| Abstract: |
| Mass-scale cultivation of unicellular Haematococcus pluvialis for natural astaxanthin as a new source of food and functional byproduct has been successfully realized in China because of research and development in the last 30 years. During this period, our research group in IOCAS studied basic scientific principles, developed theoretical and technological knowledge, and performed industrial application and promotion, as well as discovered new solutions to the bottlenecks at important nodes of upstream, midstream, and downstream processes in the H. pluvialis cultivation and astaxanthin production chain, according to the national economic situation, technique conditions, and development status of the microalgal industry. On the occasion of the publication of this special issue to celebrate the 70th anniversary of IOCAS, we provide a brief review of our main achievements on each aspect of H. pluvialis cultivation to promote the sustainable development of H. pluvialis and the entire microalgal industry. The review summarizes the upstream, midstream, and downstream processes, including germplasm resources, cell-cycle-dependent two-step culture mode, and culture optimization. In addition, other key parameters such as automatic control, establishment of closed facilities and photobioreactor scale-up, biocontamination prevention and progress control, bioactive substance extraction and its biofunctional discovery, industry standards, and system construction have also been summarized. Moreover, new research subjects and development trends are also put forward. |
