Macro Algae and Halophytes
Research Field I | Organisms
Driven by the increasing global population growth and the related environmental changes, e.g. decrease of drinking water, available agricultural areas and soil salinization, there is a rising interest in alternative plant-based food sources. Based on the two extreme scenarios "No Land“ and "No Trade“ and the limited availability of fresh water, this food4future sub-project focuses on the use of macro algae and halophytes as salt tolerant food sources.
While macro algae already play an important role in human nutrition, especially in Asian countries, and have recently entered the Central European Cuisine as "sea greens" with increasing acceptance, the consumption of halophytes so far has been neglected.
To investigate the nutritional-physiological potential of the two macrophytic groups and to establish appropriate cultivation methodologies, our project focuses on the study of macrophytic physiological responses (e.g. growth, photosynthetic efficiency, chemical composition in ) to artificially created cultivation conditions, such as salinity, pH, nutrient composition, light spectra or light intensity. Targeted changes in cultivation conditions can lead to an increased production of nutritionally valuable secondary plant metabolites in the macrophytes, thus contributing to a healthy plant-based diet.
The overall aim is the development of cultivation of macroalgae and halophytes in a closed land-based containment system and their use for human consumption. In cooperation with the other food4future partners, innovative sustainable ecological production systems shall be developed, allowing the integrative production of healthy, nutritional macro algal and halophyte biomass in urban areas. In addition to optimizing the production of individual organisms, efficient and flexible co-cultivation compartment systems are to be developed for all food4future organisms.
