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.

Industrial-scale biotech production of proteins and vitamins economically viable
Researchers are developing biotechnological methods called “power-to-protein” and “power-to-vitamin” processes which use microbes to produce proteins and vitamins for human consumption using basic chemical ingredients – entirely bypassing livestock farming and agriculture.

Breakthrough in engineering color-sensing yeast
In a new study, scientists engineered baker’s yeast to sense and respond to different colours of light, enabling new ways to control cellular behavior with red and blue light.
NewsResearchers look at ‘genetic neighborhoods’ to find pathogenic bacteria
Researchers used a machine-learning approach to study not just which genes a bacterium has, but also where those genes sit next to each other, helping to distinguish disease-causing strains of a poultry pathogen from nonpathogenic strains.
NewsMarine heatwaves pose hidden threat to human health
Prolonged periods of unusually high ocean temperatures can trigger a cascade of effects that ultimately affect human health, from worsening extreme weather events and reducing seafood supplies to increasing mental health challenges.
OpinionWhose culture is it? Rethinking the study of traditional fermented food microbiomes
When microbiologists study traditional fermented foods, are we simply documenting natural biodiversity, or are we also accessing a form of cultural heritage, asks Tara Spencer-Drakes, PhD.
NewsProtein-enriched ketchup gets a boost from algae extracts
Added protein is showing up in foods from breakfast cereal to pasta, but not many condiments … yet. Researchers have now developed an enriched tomato ketchup by incorporating protein extracted from microalgae.
NewsResearchers discover a fungal protein that causes leaf loss in crops
A research team has succeeded in gaining insights into the genetic basis of “defoliation” caused by the pathogenic fungus Verticillium dahliae. A key protein they have identified is responsible for the aggressive nature of the fungus.
NewsNo-tillage and microbial fertilizer work together to build carbon in nutrient-poor albic soils
A field study in northeastern China shows that combining reduced soil disturbance with microbial organic fertilizer can increase soil organic carbon across both surface and deeper soil layers.
NewsBiofortified millet benefits toddlers without supplement side effects
Toddlers who ate iron- and zinc-biofortified pearl millet for nine months did not experience adverse effects typically associated with increased iron intake and developed gut microbiomes with distinct and potentially beneficial changes.

A new study could change climate prediction models by enabling region-specific, microbe-targeted strategies to mitigate greenhouse gas emissions from agricultural ecosystems.
NewsSilencing a fungal wall protein cuts powdery mildew on melon leaves
Powdery mildew fungi survive on living plants behind a cell wall that provides both structural support and a shield against host immunity. Researchers have now identified the fungal cell wall assembly protein ECM33 as a weak point in that defense.
NewsOxygen nanobubbles turn biochar into an active defense against cadmium in flooded rice soils
A newly engineered biochar maintained oxygen around rice roots, shifted cadmium into more stable soil forms, and substantially reduced cadmium accumulation in rice plants.
NewsCould understanding leaf surfaces lead to new ways to prevent crop disease?
Researchers have adopted a biointerfaces approach to the problem of fungicide resistance in plant diseases. Rather than treating fungal diseases with nontargeted fungicide application, they suggest looking at the location where plant-fungi interactions begin: the leaf’s surface.
NewsHow does a deadly chicken virus escape vaccines designed to slow it?
A new genome-wide study of the Marek’s disease virus identified 10 regions in the genome associated with what makes certain strains more virulent, and could inform next-generation vaccines.
