Symposium
International Rhodobacter Symposium 2025
The second international Rhodobacter Symposium follows after a successful first edition. We would like to again bring together the scientific community working with the intriguing purple bacteria such as Rhodobacter (Cereibacter) sphaeroides. This edition is organized with support of the EU Cost Action PurpleGain. It will be an informal symposium centered around different topics related to their physiology and applications in biotechnology.
Preliminary programme
The symposium will only have plenary sessions that go into various important aspects of purple bacterial applications and physiology. The scientific committee has invited several outstanding speakers (see below). Information about the programme will follow as soon as it becomes available.
The symposium will focus on the following topics:
- Purple bacteria biotechnology
- Genetic tools
- Microbial physiology
The symposium is now opened for abstract submission. You can use this abstract format to prepare your contribution. Please submit your abstracts to ruud.weusthuis@wur.nl before April 15, 2025. The scientific committee will select oral and poster presentations. A limited number of speakers will be eligible for financial compensation by PurpleGain.
Registration
Registration for this symposium is free of charge; however, we request contributions for lunch and dinner. You can select these options during your registration.
