title: German CELSS research with emphasis on the C.E.B.A.S.-project.
abstract: In general the German CELSS research program covers both animal and plant systems.  In the field of botany a higher plant growth unit is disposed.  The construction of a continuous culture device for unicellular algae in long-term multi-generation experiments will start in 1990.  In zoology an experimental system for multi-generation experiments, the AQUARACK is already under construction and a running laboratory prototype is surrounded by a wide-spread ground research program.  The combination of the algae system with AQUARACK will result in a combined animal-plant system, the "Closed Equilibrated Biological Aquatic System", C.E.B.A.S. which may be the origin for further interdisciplinary research leading to an aquatic plant-animal-CELSS.  This research field is closely associated with cybernetical science because the development of the combined systems need simulation processes and highly sophisticated electronical control.  A further point in the CELSS program is the study of biological waste management.
