial peptides can combat Salmonella infections in chickens, a major cause of foodborne disease in the U.S. This discovery could help improve food safety and protect public health without relying on antibiotic use.

New study explores ‘legacy effects’ of soil microbes on plants across Kansas
A new study analyzes soils sampled across the state of Kansas to determine the importance of “legacy effects” — or how soils from a specific location are influenced by microbes that have evolved in response to the specific climate at that site for many years.
CareersGlobal Ambassadors: Study visit offers students real-life experience in dairy processing setups
AMI Global Ambassador for Pakistan, Dr. Arsalan Zaidi, reveals how a study visit aimed to provide students with real-life experience in local dairy and cheese processing industrial setups, connecting classroom learning with industrial and research applications.
NewsViral infections at the heart of why honey bees overthrow their queen
Common viral infections shrink a queen bee’s ovaries, reducing both her egg-laying capacity and her production of methyl oleate, a pheromone that normally keeps worker bees loyal. When methyl oleate levels drop, workers will “smell” the queen’s weakness - and begin preparing her successor.
NewsA nose for microbes: how hunger tunes the brain
New research reveals how missing just one essential amino acid can change gene expression and the brain’s sensory systems, prompting animals to seek out protein-rich yeast and gut bacteria that help them restore nutritional balance and survive in times of need.
NewsBiochar and hydrochar show contrasting climate effects in boreal grasslands
Researchers tested how biochar and hydrochar, combined with nitrogen fertilizer, affected greenhouse gas emissions, soil carbon pools, and crop yield in a typical boreal legume grassland. They found that biochar and hydrochar influenced soil processes in opposite ways.
News£4.56M Wellcome Discovery Award to investigate natural human resistance to Salmonella
The University of Liverpool’s Professor Jay Hinton and an international team have been awarded a £4,555,647 Wellcome Discovery funding to lead a five-year research programme exploring how some healthy humans are naturally protected from being infected by Salmonella Typhimurium.
NewsResearchers discover microbes turning food waste into energy
Researchers have identified a previously unknown microbe that plays a crucial role in converting food waste into renewable natural gas, using a molecular tagging approach that could also detect other elusive microbes - including those that are breaking down microplastics in the ocean.
NewsMicrobial iron mining: turning polluted soils into self-cleaning reactors
Scientists have presented “microbial iron mining,” a process where soil microbes activate natural iron cycling. Microbes reduce and mobilize iron minerals, producing tiny iron nanoparticles that act as powerful traps for a variety of pollutants.
NewsRhizosphere metabolites influence the spread of antibiotic resistance genes in soil-plant systems
A study sheds new light on the complex mechanisms by which plants and their associated microorganisms contribute to the migration of ARGs through the environment, offering important implications for food safety and public health.
NewsNearly 1 in 5 urinary tract infections linked to contaminated meat
A new study estimates that nearly one in five urinary tract infections in Southern California may be caused by E. coli strains transmitted through contaminated meat – and people living in low-income neighborhoods are at the greatest risk.
NewsAn edible fungus could make paper and fabric liquid-proof
Researchers report a way to waterproof materials using edible fungus. In a proof-of-concept study, the fungus grew an impervious film on common materials such as paper, denim, polyester felt and thin wood, revealing its potential to replace plastic coatings with sustainable materials.
NewsCommon source, common food vehicle: investigations of recurring Salmonella Strathcona outbreaks in Europe since 2011
Across 17 countries and over a time span of 14 years, 662 cases of the rare Salmonella type have been identified – and linked to small tomatoes from Sicily.
NewsCrop-killing pathogen found to disable plant ‘alarm system’
An international team has discovered that the pathogen Phytophthora infestans - which caused the Irish potato famine - employs special enzymes, called AA7 oxidases, to disable the plants’ early warning system, weakening their defenses before they can respond.
NewsScientists turn algae and crop waste into valuable fuels and nanomaterials
Researchers have developed a clean and efficient process to transform microalgae and agricultural residues into a range of high-value products, including biofuels, bio-adsorbents, and fluorescent carbon nanodots.
