Natural vanilla flavor is one of the most important in the world. However, the cost of this flavor is expensive. Production of this flavor by alternative methods, could reduce the cost.

Two bacterial species team up inside the plant root system to rescue their host from fungal infection. This was discovered by a team of microbiologists and bioinformaticians from the Netherlands Institute of Ecology, Wageningen University, and the Institute of Biology Leiden. They also identified the…

Fungal food spoilage often starts with a contamination with spores. Experimental data strongly indicate the existence of subpopulations of spores with different levels of resistance to preservation methods.

This project intends to provide the required knowledgebase for the design of novel mild intervention protocols to prevent fungal food spoilage.

Mycorrhizas are symbiotic associations between soil fungi and most plant species.

The work described in this Thesis is focused on the assembly of oligosaccharide fragments derived from a fungal polysaccharide, galactosaminogalactan (GAG) and fragments of the exopolysaccharide Pel, generated by Pseudomonas aeruginosa.

Fungal infections pose a significant threat to individuals with compromised immune systems and despite advancements in diagnosis and treatment, they continue to jeopardize patient’s health.

Mycoheterotrophy is a particular mode of life in which plants obtain carbohydrates from their associated fungal partners, instead of by using photosynthesis.

China wordt steeds assertiever in zijn relaties met andere landen, maar achter dit beeld gaat een opmerkelijk diverse maatschappij en politieke realiteit schuil die tal van aanknopingspunten biedt voor samenwerking en verdere integratie van China in de wereld. In China een gids voor de 21e eeuw past…

Microbial Sciences'contribution to the Development & Disease research theme is to perform world-class research to understand cellular morphogenesis, growth, development and virulence of microbes.

The overall objectives of my thesis are to investigate the dynamics of the sorghum root microbiome and to explore the beneficial effects of the root microbiome on sorghum growth and stress tolerance.

In this PhD study, I aim to deepen our understanding of the influence of major mycorrhizal types, namely arbuscular mycorrhizae (AM) and ectomycorrhizae (EM), on the global soil carbon cycle and their potential distribution changes under future environmental shifts.

Soil ecologists Emilia Hannula (Leiden) and Elly Morriën (UvA) received the Golden Medal of Teylers Tweede Genootschap on 5 November. They received the prize for their submission to a competition on sustainable soil management.

Vinasse is a major by-product generated by the sugarcane biofuel industry. It is a source of microbes, nutrients and organic matter and often it is recycled as fertilizer.

Plants and soils from natural ecosystems harbor great diversity of soil microorganisms, which could potentially contribute to the sustainability of horticulture. The knowledge about using wild plant species and soil from natural ecosystem to improve the crop health will advance the application of ecological…
