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.

Could livestock-originated probiotics replace synthetic antibiotics for livestock?
In many developing countries, the use of antibiotics in both humans and animals is often indiscriminate and poorly regulated. Could livestock-originated probiotics be a suitable replacement?
NewsFertilizer boosts soil’s ability to lock away carbon
The 180-year experiment at Rothamsted — the world’s longest-running agricultural trial — has revealed that long-term application of nitrogen and phosphorus fertilisers can significantly increase the amount of carbon stored in farmland soils, helping to mitigate climate change.
NewsCompound from Antarctic microorganism can be used to produce food, cosmetics, and medicine
A bioactive compound produced by the microorganism Bacillus licheniformis, found on Deception Island in Antarctica, has properties that qualify it for use in producing food, cosmetics, pharmaceuticals, and biodegradable materials.
NewsNew study reveals diverse threats from Avian E. coli
New research has determined why various strains of Avian Pathogenic E. coli behave so differently. The study analysed a colibacillosis outbreak in turkeys in the UK, and found a strain called ST-101 was the dominant cause of the outbreak, accounting for nearly 60% of cases.
NewsStructural diversity of pyripyropenes via biosynthetic gene cluster design and heterologous expression in Aspergillus nidulans
Researchers have designed a reconstituted biosynthetic gene cluster (BGC) for producing structurally diversified deacetylated pyripyropenes, using the native pyripyropene A BGC from the wild-type strain Aspergillus fumigatus Af 293 as a template.
NewsValorization of soybean-processing wastewater sludge via black soldier fly larvae: performance and bacterial community dynamics
A new study indicates that the valorization of soybean-processing-sourced sludge via black soldier fly larvae was achieved via functionally important BSFL intestinal microbiota, providing an efficient recycling approach for similar waste streams.
NewsRoot chemistry determines how antibiotic resistance spreads from manure to crops
Researchers found that the rhizosphere, the narrow soil zone surrounding plant roots, is a major hotspot for the accumulation of manure-derived ARGs. Across eight common crops, ARG abundance in rhizosphere soil was on average 1.24 times higher than in bulk soil.
NewsScientists develop safer and more sustainable antimicrobials to prevent infection of cow udders
A new study has unveiled an alternative class of potent antimicrobial compounds that could be used in the agriculture industry to combat multi-drug-resistant bacteria that cause bovine mastitis.
NewsFrom glucose to gourmet: engineered bacteria churn out key food additive
Researchers used E. coli as the chassis to produce inosinic acid (IMP), a popular umami enhancer. By reprogramming the metabolic flux network of E. coli and introducing amino acid mutations in the key enzymes in the synthesis pathway, the yield was significantly increased.
NewsPoultry growers: Have you checked your water lines lately?
Water quality could impact the kind of microbial populations in poultry drinking water lines and lead to the buildup of a biofilm that can harbor pathogenic bacteria like Salmonella, according to a new study.
NewsResearchers uncover hidden plant–microbe strategy that boosts crop growth under nutrient stress
Scientists discovered that when soil microbes compete with each other in the rhizosphere, they release a well-known compound called glutathione. This compound enhances plant growth under sulphur-deficient conditions.
NewsSlime mold metabolites are a promising, eco-friendly repellent of root-knot nematodes
A team of researchers has discovered 14 compounds secreted by slime molds that repel root-knot nematodes (RKNs) - worm-like parasites of the genus Meloidogyne - and could be the source of new, non-toxic anti-RKN pesticides.
