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

How presence, abundance and enzymatic activities of AM and EM fungi differently affect soil carbon sequestration processes?

Ebru Alazi ‘hacked’ an enzyme-producing system in the fungus Aspergillus niger in order to produce renewable energy more easily. She manipulated the fungus, making it produce more pectinases: enzymes mainly used in the food industry and in the production of renewable energy, such as biofuels. Promotion…

Environmental scientist Nadia Soudzilovskaia has been awarded the prestigious, international Bessel-Forschungs prize issued by the Von Humboldt foundation. This German award is issued to outstanding foreign mid-career scientists that collaborate with German researchers. ‘The combination of different…

Fungi living in vanilla plants play a role in the development of the taste and smell of vanilla, according to Shahnoo Khoyratty of the Institute of Biology Leiden. PhD defence on 27 October.

Music from a compostable cello, photographs and scents of fungi and a woven tapestry. With her upcoming multimedia project Super Organism, visual artist Suzette Bousema enables people to experience the underground fungal network with all their senses. Environmental scientist Nadia Soudzilovskaia and…

What are the global relationships between environmental conditions and abundance of distinct types of mycorrhizal fungi in soil and plant roots?

Leiden researchers have compiled information collected by scientists over the past 120 years into a database of plant-fungal interactions. This important biological data is now freely available for researchers and nature conservationists. Publication in New Phytologist.

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

How the global distribution of vegetation stands dominated by arbuscular and ectomycorrhizal plants relate to principle aspects of belowground carbon accumulation processes?

What are the functions of autophagy in the filamentous fungus Aspergillus niger?

We aim to develop A. niger strains that produce more starch degrading enzymes even in the absence of starch.

This thesis aims to investigate the effect of tripartite interaction between microbial inoculants, the plant, and herbivore insects on the rhizosphere microbiome and volatilome. We investigated the rhizosphere microbiome and volatilome of tomato plants exposed to insect herbivory and/or inoculated with…

This thesis describes the antimicrobial discovery strategy developed in our group, the den Hertog Group at the Hubrecht Institute. It includes a cultivation-based screening approach for novel antimicrobial agents from the source of fungi, and a bacterial time-lapse imaging approach for antimicrobial…

Agrobacterium tumefaciens, a gram-negative plant pathogen belonging to the family Rhizobiaceae, is the causative agent of crown gall disease, which can affect many plant species including agronomically important ones.

We aim to unravel the molecular mechanisms involved in the transformation of eukaryotic cells by Agrobacterium.

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.

We investigate bacteria and fungi to understand their malicious or beneficial impact on food crops and their pathogenic or antibiotic role in human health.

Utilization of plant-originated products as new antibiotics

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.

Microbial Sciences' contribution to the Host-Microbe Interactions research theme is to investigate how beneficial or disease-causing microbes associate and interact with their host.

This project aims to further understand the molecular details related to the biosynthesis and function of Galf containing glycoconjugates in fungal Aspergillus spp.

What is the function of the insect serosa?

Animal Sciences’ contributions to the Host-Microbe Interactions research theme focus on the interaction of animal hosts with pathogenic microbes but also the beneficial role of the gut microbiome.

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

Host-Microbe Interactions is one of the four research themes of the Institute of Biology Leiden.

How soil microbial composition impacts structure and composition of the aboveground plant and animal communities?

Cees van den Hondel, IBL-professor and 2010 Programme director of the Fungus programme of the Kluyver Centre received the royal distinction

Bacteria and fungi on organic dairy farms are significantly different from those on conventional farms. That was discovered by postdoc researcher Sofia Gomes and her supervisors Nadia Soudzilovskaia and Peter van Bodegom in collaboration with the Louis Bolk Institute and Naturalis Biodiversity Centre.…

The master's specialisation Molecular, Cellular and Organismal Biology at Leiden University examines the molecular mechanisms underlying health and disease and how cells and organisms adapt to environmental factors.

A three-volume standard work on galls in Europe. Author Johannes C. (Hans) Roskam is associate professor emeritus in Evolutionary Biology and currently guest at Leiden University.

The Institute of Biology Leiden (IBL) is an internationally oriented institute for research and education in biology.

In the research programme Microbial Sciences we perform state-of-the-art research in the field of biotechnology and microbial sciences.

The research is aimed at development of an efficient gene targeting method that allows controlled integration of DNA at a preselected site in the Trichoderma genome.

Leiden was European City of Science in 2022: for a year Leiden was the capital of European science. Leiden University was a proud partner of Leiden2022.
