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.

The broader a fungus’s diet, the better it kills insects and helps plants
Entomologists have discovered that a single underlying trait—metabolic breadth, or the range of nutrients a fungus can use—links its ability to kill insects, partner with plants and thrive in different ecological roles.

NewsCould your salad be the source? Pathologist discusses reported parasite outbreak in US
Amid reports of a parasite outbreak that has sickened people in several states across the U.S., a pathologist warns that it is likely linked to a widely distributed commercial food product.
NewsWild yeast discovery enables non-GM brewing of ornithine-enriched craft beer
Researchers have uncovered a naturally derived yeast mutation that boosts ornithine production while preserving brewing performance for value-added fermentation.
NewsCould ‘Trojan horse’ microbes that exploit symbiotic systems be candidates for new biological pesticides?
Researchers have discovered a new insect pathogen that invades the gut symbiotic organ of stink bugs by mimicking their symbiotic microorganism, and this pathogen ultimately kills the host bugs.

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.
NewsScientists 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.
