90年代用于酵母细胞培养的小型化生物反应器装备有加样、pH值控制、气体交换、连续的新鲜培养基供应和在线检测能力。发展这样硬件设备所受到的真正挑战来自要求商品化生物反应器集成几乎所有功能，这需要把它的体积由原来的l升降至365ml(87×63×6mm)，以适应生物柜的II/E型容器。连续培养酵母细胞的新型微型生物反应器被发展了起来，体积87×63×63 mm3，重量610 g。100ml的新鲜培养基能通过微量泵以不同的速率输送入3ml的培养小室。培养物用磁力搅拌子搅拌；pH值、温度和还原电势的变化通过微传感器监视；有一个窗口允许观测培养状态；数据被发往地面分析。这个装置被ESA选用于1994年7月的IML-2飞行任务。生物反应器所涉及的传感器、pH控制、营养泵和液流计均基于硅半导体技术。经过两轮的成功飞行测试，新一代的装置正准备用于2000年的飞行试验。[2] 
培养方法
在地面，用常规方式培养的细胞的生长受到重力的作用，引起细胞聚集物的沉淀。另外，目前实验室和生化工程所用的机械悬浮法(如摇床、机械搅拌、气升法等)使细胞受到剪切力的作用，既容易损伤组织细胞，也影响细胞聚集物的形成。而在微重力环境下，细胞聚集物能向着三维方向生长，从而给了科学家一个模拟体内情况研究细胞间相互作用和组织发育的良好模型。通过细胞单培养(mono-culture)和共培养(co-culture)可以发现有价值的细胞接触方式和作用细节。细胞培养器曾运送到和平号空间站并整合在其生物技术系统(ms)内。培养时间则由光镜和照相监视输出来决定，样品可固定或低温保存以便回地面分析。这是NASA Johnson空间ZX开始研究的，并已初步取得了很好的结果。
在生物材料加工方面，已分离出地面很难分离的哺乳动物特化细胞和蛋白质，其纯度比地面所分离的高4～5倍，分离速度提高柏0～700倍，这些都给药物学研究带来了新的生机。Z大的制药公司已与美国宇航局合作，试图在太空生产出ZL癌症、糖尿病、肺气肿及免疫系统失调的药物。预计到21世纪20年代，在“阿尔法”空间站计划建造的六个实验室里开展的一系列工作，将为生物、医药、工业的进步和人类生活条件的改善开辟捷径。

The 90s miniaturized bioreactors for yeast cell culture are equipped with sample loading, pH control, gas exchange, continuous supply of fresh media, and on-line detection capabilities. The real challenge to developing such hardware comes from requiring commercial bioreactors to integrate almost all functions, which requires lifting their volume from the original l to 365 ml (87 × 63 × 6 mm) to accommodate the biological cabinet II / E Type container. A new microbioreactor for continuously culturing yeast cells has been developed with a volume of 87 × 63 × 63 mm3 and a weight of 610 g. 100 ml of fresh medium can be delivered to the 3 ml culture chamber at different rates by means of a micropump. Cultures were stirred with a magnetic stirrer; changes in pH, temperature, and reduction potential were monitored by microsensors; there was a window to allow for the observation of culture status; and the data was sent to ground analysis. The unit was selected by the ESA for the July 1994 IML-2 mission. Bioreactors involved in the sensor, pH control, nutrition pumps and flow meters are based on silicon semiconductor technology. After two rounds of successful flight tests, a new generation of devices is being prepared for flight testing in 2000. [2] 
Training methods
On the ground, the growth of cells cultured in a conventional manner is gravitationally induced, causing precipitation of cell aggregates. In addition, the current laboratory and biochemical engineering used by mechanical suspension (such as shaker, mechanical stirring, gas lift, etc.) so that the cells subjected to shear forces, both easy to damage tissue cells, but also affect the formation of cell aggregates. In microgravity, cell aggregates can grow in three dimensions, giving scientists a good model for studying cell-cell interactions and tissue development that simulate in vivo conditions. Through cell-mono-culture and co-culture, valuable cell contact and action details can be found. The cell culture device was shipped to the Mir space station and integrated into its biotechnology system (ms). The incubation time is dictated by light and photographic monitoring output, which can be fixed or cryogenically stored for ground analysis. This is the NASA Johnson Space Center began to study, and has initially achieved very good results.
In biomaterial processing, specialized mammalian cells and proteins that are difficult to isolate on the ground have been isolated, which are 4 to 5 times more potent than ground and 0 to 700 times more potent in isolation, all of which give pharmacological studies Bring new life. The world's largest pharmaceutical company has partnered with NASA to try to produce drugs in space to treat cancers, diabetes, emphysema and disorders of the immune system. It is estimated that a series of work carried out in the six laboratories planned by the "Alpha" space station by the 1920s will open a shortcut for the improvement of biology, medicine and industry as well as the improvement of human living conditions.
