英文摘要	Objective To develop a novel and versatile membrane bioreactor for space life science and medical researches in microgravity. Methods Project planning demonstration, blueprint design, manufacture, adjustment and preliminary microorganism culture tests were conducted according to the requirements of microgravity application. Results The bioreactor system consists of 6 subsystems, including liquid storage and supply system, gas storage and supply system,a reactor, gas exhaust system, wastage removal system, parameters measuring and control unit. A bubble-free air supply membrane unit was developed to supply O_2 for the growth of microorganism which improved the O_2 utilization efficiency. A removing unit was manufactured by utilizing a membrane technique that could remove the dissolved CO_2 efficiently. Then the digital signal processor control system was developed for the system parameters monitoring and data storage. The verification tests indicated that the bioreactor system worked well,and parameters,such as power consumption,volume,weight and monitor indexes, met the design requirements. Conclusion The design of the bioreactor system is reasonable and the working principle of O_2 supplying, nutrient mixture and gas-liquid separation is suitable for its requirements in microgravity conditions.
