The working group researches to develop a new photobioreactor (PBR). In the PBR microalgae will be cultivated under defined conditions. In the picture a PBR is figured out with the measuring, controlling and steering.
The PBR is created by four independent loop reactors with a reactor volume each of six litres.
Every reactor is highly equipped with instruments. Besides classical parameters (temperature, pH-value, airration rate) also optical density and light climate will be controlled or steered.
The aim of the project is to search for optimal/suboptimal cultivation parameters and their influence on the physiology of microalgae.
The research happens in cooperation with Prof. Dr. Ulf-Peter Hansen, Prof. Dr. Rüdiger Schulz (Working group Plant Cell Physiology and Biotechnology) and the company BlueBioTech GmbH.
