Microalgae could become an important renewable source for chemicals, food, and energy if process costs can be reduced. In the past 60 years, relevant factors in open outdoor mass cultivation of microalgae were identified and elaborate solutions regarding bioprocesses and bioreactors were developed. An overview of these solutions is presented. Since the cost of most microalgal products from current mass cultivation systems is still prohibitively high, further development is required. The application of complex computational techniques for cost-effective process and reactor development will become more important if experimental validation of simulation results can easily be achieved. Due to difficulties inherent to outdoor experimentation, it can be useful to conduct validation experiments indoors. Considerations and approaches for realistic indoor reproduction of the most important environmental conditions in microalgae cultivation experiments-light, temperature, and substance concentrations, are discussed.
如果能够降低加工成本，微藻有望成为化学品、食品和能源的重要可再生来源。在过去60年里，已确定了微藻开放式户外大规模培养的相关因素，并针对生物工艺和生物反应器制定了详尽的解决方案。本文对这些解决方案进行了概述。由于目前大规模培养系统生产的大多数微藻产品成本仍然高得令人望而却步，因此需要进一步发展。如果能够轻松实现模拟结果的实验验证，那么应用复杂的计算技术来开发具有成本效益的工艺和反应器将变得更加重要。由于户外实验存在固有困难，在室内进行验证实验可能会有所帮助。本文讨论了在微藻培养实验中真实再现最重要环境条件（光照、温度和物质浓度）的注意事项和方法。
