The Leibniz Centre for Tropical Marine Research (ZMT) GmbH (www.leibniz-zmt.de) is an independent research and teaching institute that provides scientific knowledge for the protection and sustainable use of tropical coastal ecosystems. To this end, we work in an inter- and transdisciplinary manner with our partners in the tropics. The ZMT is a member of the Leibniz Association.

Description of the project:

The biggest disadvantage of conventional vegetative propagation of algae is the impoverishment of the gene pool, which can lead to total failure in the event of minor environmental changes. The aim of the project is therefore to develop a modular cultivation system for macroalgae that, for the first time, enables targeted control of sexual reproduction under controlled environmental conditions. This includes both the technical implementation of dynamically regulatable biotopes with marine characteristics and the biological validation of the sexual phases through defined trigger points (e.g., light, temperature, salinity, current). One focus is on the transferability of the system to various macroalgae species with economic or ecological relevance. The core objective of the development is a microprocessor-controlled, cloud-based automation unit that can be freely configured and parameterized. In addition, bio-inspired surfaces and carrier structures are to be developed that promote the targeted attachment of macroalgae spores and zygotes in order to enable a controlled generation sequence and stable establishment of new algae populations.
