How can we find novel natural products from Actinomycetes that act as growth modulators on mammalian cells? Can we harvest and develop the potential of these novel compounds for industrial and medical biotechnology?

We aim to provide new insights relating to the spectacular multi-cellular life cycle of streptomycetes and other actinobacteria.

Almost all bacteria are enveloped by a cell wall that provides cellular protection.

Can a new proteomics workflow be developed to link genes and gene clusters to bioactive molecules, identify novel compounds and enhance the production in the Streptomyces lividans enzyme?

Bacteria have the ability to alter their morphology in order to adapt to changing environments.

The death of his grandfather in 1988 motivates Changsheng Wu to become a scientist. In 2016, he is awarded the C.J. Kok Jury Award for his thesis on novel antibiotics. Two years later, he will become a Professor at Shangdong University, at the age of 30 years.

Biosynthetic gene clusters (BGCs) for natural products are widespread in microbial genomes, and they are rapidly exchanged. This research assesses the factors that control the spread of BGCs and resistance genes in nature. This includes risk assessment for the spread of engineered DNA in nature.

Development & Disease is one of the four research themes of the Institute of Biology Leiden.

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

Leiden University is partner of the Netherlands Centre for One Health (NCOH). This initiative brings together leading academic research institutes in the Netherlands in an open innovation network that responds to the theme: One Health. NCOH interviewed Doris van Bergeijk: PhD student of the project…

We aim to unravel the complex and intertwining regulatory systems that control development and antibiotic production in streptomycetes.

Chemical biology research at the Leiden Institute of Chemistry is aimed at understanding biological processes at the molecular level to strengthen the knowledge base of human health and disease. The approach to achieve this goal is a fundamental chemical one; with the aid of chemical probes biological…

Antibiotic-resistant bacteria are a major problem worldwide. Molecular biologist Changsheng Wu explored innovative methods of developing new antibiotics more simply and more easily. He also discovered a new type of antibiotic.

Thread-like bacteria make cells that no longer have a cell wall under the influence of osmotic stress. A remarkable discovery, since the cell wall serves as a protection barrier for bacteria. It could also help to explain how pathogenic bacteria can hide in our body from our immune system. A team of…

Symposium

Dennis Claessen has been appointed professor of Molecular Microbiology at the Institute of Biology Leiden. With his teaching and research on the cell wall, the professor wants to establish applications in the industry and the medical sector.
