Abstract
SYMBIOSE is an ESA supported research and development program which aims at establishing a first pilot model of aclosed ecological system, compatible with operation in weightlessness conditions, and dedicated to scientific investigationsin the microgravity environment. It integrates microalgal photosynthesis within an artificial ecosystem featuring asymbiotic strain of C~oreUa (241.80, GOttingen), which synthesizes and excretes substantial amounts of maltose, and isfurther looped on a consumer compartment. A technological concept has been developed. It is presently being integrated inorder to gain knowledge on the system dynamics, and ultimately demonstrate the feasibility of such a biotechnology.Preliminary work on the photosynthetic metabolism of this microalga is being undertaken in order 1) to support later amathematical formalisation of the dynamics of this artificial ecosystem, and, on this basis, 2) to compensate for its lack ofstability with model-based external control. The most recent results are presented, along with a new design of thephotobioreactor which integrates efficient light energy capture, microgravity compatible gas transfer and reduced shearstress
