A biorefinery is seen as a viable alternative to the petrochemical refinery. Microalgal biorefineries have a competitive advantage in sustainability because of their operation, which demands mainly light and inorganic substances. In addition to the choice of algal species, the maintenance and management of algal quality in the culture are critical challenges in a microalgal biorefinery. Therefore, automatic monitoring systems contribute immensely to the progress in the biorefinery. By comparing the features of an automated cell counting method with those of standard methods, this review highlights the features of the former method with fluorescence detection of chlorophyll. The method has the potential to guarantee the algal biomass in terms of quality and quantity, resulting in significant contribution to the biorefinery.

生物炼油厂被认为是石化炼油厂的可行替代方案。微藻生物精炼厂的运营具有可持续性的竞争优势，因为其运营主要需要轻质和无机物质。除了选择藻类之外，在微藻生物提炼厂中，维持和管理培养物中的藻类质量也是至关重要的挑战。因此，自动监控系统极大地促进了生物精炼厂的发展。通过比较自动细胞计数方法的特征与标准方法的特征，本综述重点介绍了前者方法的特征，即叶绿素的荧光检测。该方法具有在质量和数量上保证藻类生物质的潜力，从而对生物精炼做出了重大贡献。
