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

Our focus is to optimize the fungal cell wall to both increase chitin production and chitin extractability.

Aspergillus niger is an important industrial producer of organic acids and enzymes producing large amounts of spent fungal biomass.

The research programme Industrial Ecology aims to support the ecological transformation of society and environment towards sustainability. The research subject is Industrial Ecology in its broadest definition, covering environmental systems analysis, and incorporating the social and economic aspects…

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

Promotores: Prof.dr. H. van Veen & Prof.dr. W. de Boer (Wageningen University)

The mycorrhizal symbiosis is among the most widespread species interactions on Earth⁠. This thesis focuses on orchid mycorrhiza, a unique mycorrhizal type that has caught scientists’ attention for centuries⁠.

Our object is to identify and characterize transcription factors involved in lignocellulosic biomass degradation in the filamentous fungus Aspergillus niger.

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.

The soil-dwelling, filamentous bacteria of the genus Streptomyces are renowned for their production of useful secondary metabolites including antibiotics. The work described in this thesis provides new insights on the role and regulation of antibiotic production and resistance in these bacteria.

Many of the most acute problems we face today are global: they transcend national boundaries, they put the future of society and even humanity at peril, and they can only be addressed through international cooperation. However, what can international cooperation deliver? Find out in the minor Ecology,…

Mission: The department of Industrial Ecology is dealing with research into the development of tools for decision making on sustainable production and consumption.

Study information

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…

The aim of this thesis was to develop and evaluate a Ecological Professional Development Model to support preservice biology teachers to direct their own subject-specific ecological professional development route.

Mission: The Environmental Biology department aims to increase the scientific understanding of how current and emerging anthropogenic threats affect biodiversity and ecosystem services. Through this understanding they facilitate strategic management of natural resources by addressing urgent challenges…

Filamentous Actinobacteria, such as Streptomyces, produce a plethora of chemically diverse bioactive metabolites that have found applications across medicine, agriculture and biotechnology.

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.

Acidobacteria is a widely distributed phylum but their functional roles in ecosystem processes are still largely elusive.

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

A liveable planet. More biodiversity. And resources which are being managed wisely. At the CML, we want to make an impact with our research and education. On this website you can read what we do to achieve that.
